For how long must an aircraft owner maintain the records of a 100-hour inspection?

The correct response is based on the regulatory requirements outlined in the Federal Aviation Regulations (FARs). Specifically, for a 100-hour inspection, the aircraft owner is required to maintain records of the work performed. This includes documentation that verifies the inspection took place and any maintenance or alterations made to the aircraft.

The appropriate retention timeframe is until the work is superseded or for one year after the inspection. This means that if another inspection occurs that changes the previous work or if the aircraft is sold, the records need to reflect the most current status of the aircraft. Keeping these records for one year after the inspection is crucial for maintenance tracking, compliance with FAA regulations, and ensuring that all necessary logs are available for review if needed.

While some options suggest longer retention periods or conditions that don't align with FAR requirements, the specified timeframe effectively balances both regulatory compliance and the practical aspects of aircraft ownership and maintenance. Understanding these maintenance record-keeping requirements is essential for ensuring safety and legality in aviation operations.
