Understanding ODAs

April 19, 2022, © Leeham News: Following 737 MAX grounding, Boeing was found to have exerted undue influence on their ODA unit and its members.
ODA stands for Organization Designation Authorization. The Federal Aviation Administration (FAA) designates personnel employed by a company to be its official on-site representatives. The MAX crisis put a spotlight on the Boeing-FAA ODA relationship. Faults were found and the uninformed in many cases thought the existence of ODAs was a scandal. But it’s a system that’s been around for decades, and it’s not limited to Boeing.
Let’s look at exactly what that means as we try to understand the impact on certification schedules at Boeing.
Boeing’s Product Certification Timelines and Challenges

April 18, 2022, © Leeham News: US Rep. Peter DeFazio, the chairman of the House Transportation Committee, is on record opposing a certification extension for the Boeing 737-10 Max. Under legislation previously passed by Congress, Boeing has until the end of this year to certify the MAX 10.

DeFazio is a Democrat from Oregon who is not seeking reelection this year. He was a fierce critic of Boeing during the House hearings of the MAX crisis. His opposition to extending the certification timeline for the MAX 10 is bad news for Boeing. It was the path of least resistance to completing the Max 10 certification without implementing a new Engine Indicating and Crew Alerting System (EICAS) system on the airplane. Requiring EICAS will greatly complicate the certification path and future crew training differences with the rest of the 737 Max models..
How did we get here?
In the wake of the two MCAS-related 737 losses, Congress passed new laws regarding Aviation Safety. The most sweeping of them was the Aircraft Certification, Safety, and Accountability Act. This is a broad stroke law addressing 37 different portions of the FAA’s review process. It changes a great many things inside Boeing as well as inside the Federal Aviation Administration.
Let’s look through these changes and see how the process changes will impact things.
Pontifications: Rolls-Royce and the Next Boeing Airplane
April 18, 2022, © Leeham News: The aviation industry is waiting to see what Boeing will do when it comes to a new airplane.
By Scott Hamilton
The Next Boeing Airplane (NBA), whatever form it takes, will largely be driven by what advances in engines are available. Boeing CEO David Calhoun downplays the engine element. He’s said repeatedly that the next engine will only have about a 10% lower fuel consumption than today’s powerplants. He didn’t today’s name engines, but the benchmarks are now the Pratt & Whitney Geared Turbo Fan and CFM LEAP.
Calhoun places more emphasis on a moonshot in design and production advances to lower the cost of the airplane—with the theory the price paid by the customer will be lower as a result, providing a combined benefit of lower operating costs and lower capital costs.
PW agrees that by around 2030, the usual date (plus-or-minus a year or two) given for the NBA’s entry into service (EIS), it can get another 10% of improved fuel economy out of the GTF. CFM, on the other hand, is pressing ahead with what used to be called the Open Rotor concept. CFM now calls it an Open Fan. The company has a target EIS of 2035 and a fuel improvement of 20%. Emissions for the two engines would be reduced by roughly a corresponding amount vis-à-vis fuel burn.

Introduction
April 14, 2022, © Leeham News: Last week, we speculated that Airbus might decide to upgrade the present A330-200F freighter to a neo variant based on the longer -900 fuselage.
To understand how competitive it would be, we compare its economics to the 787, 767-300F, and A330-200F freighters.
Summary
- Airbus’s A330-900F would be a modest upgrade project, as all bits needed are in production today.
- The result would outcompete all present midrange freighters and give a 787 freighter a match in the market.
Airbus nears finding homes for Air Asia X, Aeroflot widebodies

By Scott Hamilton
April 11, 2022, © Leeham News: Airbus removed nearly all A330-900s from its backlog to AirAsia X, finally acknowledging what the industry knew for years: this deal was toast, even before the pandemic burnt it.
There are also A350-900s for Aeroflot that now no longer can be delivered.

