Sept. 12, 2024, © Leeham News: The International Association of Machinists (IAM) District 571 votes today on a contract proposal negotiated between union leadership and the management at Boeing (BA). It’s a critical vote for both parties.
The four-year contract calls for a 25% pay hike, a $3,000 signing bonus, an improved benefits package, and a commitment to build any future new aircraft in the Seattle area during the next four years.
Boeing yesterday issued a new Contract comparison sheet in advance of today’s vote: Boeing Contract Comparison_Fact_Sheet 9-11-24
Union workers can reject the offer, which must be approved with a 50%+1 majority. A second vote on a motion for strike action if the contract is turned down will also be on today’s ballot. A strike vote must be approved by a two-thirds majority. If this fails, the contract becomes adopted irrespective of the accept-or-reject vote. Boeing is desperate to avoid a shutdown as it faces pressure from customers, regulators, and suppliers who have endured one of the worst stretches in its history.
On Wednesday morning, hundreds of workers walked out of the Everett factory to rally against the contract. Engineers at the Renton factory were sent home because demonstrations there made it too noisy to work. They were told to work from home today,.
Leadership at the local previously indicated that they intended to demand a 40% raise for members, along with a seat on the board of directors, having gone through 16 years of giving concessions to management, as they were strong-armed in previous negotiations. Read more

September 12, 2024, © Leeham News: We examine the high-volume short-to-medium-range market and check whether a route previously reserved for the Airbus A330neo can be flown with a fleet of A321XLRs. At equal per-passenger operational costs, doubling the frequency is advantageous and can drive market growth, revenue, and margin.
After comparing the aircraft and their seating, we now use our Airliner Performance and Cost Model (APCM) to fly them on a Southeast Asia route and compare the operating costs.

Sept. 11, 2024, © Leeham News: GE Aerospace and Safran advance on the CFM RISE Open Fan engine with an overriding goal: “Our customers really want us to be hyper-focused on reliability and durability out of the gates.”
GE and Safran are developing a potentially game-changing engine and marketing it via the 50-50 joint venture, CFM International. The entry-into-service goal is 2035.
Customer demand for reliability and durability “out of the gates” is understandable. Engines produced by CFM, Pratt & Whitney and Rolls-Royce disappointed Airbus and Boeing customers operating the Airbus A320neo family, the Boeing 737 MAX and 787 and now the Airbus A350. Durability and/or technical issues plagued the CFM LEAP, Pratt & Whitney Geared Turbo Fan (GTF), Rolls-Royce Trent 1000 and now the RR Trent XWB-97. The giant GE9X engines on the Boeing 777X also suffered technical problems during the long, extended flight testing.
Operators protested as on-wing time fell short of promises. 787s, A220s, A320neos, and to a lesser extent Embraer E195-E2s were grounded as engines components failed, MRO shops backed up (displacing routine overhaul requirements on older engines) and new-production engines were diverted to replace those on grounded aircraft.
The CFM LEAP, GE and Safran promise, will provide a 20% reduction in fuel consumption and emissions. But the radical technology of an Open Fan gives airlines, lessors and even Boeing pause.
GE and Safran say they are progressing through development of the 35,000+ lb thrust engine but there is a lot of work to do to make it ready for service and give customers confidence.

Sept. 11, 2024, © Leeham News: The replacement for the Airbus A320neo family should be 25% more efficient, says CEO Guillaume Faury.
“The priority for the next generation of single line, the one that will replace the very successful A320 family, will be to reduce the fuel burn by around 25%,” he said. Further reduction in carbon emissions has to come from the use of decarbonized fuel. This is primarily sustainable aviation fuel. “This is something we’re going to achieve working on the propulsion system,” he said.
Faury made his remarks during the annual US Chamber of Commerce Aviation Summit in Washington (DC).
Faury said that the CFM RISE Open Fan engine appears, so far, to be the best hope for a new engine. “It’s been very interesting to see the RISE engine as a successor of the LEAP to continue to improve fuel efficiency. Part will come from the propulsion system, as usual, and a large part will come as well from the plane itself.”

Sept. 10, 2024, © Leeham News: Boeing’s touch labor union, the International Association of Machinists and Aerospace workers District 751 (IAM) votes in two days on a new labor contract.
Although a Tentative Agreement was reached Sunday and union leadership endorsed it, getting 50%+1 vote to ratify the contract appears in trouble. A concurrent strike vote requires a two-thirds majority for a walk out, and there is split opinion whether this high threshold can be met.
This will be a hard sell for IAM leadership. The deal makes progress in the areas IAM members identified as priorities, but falls short of the union’s stated goals in most of them:

Sept. 8, 2024, © Leeham News: In a development that is contrary to all expectations, The Boeing Co. and the IAM 751 labor union reached a tentative agreement this morning on a new four-year contract.
IAM members, who assemble Boeing’s airplanes in the great Seattle area, get a 25% raise over the life of the contract; the union asked for 40%. The value goes up to 33% in “wage growth” when the wage increases, and “progression” are calculated. Certain pay grades did get a 42.3% increase, the IAM said.
There is a lump sum payment of $3,000 and Boeing’s 401(k) contribution increases up to $4,160 per employee per year. The union asked for a return to a defined benefit plan, which was probably a non-starter. Lower costs for medical care were agreed.
Boeing committed to build the next new airplane in the Seattle area. A Boeing spokesperson did not have details whether this would be in Renton, where 737s are built, or Everett, where widebody aircraft are currently assembled. Boeing also committed to keep the current 737, 767 and 777X production in Puget Sound.
The union also wanted a seat on the Boeing Board of Directors. Neither side referred to the seat in their information released today, so it appears this may not have been agreed. The Boeing spokesperson had no information on this and the IAM wasn’t immediately available to comment.
The IAM leadership unanimously recommends approval of the contract. The vote is set for this Thursday.

We have covered the parts of an engine that involve challenging technology and which decide its reliability (dispatch consistency) and durability (time on wing). Now, we discuss why modern engine design is more challenging regarding these parameters than airframe design.

Analysis
Sept. 5, 2024, © Leeham News: There seems to be quite an expectation that there will be a strike by Boeing’s touch labor union, the IAM walkout at Boeing this contract cycle. The costs associated with a strike are well understood. Crippled cash flow, upset customers, and stock price losses not counting the damage to the companies in Puget Sound that built much of their business models on Boeing worker’s paychecks. It’s never a good thing to sustain a strike of any duration because the disruptive effects can last for years.
The last time the IAM struck was in 2008, for 57 days. The strike cost Boeing billions of dollars in lost revenue, much of which was made up in the following years. The ill-will generated by the strike affected customers. Management-labor relations remain strained to this day. Union leadership is determined to recover previous givebacks in wages and benefits. They want a seat on the Board of Directors, a role in improving Boeing’s safety culture, and a guarantee that the next airplane will be assembled in Puget Sound.
Talks remain far apart, according to the union. Boeing says progress is being made. A strike seems likely at this stage.
Boeing is clear about a strike potential. In a message last week to employees, Boeing said:
Does Boeing want a strike so it can stabilize production or allow time for the supply chain to recover?
Absolutely not. Any work stoppage, whether days, weeks or months, would disrupt our production system, supply chain and most importantly, our customers. When Boeing cannot deliver airplanes as scheduled, customers question our reliability. A strike would only help the competition and hurt our suppliers.
What is Boeing supposed to do if the IAM walks out? The usual answer is sweeping and cleaning and trying to deliver whatever you can sneak out the door to keep the money coming in. It is never a very effective way to operate.
Here are some points to ponder if the strike occurs and Boeing production shuts down.
