Which form is used to record historical maintenance activities?

The AFTO Form 95, known as the Aircraft Status Information, is specifically designed to document the historical maintenance activities of an aircraft. This form is crucial as it provides a comprehensive record of all maintenance actions that have been performed on the aircraft over its lifespan. Historical data captured on this form is vital for assessing the maintenance needs and overall reliability of the aircraft, aiding in any future maintenance decisions or inspections.

The other forms mentioned serve different purposes: AFTO Form 20 is utilized for documenting inspections and discrepancies, AFTO Form 106 is aimed at recording aircraft component history, while AFTO Form 501 is used for documenting modifications and retrofits. Each has its distinct role in the maintenance documentation system, but only AFTO Form 95 captures the historical maintenance activity comprehensively. This makes it the appropriate choice for the question regarding recording historical maintenance activities.
