Boeing delivered the first 747-8 with performance-improved GEnx-2B engines as part of the airplane's Performance Improvement Package (PIP.)

A Cathay Pacific Airways Cargo 747-8F Freighter was the first aircraft delivered with the new PIP engines.

The engine is the first of the package's three improvements to enter service. The two other components, Flight Management Computer (FMC) software upgrades and reactivation of the horizontal tank fuel system on the passenger version, the 747-8 Intercontinental, are expected to enter service later this month and in early 2014, respectively.

The PIP engine improves the airplane's efficiency by 1.8 percent. All three PIP components can be retrofitted on the 747-8. The tail fuel reactivation is applicable only for the 747-8 Intercontinental and the FMC upgrades can also be made to existing 747-400s.

Etihad kicks off Dubai airshow with mamomth Boeing 777-9X, 777-8X and 787-10 order

by Devesh Agarwal

From top, clockwise, Boeing CGI of Etihad 787-10, 777-8X, 777-9X
United Arab Emirates' (UAE) national carrier, Etihad Airways PJSC, kicked off the Dubai Air Show with a massive order for 56 wide-body Boeing aircraft with options to purchase for an additional 26 aircraft taking the quantity up to 82 at a list price valuation of $25.2 billion.

The Abu Dhabi-based carrier's order includes 25 777X airplanes, comprising 17 777-9Xs and eight 777-8Xs, subject to program launch. Etihad Airways is the first airline to order the 777-8X and will be a launch customer of the airplane, which is expected to enter service around the end of the decade. The order includes options and purchase rights for 12 additional 777X airplanes.

The airline also ordered 30 Boeing 787-10 Dreamliners, the high-capacity, medium-haul, and longest member of the Dreamliner family. Combined with the carrier's previous orders for 41 787-9s, today's order makes Etihad the world's largest airline customer for the Dreamliner family with a total of 71 787s on order. The order includes options and purchase rights for an additional 12 787-10s.

Today’s announcement also includes the milestone 1,000th Boeing 787 Dreamliner to be ordered.

Etihad also ordered one Boeing 777F freighter which is based on the 777-200LR.

The 777X is the upgrade of the venerable Boeing 777 family featuring new composite wings as seen on the 747-8 and 787 family aircraft, along with new GEnx engines which GE promises will be about 10% more fuel efficient. The 777X

The Boeing 777-9X is a stretched, more fuel-efficient version of Boeing ultra-popular 777-300ER. Typically seating 400 passengers, the 777-9X will be capable of flying the same distances as its predecessor, but with up to 40 more passengers, with lower operating costs and reduced fuel consumption per seat. The 777-9X was launched less than two months ago with an order from German flag carrier Lufthansa. Eithad is expected to start receiving its 777-9X from 2020.

The Boeing 777-8X is an upgraded version of the ultra long-haul Boeing 777-200LR, which Etihad recently purchased from Indian flag carrier Air India, to serve the Abu Dhabi – Los Angeles route. The -8X will replace the LRs when the start arriving in 2022. [Read our analysis on why the 777-200LR is ill-suited to Air India's operations]

The Boeing 787-10 is the largest and latest version of the Dreamliner family, typically carrying more than 320 passengers, up to 50 more than the 787-9 which Etihad Airways will introduce late in 2014. The aircraft will be capable of flying between Abu Dhabi and medium-haul destinations such as Dublin or Johannesburg, and it is expected to be deployed on high capacity medium haul routes by the airline. Final assembly and flight test of the 787-10 are set to begin in 2017, with first delivery targeted for 2018. Boeing launched the 787-10 earlier this year, at the Paris Air Show.

All the aircraft in this order will be powered by General Electric GE9X, GEnx and GE90 engines. Etihad ordered 57 GE9X engines which will power Etihad Airways’ 25 new Boeing 777X aircraft, 68 GEnx-1B engines for the airline’s 30 new Boeing 787-10 aircraft, and two GE90-115B engines which will be used on its new Boeing 777-200F freighter.

