After completing an FAA Form 337, what next step is required?

After completing an FAA Form 337, the next required step is to provide one signed copy to the owner. The purpose of Form 337 is to document major repairs or alterations made to an aircraft, and it is essential that the owner receives a copy for their records. This ensures they are informed about the modifications made to the aircraft, which may affect its maintenance, safety, and operational status.

Providing the owner with a signed copy also fulfills regulatory requirements, creating a clear and traceable record of the work that has been performed. The owner is responsible for ensuring that the form is retained as part of the aircraft's permanent records, which is crucial for future inspections or potential resale of the aircraft.

Although maintaining a digital copy, sending it to the FAA for approval, and filing it with general maintenance documents are actions that might be considered part of the overall management of the form, they do not fulfill the immediate necessary step of notifying the owner. The owner’s awareness and documentation are vital in the context of aircraft maintenance and ownership responsibilities.
