How long must a flight instructor keep a copy of all student pilot endorsements?

A flight instructor is required to maintain a copy of all student pilot endorsements for a period of three years. This requirement helps ensure that there is proper documentation of the student's training and qualifications, which is crucial for regulatory compliance and maintaining safety standards. The three-year retention period allows for sufficient oversight of the student's progress and the instructor's adherence to the necessary legal and educational responsibilities.

The reasoning behind this timeframe is to align with various regulatory practices and to provide a clear history of the endorsements given, which can be critical in case of disputes or questions regarding a student's training and readiness to solo or take further examinations. Beyond this duration, records may become less relevant as students progress and complete their training, but retaining them for three years ensures that instructors maintain accountability and transparency in their mentorship of student pilots.