Etihad Airways currently has 86 aircraft in operation, with more than 80 aircraft on firm order. Its last major aircraft deal was made at the Farnborough Air Show in 2008, where Etihad Airways announced firm orders for 100 aircraft, including 45 Boeing aircraft, in a long-term order which was at the time one of the largest in aviation history.

GE Aviation testing new composite fan blades for the GE9X engine

by BA Staff

Image courtesy GE
GE Aviation has begun testing on its new composite fan blades for the GE9X, the next-generation GE90 engine that will power Boeing’s 777X aircraft. This validation test is the first of several testing programs GE has planned this year for the GE9X fan module.

The first round of fan blade tests occurred in June at the ITP Engine testing facility in the United Kingdom and focused on validating the new composite material for the fan blades. The results were very positive. GE plans a second round of tests at ITP later this summer to further validate the new fan blade composite material and a new metal material for the fan blade leading edge.

This fall, GE plans to run Universal Propulsion Simulator (UPS) fan performance tests on a fan rig at a Boeing facility in Seattle, Washington. Work is already under way on the fan rig and facility for these tests.

Bill Millhaem, general manager of the GE90 Program at GE Aviation.
“The GE9X fan blade will feature new high-strength carbon fiber material and a steel alloy leading edge,” “This new material, along with a higher fan tip speed, will improve the efficiency of the low-pressure turbine (LPT) and deliver more than 1.5 percent fuel efficiency improvement compared to the GE90-115B engine.”
The GE9X fan module incorporates several unique features. The GE9X front fan will be the largest of any GE engine at 132 inches in diameter and include a durable, lightweight composite fan case similar to the fan case on the GEnx engines which power the Boeing 787 and 747-8 aircraft. Compared to a metal fan case, the composite fan case will lower the weight by 350 lbs. (approximately 160 kg) per engine.

The fan blades in the GE9X engine will be fourth-generation composite fan blades. GE Aviation developed the first composite fan blade for its GE90-94B engine in 1995. Composite fan blades are also featured in the GE90-115B and GEnx engines. GE has accumulated 36 million flight-hours with composite blades and anticipates accumulating more than 100 million flight-hours when the GE9X enters service later this decade.

The GE9X engine will have 16 fan blades, which is fewer blades than the GEnx and the GE90-115B engines. This fan blade reduction is possible as a result of advancements in three-dimensional (3D) swept design that enables engineers to create a more swept design and large fan chord. The new high-strength carbon fiber material allows the blades to be thinner than blades made from current carbon fiber material, with the same strength and durability. These improvements will drive fuel efficiency improvements and hundreds of pounds of weight reduction from fan blades and the structure needed to support them.

The lower blade count and new carbon fiber composite material will enable GE Aviation to increase the fan tip speed. The increased tip speed will improve the efficiency of the LPT, enabling a reduction in the LPT blade count and contributing to the engine’s fuel burn improvement.

The GE9X engine for Boeing’s 777X aircraft will be in the 100,000 pounds thrust class with a 10 percent improvement in fuel burn over today's GE90-115B. Key features include: a 132" fan diameter; composite fan case and fourth-generation composite fan blades; next-generation 27:1 pressure ratio high-pressure compressor; a third-generation TAPS (twin annular pre-swirl) combustor for greater efficiency and low emissions; and ceramic matrix composite (CMC) material in the combustor and turbine.

GE Aviation has been conducting tests on new materials and technologies for the engine during the last few years. Along with fan blade tests at the ITP Engine testing facility in the United Kingdom, GE Aviation will test a high-pressure compressor rig at GE’s Oil & Gas facility in Massa, Italy, this month. The first engine will test in 2016, with flight-testing on GE’s flying testbed anticipated in 2017. Engine certification is scheduled for 2018.

