Maintenance records for UAS should include part numbers, service times and dates, and the _____

The maintenance records for Unmanned Aircraft Systems (UAS) should include a description of the problem encountered. This information is crucial as it provides insight into any issues that may have arisen during operation, allowing for better troubleshooting and understanding of the aircraft's performance. Documenting the problem ensures that maintenance personnel can track recurring issues, implement appropriate corrective actions, and enhance safety protocols moving forward.

While details such as part numbers, service times, dates, and manufacturer information are important for record-keeping and parts replacement, articulating the specific problems encountered gives context to the maintenance tasks performed and informs future operational decisions. It contributes to a comprehensive maintenance history that serves as a valuable resource for both current operations and future reference.
