Who is responsible for the upkeep of the required maintenance records for an aircraft?

The aircraft owner is fundamentally responsible for the upkeep of the required maintenance records for an aircraft. This responsibility includes ensuring that all maintenance performed is documented accurately and retained for the appropriate length of time as mandated by aviation regulations. The owner must keep a detailed and accurate log of maintenance history, modifications, and repairs to ensure compliance with safety regulations and standards. This record-keeping is crucial not only for legal purposes but also for maintaining the overall airworthiness of the aircraft.

While certified mechanics, pilots, and maintenance facilities play important roles in the maintenance process, their responsibilities are typically more centered around execution and direct oversight of repairs and checks rather than the ownership of the record-keeping process. Mechanics may document their work, and pilots are required to log their flights and any discrepancies, but the ultimate responsibility lies with the aircraft owner to ensure that all needed records are maintained properly.
