Boeing Grounds 737 MAX Jets Over Wiring Glitch
11 Mar
Summary
- Scratched wiring found in new 737 MAX planes due to machining error.
- Boeing anticipates minor repair times, but deliveries are impacted.
- FAA is currently investigating the reported wiring problem.

Boeing is experiencing a new disruption in its 737 MAX production, with deliveries of some newly manufactured aircraft being postponed. The company identified scratched wiring, traced back to a machining error, in undelivered planes. A Boeing spokesperson indicated that repairs for each aircraft should take only a few days.
This issue introduces a delay in this month's overall plane deliveries. However, Boeing is maintaining its objective to deliver around 500 737 MAX planes to customers by the end of the year. The Federal Aviation Administration has confirmed it is looking into the matter, and Boeing's shares saw a slight decrease following the announcement.
The delivery delays complicate Boeing's efforts to assure regulators about its manufacturing improvements, especially after a mid-air incident in January 2024 led to increased scrutiny. Previously, the company had aimed to accelerate production, though some quality control metrics remained a concern.
Boeing delivered 43 narrow-body 737 jets in February, contributing to a total of 51 aircraft deliveries that month, the highest February figure since 2017. The company plans to increase 737 output by reopening a production line at its Everett, Washington, factory.
