March 10, 2026 — Boeing announced that Boeing 737 MAX deliveries delayed due to wiring flaws caused by small scratches on electrical wiring bundles from a machining error will require rework on a group of produced but undelivered 737 MAX aircraft, potentially slowing first-quarter deliveries while maintaining full-year targets of about 500 jets.
The company disclosed the issue on Tuesday, stating it has paused ticketing and deliveries temporarily to address the quality non-conformance discovered during production at its facilities. According to Boeing, the scratches occurred internally and do not affect military variants or in-service planes.
Details of the Wiring Issue
Boeing described the problem as “small scratches due to a machining error” on wiring bundles. Repairs are expected to take several days per aircraft.
“Our 737 program is performing rework on a group of airplanes to fix wires that have small scratches due to a machining error.”
Boeing spokesperson Katie Ringgold noted:
“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.”
The Federal Aviation Administration and customers have been informed, with no immediate comment from the FAA.
Delivery and Production Impact
Boeing 737 MAX deliveries delayed due to wiring flaws are anticipated to affect March and first-half totals, following strong February deliveries of 43-51 jets and three in early March. Production continues unaffected at 42 jets per month, with plans to rise to 47 later in 2026 and 63 long-term, including a new line at Everett, Washington.
“Production of new 737 Max airplanes continues at the existing rate… 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.”
The company reaffirmed its 2026 goal of at least 500 deliveries amid a backlog exceeding 6,100 orders, two-thirds for the 737 MAX.
Safety Assurances
An engineering analysis confirmed the scratches pose no immediate safety-of-flight issue.
“All in-service 737 MAX airplanes can continue to safely operate. If action is required for the in-service fleet, we will issue updates through our normal service bulletin process.”
Market Reaction
Boeing shares fell nearly 1% to 3.2% following the announcement, per Barron’s and Reuters. CEO Kelly Ortberg highlighted progress in the company’s turnaround.
Boeing 737 MAX deliveries delayed due to wiring flaws represent the latest quality hiccup, as covered by The New York Times, FlightGlobal, and CNBC. Aviation analysts on X echoed that fixes are quick and targets intact, as in this post.
