If more space is needed for a work description on FAA Form 337, what information should be included on the attached sheet(s) in addition to the rest of the work description?

• A. The inspector's license number
• B. The date the work was accomplished
• C. Aircraft nationality and registration mark, and the date the work was accomplished
• D. The manufacturer's part number

Answer: (C)

When you need more space for a work description on FAA Form 337, the attached sheet should include the aircraft’s nationality and registration marks (the tail number) and the date the work was accomplished. This pairing ties the extended description to a specific airplane and pins the completion date in the aircraft’s maintenance history, which is essential for proper recordkeeping and future reference. The inspector’s license number isn’t part of the required attachment, and a date alone wouldn’t identify the airframe. A manufacturer’s part number isn’t needed for this purpose, since it doesn’t uniquely identify the aircraft or the specific alteration.