The GE9X will follow the highly successful GE90-115B engine that entered service in 2004. Rated at 115,000 pounds of thrust, the GE90-115B engine includes such performance-enhancing features as a 3-D aero compressor and wide-chord, swept composite fan blades for greater efficiency. The dual annular combustor emits no more than 40 percent of the hydrocarbons allowed by today's international standards. In addition, today's GE90-115B engines have been enhanced to reduce fuel burn by 3.6 percent from the 2000 launch specification.

More than 1,500 GE90-115B engines have been ordered by customers for their Boeing 777-300ERs, 777-200LRs and 777 Freighters. In 2011, the GE90 engine experienced its most successful order year and accumulated airline and freighter operator commitments for 400 engines, surpassing the 250 engine commitments record from 2007.

Snecma of France and IHI Corporation of Japan are revenue-sharing participants in the GE90 program.

NTSB issues urgent safety alerts for GEnx engines; Air India, JAL, Ethiopian, Qatar 787 Dreamliners affected

The National Transportation Safety Board, the independent safety investigator of the United States, has issued two urgent safety recommendations (A-12-52 and A-12-53) on General Electric GEnx engines, which power the latest generation of Boeing aircraft; the 787 Dreamliners and the Boeing 747-8 both freighters and Intercontinental passenger jets.

The GEnx-1B engines power the 787 Dreamliners operating with Air India, Japan Airlines (JAL), Ethiopian Airlines, and soon, Qatar Airways. The two other 787 operators All Nippon Airways (ANA) and LAN Chile, have their aircraft powered by the Rolls Royce Trent 1000 engines.

The GEnx-2B engines power the Boeing 747-8i of Lufthansa and the 747-8F freighters of many carriers.

The investigation of the GEnx engines began with the July 28th engine failure incident at Charleston, SC, USA, involving a Boeing 787 Dreamliner destined for Air India. Initial investigations suggested a fracture failure of the fan midshaft (FMS), first reported by Bangalore Aviation. While that investigation is still on-going, on August 31, the NTSB found similar indications on another GEnx-1B fitted on, a yet to fly, 787. The fan midshaft was removed from that engine for further inspection and examination. As a result of the investigative work to date, the NTSB has determined that the fan midshafts (FMS) on the GEnx engines fractured or cracked at the forward end of the shaft where the retaining nut is installed.

Exemplar image of GEnx Fan mid-shaft

The NTSB is also concerned about a loss of power on the GEnx-2B engine of a Boeing 747-8F cargo flight, operated by Air Bridge Cargo, at Shanghai, China, during take-off. The airplane had accelerated through 50 knots when the engine's low pressure rotor speed dropped. The pilot rejected the takeoff and returned to the ramp. Photographs of the low pressure turbine show damage similar to the GEnx-1B engine from the Charleston incident.

The urgent recommendations are: (1) (A-12-52) Issue an airworthiness directive to require, before further flight, the immediate ultrasonic inspection of the fan midshaft (FMS) in all GEnx-1B and -2B engines that have not undergone inspection, and (2) (A-12-53) Require repetitive inspections of the fan midshaft at a sufficiently short interval that would permit multiple inspections and detection of a crack before it could reach critical length and the fan midshaft fractures.

NTSB Chairman Deborah A.P. Hersman said
"The parties to our investigation -- the FAA, GE and Boeing -- have taken many important steps and additional efforts are in progress to ensure that the fleet is inspected properly," "We are issuing this recommendation today because of the potential for multiple engine failures on a single aircraft and the urgent need for the FAA to act immediately."
The engine manufacturer, GE, has developed a field ultrasonic inspection method to inspect the fan midshaft in the area where the fracture and crack occurred. This inspection can be done with the engine still installed on the airplane, thus saving operators a lot of money and downtime. To date, all in-service and spare GEnx-1B engines have been inspected. In addition, all GEnx-2B engines on passenger airplanes have been inspected. However, as per the the NTSB, approximately 43 GEnx-2B engines mounted on 747-8F cargo airplanes have not yet been inspected, and this is a concern on potential fan midshaft failures.

