How should copies of FAA Form 337 be distributed after a major repair is completed?

When a major repair is completed, the proper distribution of FAA Form 337 is crucial for maintaining accurate aircraft records and compliance with regulatory requirements. The correct approach is to process the form such that one copy is retained in the aircraft's records, and the other copy must be submitted to the FAA District Office within 48 hours.

This practice ensures that there is an official record of the repair in both the aircraft’s documentation, which is important for future maintenance and inspections, and with the FAA, which enables the agency to maintain accurate oversight of maintenance activities performed on aircraft.

Submitting the form to the FAA helps in providing a complete maintenance history for the aircraft, which is essential for regulatory compliance and maintaining the airworthiness of the aircraft. Additionally, it allows the FAA to track repairs and modifications in the aviation system more broadly, leading to improved safety and oversight.

Though the answer selected suggests that both copies return to the person who performed the work, this approach does not meet regulatory requirements and does not contribute to the overall maintenance documentation that is vital for future reference and inspections.
