Boeing is repairing 25 MAX jets as wire flaws halt deliveries

Boeing Co. (BA.N) has paused deliveries of some 737 MAX aircraft to address wiring flaws caused by a machining error, according to internal statements and industry reports. The company identified scratches on wiring in undelivered planes and traced the issue to production processes within its facilities, not suppliers according to internal statements. Affected aircraft are undergoing rework, with repairs expected to take several days per unit. Boeing emphasized that in-service 737 MAX jets remain safe to operate and that any required updates for flying aircraft will be communicated via standard service bulletins.

The issue is likely to delay first-quarter deliveries but is not expected to impact full-year targets for the 737 program, which aims for at least 500 deliveries in 2026. In February 2026, Boeing delivered 43 737 MAX planes, slightly higher than January's 37. However, the rework may slow March deliveries, with Aero Analysis Partners reporting only three 737 MAX deliveries as of March 5.

Boeing notified the Federal Aviation Administration and customers of the problem and confirmed it is not adjusting production rates for the 737 MAX during this period. The company's 737 lines in Renton, Washington, currently produce 42 aircraft monthly, with plans to expand capacity in Everett later this year. Separately, Boeing faces ongoing challenges with 787 Dreamliner deliveries, including seat certification delays, which constrained February output to three units.

The wiring issue adds to ongoing efforts by CEO Kelly Ortberg to stabilize operations and restore the company's reputation following past safety controversies. Boeing's shares traded mixed on March 13, reflecting broader market caution ahead of potential production updates.
