Now we address an even larger problem for SST engines, the takeoff and landing noise.
Sept. 13, 2018, (c) Airfinance Journal: Air Lease’s executive chairman Steven Udvar-Hazy says that Boeing could make a decision on whether or not launch the 797 model mid-year 2019.
If so, the timing could coincide with the Paris Air Show.
“In the NMA market, whether Boeing will launch the 797 is a ‘multi-billion dollars question’, he says, adding that right now the US manufacturer is assessing the engine availability.
“There are two potential engines applications. They are all derivative engines,” he says at the UK Aviation Club Lunch on 13 September.
“We all know the problems that Airbus and Boeing have been going through with the new engines on the Max and the Neo as well as the 787s,” he adds.
And for him Boeing is very ‘cautious’ on a decision. “They are trying to understand what is the real market demand for this aircraft and all indications points out to a decision sometimes in the middle of next year,” he says.
Sept. 10, 2018, © Leeham News: While Boeing Commercial Aircraft grapples with more than four dozen unfinished 737s clogging the space at Renton Airport and Boeing Field, Boeing Defense had some good news last week:
The KC-46A received certification from the US Federal Aviation Administration and the first delivery is due for late October.
Final military certification is still to come and the wing-pod drogues need certifying, but at long last, Boeing can move forward.

Lufthansa Airlines is sabotaging history and its own airplane restoration project.
Lufthansa, the airline that honors its history with the airworthy Junkers JU-52, flying it around Europe garnering millions of Euros of publicity in the process.
Lufthansa, which agreed to restore one of just 44 Lockheed L-1649 Starliners to full LH colors and make it flyable.
The engines have been run up. The airplane was assembled. First flights were planned for next year.
And now, Lufthansa is pulling the plug.
Despite media inquiries and questions from leaders of the project, Lufthansa hasn’t said why it is shutting down the effort to create an airworthy airplane.

May 31, 2018, © Leeham News: We continue our analysis why the Airbus A330neo has lost to Boeing’s 787-9 in recent sales campaigns. In the first part of the series, we analyzed the key data of the aircraft, including their weight, drag characteristics and payload capacity.
Now we continue with flying the aircraft over typical routes with our performance model. What’s the route capacity of the of the aircraft and how about their fuel consumption?

May 24, 2018, © Leeham News: Boeing’s 787-9 has won some important fights against the Airbus A330neo. After Hawaiian Airlines, American Airlines and a possible loss at United, one asks: Is the A330-900 not competitive against a 787-9? The aircraft are similar in size and use the same engines.
We take a deeper look at the A330-900 compared with the 787-9 to understand what’s behind this trend.

May 17, 2018, © Leeham News: The recent agreement between the US and the Gulf carriers limits the expansion of the carriers on the US market. As the premier long-range destination area from the Gulf is the US market, this will influence the lift needed by the three.
All three carriers, Emirates, Qatar Airways (Qatar) and Etihad, have decided on the 777-9 as the mainstay for their long-haul needs. With the change, the question arises, will Qatar increase the buy of the A350-1000 instead of taking the 777-9 and will any of the others reconsider?
To understand what’s involved we compare the capacity and the costs of the 777-9 and A350-1000. How large is the difference? Is the A350 the better choice if the extreme long-haul capacity needs decline?
May 14, 2018, © Leeham News: The engine problems are getting worse.
These have moved beyond the technical issues with the Rolls-Royce Trent 1000, GE Aviation GEnx, Pratt & Whitney GTF and CFM56.
The problems are trickling down to the maintenance, repair and overhaul shops.
LNC previously touched on the back-up in MRO shops due to the RR Trent 1000 problems, affecting even Trent 700 (Airbus A330) MRO scheduling. We’ve also reported the knock-on effect of the GTF MRO on other engine shop visits.
The mandated-inspections of CFM56 fan blades in the wake of the Southwest Airlines accident last month inundated MRO shops with unexpected visits.
Now, a European appraisal company forecasts that the “bow wave” of CFM56 shop visits will create a crisis for spare engines and parts.

May 10, 2018, © Leeham News: American Airlines last week ordered 30 additional regional jets. Of these, 15 were the Embraer E175. No surprise there. It’s the traveler’s favourite and the market leader among US regional jets. But American Airlines also ordered the same number of Bombardier CRJ900. Why? Isn’t it a bit dated?
There are good reasons for this order and Bombardier sees a new spring for the trusted regional. We use our performance model to understand why.
April 23, 2018, © Leeham News: Even before last week’s Southwest Airlines accident raised the focus on aircraft engines, industry officials were becoming worried that problems with engines powering the Boeing 747-8, 787, 737 MAX and Airbus A320neo may lead to stricter certification standards by regulatory authorities.
There is also emerging evidence that the issues with the Rolls-Royce Trent 1000 on the 787s may negatively impact Airbus’ sales efforts with the A350. The A350 is powered by an entirely different RR engine, the Trent XWB, which by all accounts has had a virtually trouble-free entry into service.
But it’s a Rolls-Royce engine and airlines affected by or watching RR’s response to the Trent 1000 problems are skeptical about the Trent XWB, LNC is told.
