What documentation is required after a minor repair on a certificated aircraft?

After a minor repair on a certificated aircraft, an entry in the maintenance record is required as a principal element of regulatory compliance. This documentation serves to record the details of the work performed, including the date of the repair, the nature of the work, and who completed the repair, ensuring a comprehensive maintenance history. This is essential for maintaining the aircraft's airworthiness and for the potential review by regulatory authorities during inspections.

While FAA Form 337 is typically required for major repairs and alterations, it is not necessary for minor repairs, which is why it is not the correct answer in this context. Similarly, a weight and balance report is usually associated with significant changes that affect the aircraft's center of gravity and is not mandated for minor repairs. A notice to the local aviation authority is also unnecessary for minor repairs, as regular documentation in the maintenance records suffices to meet compliance requirements. Thus, the focus on maintenance record entries reflects both regulatory standards and best practices in aircraft maintenance management.