Read the full safety recommendations here.

The NTSB is still continuing its investigations, but these safety recommendations have the potential of snow-balling in to a major issue for national carrier Air India. After the Charleston incident, delivery of the first 787 for the carrier was delayed, with Indian aviation regulator, the DGCA, slow to grant safety clearance. At least two possibly three 787s were due to be delivered in rapid succession in the next few weeks. Will the carrier delay induction awaiting clarifications from the engine manufacturer?

Prudence demands they should. After all, engines can make up more than 30% the cost of the aircraft, and need to be beyond 100% reliable.

NTSB traces Air India Boeing 787 GEnx engine failure to fan mid-shaft fracture

The United States National Transportation Safety Board (NTSB) released an interim report on the progress of its investigation in to the failure of a General Electric GEnx engine on-board a Boeing 787 Dreamliner destined for Air India on July 28th last. The have traced the failure to a fracture on the forward end of the Fan Mid-Shaft.

Bangalore Aviation has exclusive obtained this exemplar image showing approximate location of the failure.
Exemplar image of GEnx Fan mid-shaft

The National Transportation Safety Board continues its investigation of the July 28, 2012 contained engine failure that occurred on a Boeing 787 Dreamliner during a pre-delivery taxi test in Charleston, South Carolina. A contained engine failure is a specific engine design feature in which components might separate inside the engine but either remain within the engine’s cases or exit the engine through the tail pipe. This design feature generally does not pose immediate safety risks.

Last week, the NTSB sent an investigator to the scene to gather information on the incident and subsequently launched a full investigation into the cause of the failure, led by NTSB Investigator-in-Charge, Mr. David Helson.

On August 1, 2012, a team of experts from the NTSB, FAA, Boeing and GE Aviation specializing in engine systems and metallurgy traveled to a GE facility in Cincinnati, OH to disassemble and examine the failed GEnx engine. GE is the manufacturer of the GEnx engine. The parties to the investigation have been extremely cooperative in assisting NTSB personnel in its review and assessment.

As a result of the investigative work to date, the NTSB has determined that a fan mid-shaft on the failed GEnx engine fractured at the forward end of the shaft, rear of the threads where the retaining nut is installed. The fan mid-shaft is undergoing several detailed examinations including dimensional and metallurgical inspections.

GEnx engine cut-away drawing not part of NTSB release.
The GEnx engine is a newly designed aircraft engine. It is a “dual shaft” engine, meaning that one shaft connects the compressor spool at one end to the high pressure turbine spool at the other end. A longer “fan shaft” connects the fan and booster in the front of the engine to the low pressure turbine in the back.

The cockpit voice recorder and flight data recorder, which is a combined unit on the 787 Dreamliner, was transported to the agency's Recorders Laboratory in Washington, DC for processing and readout. Both recordings captured the event and analysis is ongoing.

Moving forward, investigators will continue the detailed examination of the engine and metallurgical analysis of its components. The investigators have also begun reviewing the engine manufacturing and assembly records.

This investigation is ongoing. The information released today is factual in nature and does not include any analysis. Additional factual information may be released as it is developed.
Engine experts in India say that the main component carrying shafts inside an engine are an important part of the engine, but it is too early to say whether this fracture was caused due to materials flaw, a fault in manufacturing, or a design flaw. Depending on the reason for failure, it has the potential to become serious. However, the NTSB has not issued any recommendations yet. Boeing is due to deliver a GEnx powered 787 to Ethiopian Airlines early next week.

Boeing 787 Dreamliner destined for Air India suffers serious engine mishap. NTSB to investigate

The second Boeing 787 Dreamliner to be built at the airframer's Charleston, South Carolina facility suffered a serious engine mishap during pre-flight testing on the afternoon of Saturday. This aircraft is due to be delivered to national carrier Air India as VT-ANJ.

A Boeing spokesperson told Bangalore Aviation
"A 787 experienced an engine issue July 28 while undergoing preflight runway testing in North Charleston. As the NTSB investigates, Boeing and GE are working closely with the agency and are committed to resolving the issue appropriately.

