Which document is used to authorize and record maintenance tasks for a vehicle or equipment?

• A. Trailer status
• B. Work order
• C. MFT
• D. Flight hours of pgm

Answer: (B)

A work order is the control document that authorizes and records maintenance actions on a vehicle or equipment. It details what needs to be done, which asset is involved, the planned steps, required parts and tools, safety considerations, and who will perform the work. It must be approved before maintenance begins and then updated after completion with what was actually done, labor hours, parts used, and the technician’s sign-off. This creates a clear, traceable history for maintenance planning, cost tracking, and compliance.

Other options don’t provide that formal authorization and complete task-recording trail. Trailer status is just a snapshot of current condition or location, not a formal work authorization or record. MFT may refer to a type of form in some contexts but isn’t the standard document used to authorize and document maintenance tasks. Flight hours of a program track usage, not the maintenance actions performed.