Despite the widebody marketing being in the dumps, likely for another couple of years, don’t fret about these lost orders. According to market intelligence, Airbus has perhaps three campaigns for the A330neo that may jell within the new few weeks or months.
And the Aeroflot A350s may have a home sooner than anyone would think. Furthermore, some may wind up going to a customer with orders for the Boeing 787 that are in limbo because of the 18-month suspension of deliveries.
Furthermore, Airbus is quietly working to consolidate its dominance in the single-aisle market as the COVID pandemic continues to wind down and Boeing has challenges ramping up its 737 production—and certification of the 737-10 MAX by year-end seems slipping. The ramifications of this slip could be profound.
Summary
- Airbus lining up customers to take Air Asia X canceled A330-900s.
- Aeroflot A350s may find home soon, with a customer awaiting 787 deliveries.
- Boeing’s 737 production rate plans were affected by the China Eastern crash.
- China Eastern crash cause appears trending toward pilot suicide.
Pontifications: Catching up—DHC extends Dash 8 life; 737-10, 777X, A321XLR certifications
Every once in a while, it’s necessary to catch up on this and that….
By Scott Hamilton
April 11, 2022, © Leeham News: The announcement drew little notice because the topic wasn’t sexy. De Havilland Canada last week said that Norway’s Wideroe Airlines became the first operator to sign up to extend the service life of its Dash 8-100s from 120,000 cycles to 160,000 cycles. The carrier previously contracted to extend the life of the Dash 8 from 80,000 cycles to 120,000 cycles.
“Combined, our two Extended Service Programs add another 30 to 40+ years to the operational life of Dash 8-100 aircraft – that’s double the original service life of the aircraft,” DHC’s Robert Mobilio, Vice President Engineering, said in a statement.
The move is significant because there are no replacement aircraft in the 30-seat category. The market for airplanes this size is very small, and any replacement aircraft would likely be beyond the financial reach of many regional carriers. Extending the life of these airplanes—for an astonishing 30-40 years—is the only viable alternative.
DHC is separately evaluating hybrid technology, with engine maker Pratt & Whitney Canada, to make the Dash 8 series more environmentally friendly. A Dash 8-100 will be used for the hybrid-electric demonstrator.

By Bjorn Fehrm
April 8, 2022, ©. Leeham News: Last week, we discussed the architecture of a liquid hydrogen fuel system. We now start looking at the propulsion system of a hydrogen aircraft.
Before discussing how a propulsion system is done, we must understand what power requirements different airliner types have and the importance of these types in the market.

An A330neo freighter, should it happen?
Subscription Required
By Bjorn Fehrm
Introduction
April 7, 2022, © Leeham News: Last week, we started a discussion on what should be Airbus’ response to a 787 freighter. We have seen in a series of articles that the 787 freighter would beat the present A330 freighter, and the question is, will Airbus leave this segment to Boeing, or will it respond?
We look at what’s involved for Airbus to upgrade the present A330-200F to a neo freighter and what performance it would have compared to a 787 freighter.
Summary
- An upgrade of Airbus’ present A330-200F freighter to a neo variant based on the longer, more capable A330-900 would be a modest project for Airbus. All the special bits needed were developed for the A330-200F.
- The resulting A330-900F would be a competitive freighter, and as all needed parts are in serial production today, it could hit the market before a Boeing 787 freighter.
War in Ukraine: a local’s perspective
By Judson Rollins
April 6, 2022, © Leeham News: This week, LNA reports on a story outside our usual beat: an account of Russia’s invasion of Ukraine through the eyes of a local who watched tanks and explosions from her window.
Introduction
Source: Anna Kovalchuk
Three years ago, I spent several months on a consulting engagement in Kyiv, where I made a few local friends. I’ve been fortunate to stay in contact with some of them.
One of those friends is Anna Kovalchuk, a talent acquisition specialist for German pharmaceutical giant Bayer AG. Anna lived until last month in Irpin, Ukraine, a few miles from Antonov International Airport, previously home to several of Antonov Aircraft Company’s An-124 Ruslans and its recently destroyed An-225 Mriya. The airport and nearby suburbs including Irpin were the subject of intense fighting between Ukrainian and Russian forces since the invasion began on February 24 until just last week.
Anna and I have been in touch regularly since the war began. I visited her in Gdańsk, Poland, not long after she arrived, where she graciously agreed to share the story of her escape from fighting in her neighbourhood to a new life – ironically, a life she began a week earlier than planned due to the invasion.
Gdańsk is a quiet town of nearly 600,000 on the Baltic Sea. Although it was only a couple of weeks into Russia’s war with Ukraine, I saw few indications of the refugee influx that has overwhelmed so many other cities in Poland. However, there were numerous signs of support for Ukraine, including appeals on business doors for supplies ranging from canned food to clothing to small electronics. Read more
