For preventive maintenance, what must be entered into the aircraft 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. Date of maintenance only
• C. Cost of maintenance
• D. Vendor name

Answer: (A)

The key idea is that preventive maintenance records must show who approved the work and exactly what was done. The best entry includes the signature of the person approving the maintenance, their certificate number, and the kind of certificate they hold, along with a description of the work performed. This combination provides a clear, verifiable record of authority and scope, which is essential for airworthiness oversight and traceability. The date is typically included as well, but the crucial pieces are identifying the approver's credentials and detailing the maintenance performed. Entries that only note the date, or mention cost or vendor name, do not provide the necessary proof of who authorized the work or a clear description of the work done, so they don’t meet the documentation requirements.
