Boeing is experiencing delivery delays for some first-quarter aircraft due to wiring damage issues on the 737 MAX passenger jet, while maintaining production at 42 aircraft per month. The CEO is working to improve manufacturing quality and repair the brand's image, with plans to increase output to 47 aircraft later, and expects this will not affect the 500-delivery target.

IT House, March 11 — According to Reuters, on Tuesday local time, Boeing announced that due to wiring scratch issues, some deliveries of the 737 MAX narrow-body aircraft may be delayed in the first quarter. In recent years, Boeing has faced ongoing problems, and this time, new manufacturing setbacks have emerged. CEO Kelly Ortberg is working to improve manufacturing quality and restore Boeing’s brand image.

Boeing explained that the 737 project team is reworking a batch of aircraft. Errors occurred during machining, causing small scratches on some wires, which require reprocessing. Meanwhile, the production pace of the 737 MAX remains unchanged, with a current monthly output of 42 aircraft.

After the announcement, Boeing’s stock price fell nearly 1% during Tuesday afternoon trading.

Boeing also stated that it plans to increase monthly production to 47 aircraft later this year. This summer, the company will activate a fourth 737 assembly line at the Everett plant in Washington state. In the coming years, the monthly production target for the 737 series is 63 aircraft.

Regarding the source of the wire scratches, Boeing did not specify whether it was a supplier issue or an internal manufacturing problem. The company has notified the Federal Aviation Administration (FAA) and relevant customers, but the FAA has not responded yet.

Boeing also emphasized that all operational 737 MAX aircraft remain safe to fly. Based on current assessments, this issue is not expected to affect the delivery target of approximately 500 737 aircraft this year.

IT House learned from the report that Boeing also released February delivery data. The company delivered a total of 51 aircraft that month, the highest since 2018 for the same period, up from 46 in January. Among the aircraft delivered that month, 43 were 737 MAX aircraft.