While the investigation is in its early stages, we are unaware of any operational issue that would present concerns about the continued safe operation of in-service 787s powered by GE engines. However, should the investigation determine a need to act, Boeing has the processes in place to take action and will do so appropriately."

As per The Post and Courier newspaper report
Debris from a brand new Boeing 787 Dreamliner's engine fell onto the runway and into the grass at Charleston International Airport Saturday afternoon, sparking a fire, shutting down the airport and diverting flights for more than an hour.
The incident occurred around 16:00 local (01:30 IST). The Charleston airport spokesperson said "the airport closed around 4:30 p.m. and reopened at 5:41 p.m."

The gravity of the incident is serious enough to merit an investigation by the US National Transportation Safety Board (NTSB).

The aircraft is powered by the General Electric Co. GEnx engine. Japan Airlines is currently the only operator of GEnx powered 787s with four aircraft in its fleet. The only other operator of the 787, launch customer, All Nippon Airways (ANA), uses the Rolls Royce Trent 1000 engines.

Engine manufacturer GE released this statement to Bangalore Aviation
"During a ground test run in North Charleston on July 28, a GEnx-1B engine on a non-revenue generating Boeing 787 aircraft experienced an issue. No one was injured.

About 100 GEnx engines are in service, and they have accumulated more than 125,000 flight hours.

GE continually monitors and analyzes the performance of the GEnx fleet in service, and we are not aware of operational issues that would hazard the continued safe flight of aircraft powered by these engines."
Boeing operates Dreamliner assembly lines in two locations, both in the US. Charleston in South Carolina and Everett in Washington. The Charleston facility rolled out its first 787 Dreamliner, also destined for Air India as VT-ANI, earlier this year, in April.

This incident comes within the week after ANA partially grounded some of its 787s after corrosion was found in its Trent 1000 engine gearbox components.

The GEnx engine is also used to power the newest version of the venerable Jumbo Jet, the 747-8.

Lufthansa takes delivery of first Boeing 747-8i. Expected to be deployed to India ahead of Chicago and Los Angeles

Launch customer and German flag carrier Deutsche Lufthansa AG has taken delivery of the first Boeing 747-8 Intercontinental (747-8i or 748i), the latest variant of probably the most recognised airplane in the world.

Lufthansa is getting the airplane which is registered D-ABYA ready for its delivery flight to Frankfurt on May 1. Boeing will host a celebration with senior executives from both companies that day while Lufthansa will host a special celebration when the airplane arrives in Frankfurt on May 2.

An informed source has indicated, that is almost certain, that Lufthansa will deploy the 748i to India, ahead of an announced deployment to Chicago and Los Angeles.

India is the second largest market for the carrier, after the US, and with India's civil aviation ministry refusing to act on the airline's long standing requests to operate the Airbus A380 superjumbo to Delhi, Lufthansa desperately needs the 747-8i to rejuvenate its Boeing 747-400 cabins which are a generation behind the competing Gulf majors. Similarly, Lufthansa is expected to upgrade the Bangalore route to the 748i in order to continue its leadership of the lucrative IT traffic with California, especially San Francisco.

The 747-8i called "The Queen of the skies" uses improvements inspired by those originally developed for the Boeing 787 Dreamliner. These include a new curved, upswept interior architecture giving passengers a greater feeling of space, increased space for cabin baggage and other personal belongings. The aircraft features Lufthansa's new business class. (See photos and video here).

The 748i is powered with GE Aviation's GEnx-2B engines which offer significantly reduced noise and fuel consumption levels.

Analysis: Air India's $1 billion compensation claim on Boeing for 787 delays is baseless

Earlier this week, reports surfaced that India’s national carrier Air India was asking for roughly $1 billion in compensation from US original equipment manufacturer (OEM) Boeing for the roughly 3 year delay of the Boeing 787-8.

