The U.S. National Transportation Safety Board reported that Boeing issued a service bulletin in 2011 warning airlines about a defective engine-bearing component on MD-11 freighters—years before the November 2025 UPS Flight 2976 crash in Louisville, Kentucky. That component had fractured on four previous aircraft, but Boeing deemed it non-critical and did not require mandatory fleetwide replacement. The bulletin recommended operators fit a redesigned bearing, yet carriers remained allowed to install the original part. Investigators found cracks in the bearing supports that went undetected until the ill-fated takeoff, when the left engine separated at 30 feet altitude, causing the loss of three crew and 12 ground fatalities. The NTSB’s preliminary findings raise questions about Boeing’s assessment of service bulletin implications and the adequacy of existing inspection intervals for aging MD-11 airframes.

Boeing delivered 160 commercial jets in the fourth quarter of 2025, lifting its full-year total to 600 aircraft—the highest annual delivery tally since 2018. The 737 family drove this result with 117 units handed over to customers in the quarter. On the defense side, the Defense, Space & Security division completed delivery of 37 platforms during the period, bringing its 2025 total to 131 units across Apache and Chinook helicopters, F-15 and F/A-18 fighters, KC-46 tankers and MH-139 transport helicopters. Management cited renewed assembly-line stability, tighter quality controls and an order backlog that supports a planned ramp to 84 737 MAX jets per month by the end of 2026.

Delta Air Lines placed its first direct order for up to 60 Boeing 787-10 Dreamliners, marking a strategic shift from its longstanding Airbus widebody fleet. The purchase comprises 30 firm deliveries and 30 options, with the new jets scheduled to enter service in the early 2030s. The 787-10 variant, seating up to 336 passengers and offering roughly 7,300-mile range, will replace aging 767s on transatlantic and South American routes. Delta President Glen Hauenstein highlighted the Dreamliner’s enhanced fuel efficiency, cargo capacity and premium-cabin flexibility as key drivers. The agreement further diversifies Boeing’s widebody backlog and reaffirms carrier confidence after past supply-chain and quality headwinds on the 787 program.

Boeing executives report that at a production rate of 84 737 MAX units per month, the program is already 97% sold out through the next 24 months. The recent Aviation Capital Group order for 50 additional MAX jets brought the lessor community’s cumulative orders to nearly 1,300 aircraft, representing one-fifth of the total MAX backlog. This high book-to-bill ratio and the absence of unplaced delivery slots underline robust global demand, supported by fleet renewals at major airlines and record commercial airline traffic levels returning to pre-pandemic volume. The production discipline in Renton and strong order visibility position Boeing to manage its supply chain more predictably and pursue incremental rate increases into 2027.
