For a preventative maintenance event, which information must be documented in the maintenance records?

• A. The signature, certificate number, and kind of certificate held by the person approving the work and a description of the work
• B. The date of the maintenance only
• C. The airframe serial number
• D. The reason for maintenance

Answer: (A)

Documentation must capture who approved the work and exactly what was done. The key items are the signature of the person approving the maintenance, their certificate number, and the kind of certificate they hold, together with a description of the work performed. This creates a clear record showing that an authorized individual reviewed and approved the preventive maintenance and exactly what actions were completed.

A simple date wouldn’t identify who approved or what work was done. The airframe serial number identifies the aircraft but doesn’t describe the maintenance action. The reason for maintenance isn’t the required record of what was actually performed, so it doesn’t provide the necessary traceability.
