Boeing has reported that 737 MAX aircraft deliveries could face delays during the first quarter of the year due to identified wiring faults.

Technical Details and Corrective Measures

The manufacturer identified a group of aircraft requiring rework due to the presence of small hairline scratches on cables, stemming from a machining error. Boeing has not specified whether these damages originated from an external supplier or the company’s internal processes.

In light of this discovery, the company has taken the following actions:

Regulatory Notification: The Federal Aviation Administration (FAA) and affected customers have been officially informed.
Operational Safety: The company assured that all 737 MAX aircraft currently in service can continue to operate safely.
Production Continuity: Production of new MAX models remains, for the time being, at the current rate of 42 units per month.

Expansion Plans and Production Targets

Despite this setback, Boeing maintains an ambitious growth outlook for its single-aisle program:

Short-term Increase: The company plans to raise the production rate to 47 aircraft per month by the end of this year.
New Infrastructure: This summer, the opening of a fourth 737 assembly line is anticipated at its Everett, Washington plant.
Long-term Vision: The ultimate goal is to reach a production cadence of 63 aircraft monthly in the coming years.

The announcement regarding the delays follows a positive month of February for the manufacturer. During that period, Boeing delivered a total of 51 aircraft, of which 43 were 737 MAX models. This figure represents the highest total for a February since 2018 and an increase over the 46 units delivered in January.

Boeing reaffirmed that it does not expect this technical issue to alter its annual target of delivering approximately 500 aircraft from the 737 family this year. Repair efforts will focus on rectifying the affected units prior to final delivery to ensure compliance with the quality standards required by the FAA and international operators.
