During which inspection is the proper entry in maintenance records crucial?

Proper entries in maintenance records are crucial during both annual and 100-hour inspections because these inspections are mandated by the Federal Aviation Administration (FAA) regulations for ensuring continued airworthiness of an aircraft.

For annual inspections, the regulations specify that an aircraft must undergo a comprehensive inspection every 12 calendar months. Proper documentation is necessary not only for compliance but also to provide a clear history of maintenance activities and any discrepancies found during the inspection.

Similarly, a 100-hour inspection is required for aircraft that are used for hire or flight training, requiring documentation that details the inspection completed and any maintenance performed or needed. This meticulous record-keeping ensures traceability and accountability for the aircraft's maintenance status.

Both types of inspections require adequate documentation to track whether all necessary tasks were completed and to identify any potential issues. This helps maintain safety standards and ensures that the aircraft remains airworthy. Having complete and accurate maintenance records is essential for compliance with FAA regulations and for the safety of flight operations.
