Irkut MC-21 missing ultimate load test
By Bjorn Fehrm
April 05, 2017, ©. Leeham Co: United Aircraft’s IRKUT MC-21 passed 90% of the static Ultimate load test end February at the TsAGI test institute in Moscow, reports ATO.RU. But the aircraft failed the 100% test.
The test simulates a load which is 150% higher than the highest load that the aircraft should be subject to in its operational life. The test failure does not stop the aircraft from beginning flight testing, for that the aircraft needs to pass the limit load test (highest load during flight), which it has.
Missing the Ultimate load test for new airliners is nothing unusual. The designers tries to pass this test with the smallest possible margin. Any excess margin will make the aircraft unnecessary heavy. Other aircraft to have missed the test are Mitsubishi Aircraft’s MRJ, Airbus’ A380 and Boeing’s 787.
According to ATO.RU, who quotes IRKUT, the reinforcements in the wingbox necessitated by the failure will weigh 25kg. It’s not clear if the changes will affect the start of test flights. These should have started during April.
Pegasus Airlines, bridging Europe and Asia
By Bjorn Fehrm
April 05, 2017, ©. Leeham Co: Turkey’s Pegasus Airlines has its operations center south of Hungary’s Wizz Air that we wrote about last week. With a hub in Istanbul, the Turkish LCC connects Europe and West Asia/Middle East.
Pegasus is a fraction larger than Wizz Air and had the same dynamic development until last year, when the internal unrest in Turkey threw a spanner in the airline’s growth. Read more
No new design needed for turboprops, says Bombardier
- Part 1, ATR, appeared last week. Today’s interview with Bombardier completes the two-part series.

Introduction
April 4, 2017, © Leeham Co.: Bombardier doesn’t think a new, clean-sheet turboprop aircraft is needed any time soon, a position that stands in contrast with rival ATR.
Bombardier Q400.
Ross Mitchell, VP Commercial for BBD, believes the Q400 covers the turboprop segment from 70 to 90 seats and its operational flexibility covers everything airlines need today.
However, ATR has 85% of the backlog with BBD capturing the other 15%.
Still, Mitchell gives a strong defense of the Q400.
Summary:
Don’t believe everything ATR claims about operating cost advantages, BBD says.
BBD can move cockpit and wing production from Canada to lower costs—but where is the question.
Re-engining the Q400 isn’t in the cards, at least any time soon.
Pontifications: Branson gets pissy over dropping the Virgin America name
By Scott Hamilton
April 3, 2017, © Leeham Co.: Sir Richard Branson came to Seattle last week to promote the new service by Virgin Atlantic Airlines to London. In a hissy-fit, he promptly pissed on Alaska Airlines for the business decision to drop the Virgin America brand in 2019.
Alaska, of course, acquired Virgin America last year. The acquisition didn’t sit well with Branson, who nevertheless made out well in the deal.
Although Alaska officials said they would decide later whether to retain the Virgin brand, only those with wishful thinking gave any chance of this happening.

Branson certainly knows this. In 1997, Virgin Group acquired the low fare carrier Euro Belgium Airlines for $60m and promptly dropped the name in favor of Virgin Express.
VE lasted only nine years; it ceased operations in 2006 when it was sold and merged into the new Brussels Airlines.
Branson’s whining over Alaska’s decision to operate the merged operations into the Eskimo’s image smacks of hypocrisy.
Let’s also remember that his Virgin Atlantic is 49% owned by Delta Air Lines, which is building a hub in Seattle in competition with Alaska. The fight between Alaska and Delta is sometimes bitter.
Branson’s criticism of Alaska might have as much to do with Virgin Atlantic’s partnership with Delta as it does his own bruised ego.
Could an NMA be made good enough, Part 2?

