Earnings: Pay closer attention to the supply chain than to the OEMs

Jan. 23, 2025, © Leeham News: Earnings season begins today. Among the companies followed by LNA, GE Aerospace and Hexcel report today. RTX and Boeing report next week. ATI and Spirit AeroSystems follow the week after. Other suppliers follow then.
Airbus doesn’t report until Feb. 20. Rolls-Royce reports on Feb. 27.
The manufacturers draw the headlines, but LNA found long ago that the supply chain often provides better information to draw conclusions about the future than listening to the OEMs. All it takes is one supplier to fall down on the job to muck up the works for the OEMs.
That’s not to say listening to the OEMs is not important. Clearly, it is. But there’s just no getting around it: the credibility of many of the OEMs is damaged. Airbus hasn’t hit its production ramp up targets in years. Quality control suffers. And deliveries are consistently late.
Steven Udvar-Hazy, executive chairman of the board for Air Lease Corp, says that every single Airbus aircraft, 250 of them, has been late since 2017. That’s long before the pandemic began in March 2020, which caused such disruption continuing to this day. Airbus was still delivering A320ceos during 2017 and 2018, which didn’t have engine issues.
Boeing’s credibility speaks for itself. It doesn’t matter that it has a new CEO. Until Boeing starts performing, anything it currently says is hope, not performance. Post-strike delivery recovery will be an important indicator of Boeing’s performance in the essentially truncated fourth quarter and January.
Suppliers often discuss information on their earnings calls that provides a better understanding of production rates at the OEMs and where downstream issues are or are emerging.
2025 remains another year for recovery in commercial aerospace

Jan. 6, 2025, © Leeham News: Don’t look for any dramatic new product launches in 2025.
Nor should you expect any dramatic news, absent global upheaval of some kind.
This year is going to be yet another year dominated by recovery. Recovery from the COVID-19 pandemic, which officially ended in 2022. Recovery by the supply chain. Recovery for Pratt & Whitney’s nearly decade-long problems with its Pure Power GTF engines supplying the Airbus A220, A320 family and Embraer E2 jets. Recovery by Airbus from its production and delivery delays. Recovery by Boeing from its series of self-inflicted crises, now beginning the sixth year.
There is just no getting around the fact that the commercial aerospace industry isn’t a smooth-running industry. It’s a long way from 2018, when all sectors were running smoothly. There is still a long way to go to recovery.
Here’s LNA’s take on what’s to come this year.
RTX, P&W parent, posts strong 3Q results
By Scott Hamilton
Oct. 22, 2024, © Leeham News: RTX Corp, the parent of troubled engine maker Pratt & Whitney, posted strong financial results for the third quarter today.
PW continues to struggle with replacing engines plagued by technical defects that have grounded nearly 600 Airbus A320neos worldwide. But year-over-year financial results are markedly improved.
Another subsidiary, Collins Aerospace, which makes a variety of components and interiors, reported higher results YOY.
RTX reported $20.1bn in revenues (+6% YOY)m operating cash flow of $2.5bn, free cash flow of $2bn, and returned $1.1bn of capital to shareholders. Net income was $1.472bn vs a loss of $984m in the prior year.
PW reported $7.2bn in revenue for the period vs a mere $926m in 3Q2023. The operating profit was $557m vs a loss of $2.48bn. Despite all the costs taken against the Geared Turbo Fan engines as PW struggles to replace a defective powder on a large installed fleet, aftermarket maintenance, repair and overhaul work drive the YOY improvements on the commercial side. The defense side of PW also saw a 20% increase in revenues.
Collins is hampered by delays in its interiors division, but revenues were up 7% YOY, largely through a 14% increase in components sales to the military. The commercial aftermarket was up 9%. Collins reported an operating profit of just over $1bn on sales of $7.07bn.
Despite these positive results, investment bank Goldman Sachs reported the results were below consensus.
“Segment Earnings Before Interest and Taxes (EBIT) is below driven by the Collins margin. Revenue is ahead at Pratt, and slightly below at Collins and Raytheon. EBIT is ahead at Pratt and Raytheon and below at Collins. Segment EBIT margin of 11.4% is below implied consensus at 11.9%,” Goldman wrote.
Bjorn’s Corner: New engine development. Part 28. Wrapup.
By Bjorn Fehrm
October 11, 2024, ©. Leeham News: We have done an article series on why engine development takes longer than airframe development. Part of the reason is that advancements in engine technology can deliver considerably higher fuel consumption reductions than airframe advancements.
The change of engines for the A320 series and 737 MAX delivered a 15% improvement in engine efficiency. In contrast, the airframe improvement was less than half, mainly by stacking cabin seats closer together.

Bjorn’s Corner: New engine development. Part 25. New versus old, CFM56 vs. LEAP

September 20, 2024, ©. Leeham News: We do an article series about engine development and why it has longer timelines than airframe development. It also carries larger risks of product maturity problems when it enters service than the airframe of an airliner.
In our look at examples of recent developments with problems and these put in a historical perspective, we compare the CFM56 to the LEAP, comparing their reliability and durability.

We have covered the engine’s different parts and their technology challenges. We now look at some examples of recent developments with problems and put them in a historical perspective.

We reached the turbine part on our way through the engine, where we last looked at high-pressure turbine temperatures. It’s the most stressed part of the engine and, in most cases, decides its durability. To understand why, we look closer at turbine technologies.

August 2, 2024, ©. Leeham News: We do an article series about engine development. The aim is to understand why engine development now has longer timelines than airframe development and carries larger risks of product maturity problems.
To understand why engine development has become a challenging task, we need to understand engine fundamentals and the technologies used for these fundamentals.
We have covered the problem areas of (Figure 1) compression in the compressor and combustion, with its requirements on low Soot and NOx emissions. Now we look at how combustors are designed to achieve such low emissions.

To understand why engine development has become a challenging task, we need to understand engine fundamentals and the technologies used for these fundamentals.
We have covered the problem areas of a compressor and how these achieve power-to-air-pressure conversion efficiencies of over 90% by using advanced 3D airflow modeling. Now, we look at the users of the air from the engin’s compressor.

July 11, 2024, © Leeham News: We are comparing the Airbus a321XLR to the Boeing 757 to understand to what extent it can replace the 757 on the longer routes it operates for major airlines like United, American, and Delta.
We have looked at the development and operational history of the aircraft, their Apples-to-Apples capacity and range. Now, we use Leeham’s Aircraft Performance and Cost Model (APCM) to compare the operational costs of the aircraft.
Summary:
- The Boeing 757-200 has the same passenger capacity as the A321LR/XLR and a larger cargo capacity.
- Its range can compete with the A321LR but not the XLR. Both beat the 757 on operational economics.