With Air India’s initial delivery having been pushed back almost 2.75 years by the natural program delays and further delay of the delivery of Air India’s 787s into early 2012 because of a failure to complete the final certification requirements of the General Electric GEnx-1B engines with the United States Federal Aviation Administration (FAA), Boeing is certainly culpable for these delays. Air India will be the first airline to receive GE-powered 787s, with multiple 787-8s featuring Rolls-Royce’s competing Trent 1000 already plying commercial flights around the globe.

However, when Air India first signed a contract for the 787-8, compensation was capped at 0.5% of the order’s list value, which at that time roughly $3.24 billion due to under-pricing of the 787 by Boeing (it was priced at $120 million then, now at $193.5 million). This would translate to a cap on compensation of $162 million. Of course Boeing naturally had to soften this stance given the image problems created by the 787 delays, even offering about $500 million in compensation.

However, the fact remains that $1 billion in compensation is far, FAR too much for Boeing to have to pay. Air India’s economic losses on the 787 delays are far from $1 billion, as the following analysis should indicate, and as such, we feel that Air India is completely out of line in asking for this much money to pump into their black hole of an operation.

Please consider a few things before reading this analysis. Firstly, these are “back-of-the-envelope” calculations, so to speak; they do not represent Air India’s internal analyses but rather the best “apples-to-apples” estimates we could come up with. Secondly, these are highly optimistic projections, utilizing best case scenarios. Thirdly, the origin of the operating cost data is from my report “Hot Air- The Mid Sized Widebody Race in Early This Decade,” a copy of which can be purchased at Air Insight’s online store for US$ 49 (INR 2,500). I cannot share more details of this data as it would violate certain NDAs and represent conflict of interest between my various ventures.

With all of that being said, here are the major assumptions present in this analysis. The 787-8 is projected to meet all range targets and is thus able to make Chicago/Toronto-Delhi nonstop in both directions with a full passenger load. Air India was to receive 20 787s over the first 3 years of the program; this is an estimate based off the timeline for the delivery of their first seven 787-8s (VT-ANA through ANH) outlined in early December. We are choosing to ignore the fact that Air India was in fact moving to defer their own 787 deliveries by two years in 2009 before being “bailed” out by Boeing’s delay, which would invalidate both this analysis and Air India’s claims. Because the 787 deliveries are staggered, we are projecting that the average of 20 787-8s will only occur in Air India’s fleet only over the last two years of that period and thus we are amortizing the net loss over 2 years.

Based on extensive research of Air India fares over the next 6 months, we have estimated the following typical yield mixes for Air India’s 3 cabins; $234 per flight hour for first class, $136 per flight hour for business class, $67 per flight hour for economy class. In each case, we are assuming 75% loads for first class, 80% loads for business class, and 85% loads for first class to calculate lost revenue potential (rounding to the nearest passenger for each case). We feel comfortable in making these assumptions because Air India has a relatively price inelastic customer base: they charge roughly the same fare for each class on both the 777-200LR and 777-300ER on the same route (where there are aircraft swaps) despite the 777-300ER having 43.7% more seats.

There are two models through which we can measure the impact of the 787 delays on Air India’s finances over the past two years. The first is the replacement model, under which the 20 787s would directly replace the 777-300ERs and the 777-200LRs. These two fleets combined for Air India have an average daily utilization of about 11 hours per day in summer 2012, and as such are similar to Air India’s projected 11.78 hours per day total utilization of the 787-8s denoted in the RFP for sale-leaseback from December. Under this model, the cost to AI comes from the lost savings of the 787-8 vs. the 777s net of the lost revenue potential, plus the (very small) marginal benefit of having the passenger friendly and reliable 787-8 in their fleet.

