Air India Flight 171 Preliminary Crash Report Is Unclear Regarding Pilot Actions
By Bjorn Fehrm
July 11, 2025, © Leeham News: India’s Aircraft Accident Investigation Bureau has issued the preliminary report of the crash of Flight 171.
The report indicates that the aircraft and flight crew were fit for flight and that the pilots were experienced, with the Captain having a total of 15,638 flight hours, including 8,596 on type, and the First Officer having 3,403 flight hours, with 1,128 on type.
The report documents the technical registration of the engine’s Fuel Cutoff switches, which transition from RUN to CUTOFF, remain at CUTOFF for 10 seconds, and then return to RUN. By then, the engine cores have slowed down below flight idle, with the engines delivering almost no thrust.
Bjorn’s Corner: Air Transport’s route to 2050. Part 30.

July 11, 2025, ©. Leeham News: We feature a Corner series on the state of actions to mitigate the global warming impact from Air Transport. We try to understand why different developments have been slow.
In the last Corner, we correlated the growth of airliners between 2024 and 2050 and the growth in Greenhouse gas emissions of CO2 and NOx that would result. We also calculated the increase in warming from contrails based on the traffic increase by 2050. The results are in Figure 1.
We also discussed that the warming effects of CO2 are undisputed, whereas the impact of NOx and contrails is less mature in its complicated effects research. The performed research has a lowest and a highest warming probability. We will now do an “acid test” and see what their impact is when we apply their lowest probable effect on global warming.

July 10, 2025, © Leeham News: It’s official: Lars Wagner becomes CEO of Airbus Commercial Aircraft on Jan. 1. He will succeed current CEO Christian Scherer, who will retire after 40 years at Airbus.
Word of Wagner’s appointment leaked months ago.

Wagner joins Airbus on Nov. 1 to begin a two-month transition. He is currently the CEO of MTU Aero Engines, a position he assumed in 2023. He joined MTU in 2015. Before that, he held various positions at Airbus. He is an engineer.
Wagner’s appointment may cast a question over GE Aerospace’s campaign with Airbus to choose the RISE Open Fan engine for the latter’s new single aisle aircraft intended to replace the A320neo family.
During the Paris Air Show last month, Airbus Group CEO Guillaume Faury said Airbus plans to decide on the engine to be selected for the A3XX around 2027-2028. A program launch target is 2030 with an entry-into-service target of 2038.
Embraer E2: Where will the orders come from?

By Karl Sinclair
July 10, 2025, © Leeham News: At a subdued Paris Air Show, Brazilian aircraft manufacturer Embraer announced a firm order from US regional carrier SkyWest Airlines for 60 E175-E1 commercial aircraft, with purchase rights adding 50 planes to the order.

This brings the total SkyWest backlog to 74 aircraft, for a total backlog of 220 E1 jets for the variant; 211 of those aircraft are for American carriers.
While the recent SkyWest order is undoubtedly welcome news, the problem is that the rest of the commercial aircraft division is selling and producing the follow-on variant, the Embraer E2 line.
The smallest variant of the E2 family, the E-175 E2, was placed on hold by the company until 2027-2028. This was due to the inability of American carriers to utilize the aircraft in service, resulting from the Scope Clauses with the various pilots’ unions. SkyWest once had a conditional order for 100 E175-E2s. The condition was that the unions would alter the Scope Clause restriction on the aircraft’s weight. The E2 exceeds the allowed weight by a few thousand pounds. The E1 complies.
Scope caps the maximum takeoff weight of an aircraft at 86,000 lbs, or 76 seats. The heavier and more fuel-efficient Pratt & Whitney geared-turbofan engines powering the type put the variant out of reach of US operators.
The commercial aviation industry is undergoing a transformation.
Carriers are opting for larger variants in a segment, as evidenced by the shift in orders at Airbus, away from the A320 to the larger A321 variant, and at Embraer, where the E170 is no longer in production. The dominant aircraft is the largest E195-E2, which accounts for 81% of all orders, compared to 9% previously.
US Transpo Secretary supports zero tariffs on aerospace, but change isn’t assured

By Scott Hamilton
July 7, 2025, © Leeham News: US Transportation Secretary Sean Duffy wants to return to aerospace’s zero-tariff agreement, dating to 1979, but cautioned that doing so requires a larger trade agreement between party governments.
Currently, the US has a minimum 10% to 25% tariff on aerospace imports from the European Union and Canada, with much higher fees in some cases. The EU is prepared to impose reciprocal tariffs on the US.
Tariffs have major implications for Airbus and Boeing. Although Airbus assembles A220s and A320/321s at its US Mobile (AL) plant, fuselages, wings and other components are imported into the US from Canada (A220s) and the EU (A320/321s).
Boeing exports planes to the EU, which includes 28 countries. Boeing has more exposure than Airbus.
Components imported by Airbus or Boeing for inclusion in the airplanes are also subject to tariffs.
A Boeing spokesperson told LNA that it can recapture tariffs on important components that are on aircraft subsequently exported. But this ignores the overarching tariffs the EU may apply to the completed airplane.

