When documenting a major repair, which of the following is mandatory?

When documenting a major repair, including the narrative, it is essential to include the manufacturer's name. This is critical for several reasons. The manufacturer's name provides clear identification of the part or component that has been repaired, ensuring traceability and accountability throughout maintenance records. It also aids in verifying that any approved repair or alteration complies with the regulatory standards set forth by the manufacturer and the FAA.

While including additional information, such as the date of manufacture and model number, can certainly enhance the documentation, the mandatory requirement specifically highlights the importance of the manufacturer's name in establishing a complete and compliant record of major repairs. This assists regulatory authorities in tracking the lineage of repairs and ensures that maintenance personnel have access to accurate and relevant information regarding the parts used.