Utilizing this model, we first turn to the 777-300ERs, which have average daily utilization of roughly 9 hours per day, multiplied by 12 aircraft in the fleet for 108 hours per day. Under our estimates, the 777-300ER is on average (for Air India’s routes) $7600 less efficient than the 787-8 per flight hour. Under Air India’s configuration however, the aircraft has 4 more first class seats, 17 more business class seats, and 65 more economy class seats. Under our projected loads, that represents an advantage of 3 first class, 14 business class, and 55 economy class seats. This translates to $6291 of lost revenue potential, which creates a net loss of $1309 per flight hour. Spreading that over 108 flight hours per day over 2 years translates to a net loss of $103.2 million.

Moving to the 777-200LR; this aircraft has 8 more first class seats, 17 more business class seats, and 43 fewer economy class seats. It also costs $5000 more to operate per hour than the 787-8. Under our load factor assumptions, this represents 6 more first class seats, 14 more business class seats, and 34 fewer economy class seats. Thus, the lost revenue potential is just $963 per flight hour, yielding a net loss of $4037 per hour. Spreading that over the 14 hours of daily utilization for 8 aircraft or 112 hours of daily utilization, the net loss over 2 years is $330.1 million.

Summing the costs of these two brings us to $433.3 million, or close to the sum initially offered by Boeing. Given the cascade of bad news that has overcome Air India over the past 3 years, it’s not impossible to tack on another $70 million or so to account for the rising costs of negative customer perception and interest fees on accumulated losses, bringing us essentially to a nice round figure of $500 million.

The second model that we can use is a model of lost revenue/opportunity. Under this model, Air India (as it has for the most part indicated it plans to do) would use the 787-8s primarily for expansion. Thus the cost to Air India of the delay is simply the lost profitability of the 787 (revenue per flight hour minus cost per flight hour), plus the marginal loss of flow traffic (connections) and potential frequent flyers (who might have jumped over to Air India with the new routes).

This model poses a set of unique challenges, however, the first being that it’s hard to find the requisite 236 hours of daily utilization or so that would be required to meet Air India’s projections. That being said, we’ll assume that they do in fact operate these flights and this utilization.

In terms of yields, there will be some drop off due to the added capacity. In terms of the true addition of capacity, Air India’s utilization figures from the RFP indicate that 20 787s would add about 4.4 million annual seats to Air India’s network. From a perspective of Air India’s network, that represents about a 26% increase in seat capacity (measured in available seat miles). Using a consensus of estimates of the price elasticity of demand for air travel and Air India’s unique demand streams, we’ll allow Air India the benefit of the doubt for this exercise, and build in just a 15% drop in yield for Air India (smaller in magnitude than the increase in capacity). Under our model, this would mean that business class yields were $116 per flight hour, and economy class yields were $57. Under this model, the sudden rise in capacity also would decrease load factors by just 5 percentage points in each class; to 75% in business class and 80% in economy class. Under these conditions, the 787-8 would have 14 business class seats filled, and 190 economy class seats filled.

With average cycle length of 5 hours and average annual utilization of 4300 hours, the 787-8’s operational profitability under the conditions denoted above would thus be roughly $119 million over the two years. This operational profitability is a best case scenario (and hard to envision given Air India’s current status of not even covering costs of fuel on some long haul flights), and does not include the financial costs (lease rates and/or depreciation) of operating the aircraft.
Building in $100 million for the effects of increased flow traffic through Delhi and Mumbai, as well as another $50 million for the effect of increased frequent flyer retention (both very generous estimates), plus $100 million for all other effects, including increased negative customer perception and accumulated losses (and the resultant interest charges). Even adding up these highly optimistic charges, we still reach a sum of $469 million, less than the sum Boeing has offered.

So it should be abundantly clear that Air India has very little basis to claim $1 billion in compensation. It would appear rather, that a carrier who is seeking a $6 billion bailout from the Indian government to fund loss-making operations from the next decade is simply looking to soak Boeing for more cash (funding a whopping 1 year more of Air India operations) so as to slightly delay the timing of their next bailout, which we can be sure will at least double in size. Air India is building off of the baseline of other, profitable, carriers who have valid claims for compensation from Boeing, but should not be allowed to do so.