Introduction
April 3, 2017, © Leeham Co.: In the first part of our investigation on how good an NMA can be, we explored low weight and drag fuselage design. We will now continue with the design consequences for the fuselage construction and the cabin.
What drives whether one goes for an Aluminum or CFRP (Carbon Fiber Reinforced Polymer) fuselage?
Figure 1. The NMA takes more and more the shape of a 767 replacement (A United 767-200 pictured). Source: United.
What will be the typical dimensions for an NMA fuselage and what will be passenger capacities?
Summary:
- An elliptical fuselage will force a CFRP design.
- The fuselage door configuration will be critical for cabin capacity and flexibility.
Naming games
March 31, 2017 (c) Leeham Co.: With the likelihood appearing greater and great Boeing will launch a new, middle of the market sector airplane, what’s the name
Is “A360” a name for the next Airbus aircraft? Or would it be the butt of jokes? Rendering via Google images.
going to be?
Steven Udvar-Hazy, chairman of Air Lease Corp, already calls it the 797. We agree, though until this is a done deal, we’re calling it the 7M7 while in development.
If Airbus responds with a stretched A321neo–anything but a certain prospect–the working title among the press has long been A322. Airbus officials have occasionally called it the A321 Plus-Plus, a name that will hardly roll off the tongue.
If Airbus were to respond with a new twin-aisle, either smaller than the A330-200/800 (which aren’t selling these days) or about the same size, what would this be called? Skipping to A400 doesn’t work: the name is taken by the A400M, which in any event is a snake-bitten name.
Then, what will the replacements for the Boeing 737 and Airbus A320 be called.
It’s already assumed “797” is the name of the widely expected Boeing middle of the market airplane. Rendering via Google images.
For Boeing, the “797” runs out the string of 7 Series choices. For Airbus, folklore says it rejected the name “A360” because of the jokes that would be made about the airplane flying in circles if an issue required a return from its takeoff point. According to the same folklore, “A370” was rejected because the “7” harks to Boeing’s 7 Series.
So: just for fun, let’s have some naming contests.
Bjorn’s Corner: Aircraft engine maintenance, Part 5
By Bjorn Fehrm
March 31, 2017, ©. Leeham Co: In the last Corner, we showed flight hour graphs for wide-body engines. Now we will deduce the market for engine overhauls from these graphs.
It will show which engines are still in engine manufacturer care, in their main maintenance cycle and in the sun-set phase.

The phase the engine is in and its future flight hour development will decide the attractiveness of the engine for overhaul organizations. Read more
Boeing plots support for 747-8
March 29, 2017, (c) Leeham Co.: Boeing is going to build and buy its own 747-8Fs, then lease them as a way to keep the 747 line alive, reports Bloomberg News.
With the effective shutdown by Congress of the U.S. Export-Import Bank — which traditionally has helped overseas carriers purchase planes — Boeing lost a key sales tool. Making matters worse, leasing companies have been hesitant to finance a plane with a dwindling customer base,” Bloomberg writes.
There are already five white tails, aircraft built for customers that canceled or deferred deliveries indefinitely. Nippon Cargo Airlines just canceled two aircraft, scheduled for delivery this year, which takes this to seven. Others that have canceled or deferred: Arik Air and Transaero. A twice-announced “commitment” from Volga-Dnepr Airlines/Air Bridge Cargo 20 747-8Fs failed to materialize more than four.
Wizz Air, the LCC of Central and Eastern Europe
By Bjorn Fehrm
March 29, 2017, ©. Leeham Co: Wizz Air was formed in Hungary 2003 but its largest market is in Poland since operations began. Today, the airline is Europe’s fifth largest LCC, flying to 125 destinations spanning 39 countries.
The airline was established as a private company in Budapest with main investor, Indigo Partners, from USA. Operations started in Poland 2004. Wizz Air, financially registered in Jersey, lost money at first. Gradually, traffic and load factors improved and the airline has posted profits since 2012.
Annual average growth of traffic and revenue in recent years has been around 20%. Wizz Air is listed on the London stock exchange since March 2015. Read more
