June 18, 2021, ©. Leeham News: We continue our discussion about the Transport Category (FAA Part 25) certification rules.
Last week we talked about how much tougher the birdstrike protection is for Part 25. Now we look at the fuel tanks and the inherent explosion risk in these.

June 17, 2021, © Leeham News: A key question hanging over the used widebody market is what percentage of available aircraft could be converted into freighters.
Indeed, existing passenger-to-freighter (P2F) conversion providers are ramping up capacity and new ones are coming online. However, much of the P2F capacity growth is focused on converting used 737s and A320-family aircraft.
Airbus and Boeing foresee a market for 1,500-1,600 conversions over the next 20 years. While Boeing doesn’t break out its forecast between single-aisle and widebody aircraft, Airbus believes 670 of these will be widebodies.
In this analysis, LNA explores the size of the market, key providers, conversion capacity, and likely buyers of converted aircraft.
June 14, 2021, © Leeham News: One of commercial aviation’s most influential leaders said last week Boeing needs to replace the 737 with a new technology airplane.
Steven Udvar-Hazy, chairman of Air Lease Corp., said in a CNBC interview June 9 the 737 is a good airplane, but the time has come for a replacement.
“Boeing has to look at the future. What kind of airplanes that airlines will need with all the environmental challenges, regulatory challenges? What is the airplane type airlines will need 5, 10, 15, 20 years from now?” Hazy said.
“Boeing needs to invest. The 737 is a wonderful airplane, but it’s been in operation since 1967. We have an airplane that its basic design has been around for 54 years. It’s time for a new technology airplane that will give airlines and the public greater efficiency, better economics, better environmental footprint so the airlines can make money with it and yet meet the challenges that we’re facing on the environmental front.”

June 3, 2021, © Leeham News: Boeing and Alaska Airlines today outlined a five month ecoDemonstrator program in a series of tests designed to “green up” commercial aviation.
Boeing partnered with airlines and suppliers beginning in 2012. Alaska is the eighth airline to participate. A Boeing 737-9 will be the current platform.
Boeing will flight test 20 technologies and ideas with Alaska beginning June 29 and ending Dec. 2.
Not all ideas fall strictly within “new technologies.” Some are weight-reduction initiatives that aggregate to lower airplane weight, which in turn reduces fuel burn. This in turn reduces carbon emissions.
But other ideas directly go to environmental efforts addressing noise, emissions and now COVID infectious worries.

June 3, 2021, © Leeham News: Lessors are expected to write down the value of their widebodies as the long-haul travel slump appears set to extend well beyond this year, LNA reported last week.
A tidal wave of excess widebodies has reduced ownership costs to historic lows. Prices will only go lower as lessors finally initiate distressed-asset sales, and lease rates will continue to fall as used widebody inventory grows.
A confluence of factors, topped by the availability of lower-cost used widebodies, could increase the cost advantage of low-cost carriers over legacy competitors – at the same time reduced business travel and lower yields reduce the gap between legacy and LCC unit revenue.

On May 25, 1979, an American Airlines McDonnell Douglas DC-10 crashed on take off from Chicago’s O’Hare International Airport. Within minutes, it was known that the No. 1 engine separated from the airplane just after the airplane was committed.
The aircraft gained a few hundred feet before rolling over on its left wing, crashing into a trailer park. All 271 on board and two people on the ground were killed.
The Federal Aviation Administration immediately grounded all DC-10s in the US because of the engine separation. Regulators elsewhere in the world followed suit.

May 25, 2021, © Leeham News: Michael O’Leary may be royally pissed as Boeing, but he’s nevertheless in negotiations for a large order of 737-10 MAXes.
In the year-end earnings call last week and in an appearance on CNBC, O’Leary unloaded on Boeing’s Seattle management team over delivery delays for the 737-8200.
O’Leary, the CEO of Ryanair, didn’t mince words—he never does. This is, after all, the guy who at a press conference talked about his potential trans-Atlantic low fare operation providing blow jobs to business class travelers. Sitting next to him was his female translator, who clearly was nonplussed. (You can look it up on YouTube.)
