March 10, 2026 — Renton, Washington — Boeing has paused deliveries of certain undelivered 737 MAX aircraft after discovering small scratches on wiring bundles caused by an internal machining error during production, a development that will slow first-quarter shipments but not affect full-year goals.
The Boeing 737 MAX wiring issue halts deliveries of affected produced-but-undelivered jets as the company performs rework to ensure quality standards are met. Boeing informed the FAA and customers, confirming no safety impact on in-service aircraft.
Cause and Scope
The scratches stem from a machining error within Boeing facilities, not suppliers. The exact number of affected aircraft remains undetermined, with rework expected to take several days per jet. Recent deliveries included 43 737 MAX in February and three in March before a halt on March 5, per Aviation Week.
Boeing 737 program Vice President Katie Ringgold stated at ISTAT Americas:
“We paused ticketing and deliveries as we work through this issue.”
“There is going to be disruption [for] the next few days. It will take several days to resolve, not weeks.”
Company Response
Production continues at 42 jets per month, with plans to reach 47 later in 2026 and open a fourth line in Everett. Full-year target of at least 500 deliveries stands firm.
Boeing said:
“Our 737 programme is performing rework on a group of airplanes to fix wires that have small scratches due to a machining error. This ensures they meet our quality standards before the airplanes are delivered.”
“We expect some near-term delivery delays that may affect our deliveries in the first quarter. But given the rework timeline, we do not currently expect this issue to impact our year-end delivery total.”
All in-service 737 MAX can operate safely, with service bulletins if needed later.
Broader Context