In advance of the Paris Air Show, Airbus said that it’s going to adjust to US-imposed tariffs.
Responding to a question if it “made sense” for the Mobile plant to assemble A220s and A320/321s at the present rate given the impact of the tax, Christian Scherer said there will be no change. Airbus will live with the situation as it evolves. Scherer is the CEO of Airbus’s commercial operations.

July 4, 2025, ©. Leeham News: We feature a Corner series on the state of actions to mitigate the global warming impact from Air Transport. We try to understand why different developments have been slow.
In the last Corner, we wanted to understand the relationship between Greenhouse gas emissions of CO2 and NOx and the effect of global warming from contrails. After some iterations, we arrived at the comparison shown in Figure 1, where we compare different warming effects using CO2 and CO2e (CO2 equivalents, i.e. the same warming effect as CO2).

Does an A220-500 need a new wing and engines? Part 4.

July 3, 2025, © Leeham News: We are writing an article series about stretching the A220 to a capacity in the A320neo range. The idea is to replace the A320neo over time, making room in the A320/321 production lines for more A321s and extending the A220 family with a larger variant.
We can increase the capacity to that of the A320neo by stretching the A220 fuselage. The next discussion was about how much we could increase the Maximum Takeoff Weight (MTOW) to accommodate more passengers and additional fuel, thereby maintaining the A220-300 range with a longer, heavier, and, therefore, draggier aircraft. We would need to find wing lift improvements and more thrust to keep the field performance close to the A220-300.
We now utilize the Leeham Aircraft Performance and Cost Model (APCM) to evaluate various changes to an A220-500 to optimize its performance.

Summary:
- An A220-500 can be designed to have close to the same fuel seat-mile economics as the A320neo. Our article series explains why beating the A320neo would be a challenge.
- It also looks into what a CFM LEAP-engined A220-500 would look like and how it would perform.
GE testing of giant GE9X engine aims for maturity at entry into service

June 30, 2025, © Leeham News: GE Aerospace developed a huge engine for the Boeing 777X, the most powerful engine ever created. The GE9X tops out at 115,000 lbs of thrust.

It’s had its development challenges. The 777-9, the first of the X family, was supposed to enter service in early 2020. Technical issues with the GE9X required removal of the engines from the test airplanes and a return to GE for fixes. This delayed flight testing by nine months. By then, certification of the 777X got caught up in the Boeing 737 MAX crisis; the 777X still is awaiting certification, which parties hope will come this year. Deliveries are now expected to begin next year.
Tim Clark, the president of Emirates Airline, has 205 Xs on order, more than any other customer, out of 521 in total. He’s publicly complained about the initial test results of the GE9X and demanded engine maturity before he’ll accept delivery.
GE has used the six year delay in the program to attempt to satisfy this demand.

June 27, 2025, ©. Leeham News: We do a Corner series about the state of developments to improve the emission situation for Air Transport. We try to understand why development has been slow.
We have explored various methods to mitigate global warming throughout the series. Over the last few weeks, we have summarized the practical results we can expect from the different alternatives available to reduce global warming in air transport. We looked at the following:
- Alternative, lower-emission propulsion technologies.
- The industry’s typical improvement in fuel consumption over time.
- The improvements that SAF can offer by 2050.
- The different Emission Trading Schemes (ETS) that exist globally.
- And finally, what warming contrail reductions can achieve.
We have summarized what the first four actions can achieve by 2050 and presented the results in a table, Figure 1. Now we add what global warming contrail avoidance can do.

Parent agency, FAA often at odds as politics outweighs safety

By Colleen Mondor
June 26, 2025, © Leeham News: On March 12, 2019, then-Secretary of Transportation Elaine Chao and her staff flew from Texas to Washington (DC) on a Southwest Airlines 737 MAX. It was two days after the crash of Ethiopian Airlines flight 302, the second devastating accident involving the 737 MAX.
In taking the flight, Chao showed not only her support for Boeing and Southwest, but even more so the Federal Aviation Administration (FAA), which steadfastly refused to ground the aircraft. As the pressure mounted, the agency stressed the importance of its methodical data-gathering process, which had begun months earlier with the October crash of Lion Air.
Chao also reassured the public, telling reporters “I want people to be assured that we take these accidents very seriously. We are reviewing them very carefully.” The day after her flight, President Trump announced that after conversations with Chao, the CEO of Boeing and Dan Elwell, the FAA’s acting administrator, his administration was grounding the aircraft. Elwell told reporters later that day, however, that the decision rested with the FAA. “So the decision is an emergency order to ground the airplanes,” he said, “and that is authority rested in the FAA with me.”
Chao’s flight centered her in yet another chapter of the ongoing saga between the Department of Transportation (DOT) and FAA. This was familiar territory for DOT which, since the FAA lost its independence in 1967, has often portrayed itself as the crucial, agent of flight safety in the U.S.
The most recent example was when current transportation secretary Sean Duffy captured media attention after the January 29 midair collision over Reagan National Airport. The FAA, which again had an acting Administrator, was relegated to secondary sound bites as Duffy declared, “We are going to take responsibility at the Department of Transportation and the FAA to make sure we have the reforms…to make sure that these mistakes do not happen again and again.”
