Final answer:
The AFTO used for maintaining a permanent history of significant maintenance actions on end items is AFTO 95. The reference 29517 does not relate to a maintenance form but to personnel actions, highlighting the importance of using the correct forms in the Air Force.
Step-by-step explanation:
The Air Force technical order (AFTO) used for maintaining a permanent history of significant maintenance actions on end items is the AFTO 95.
This technical order serves as the official record for documenting the life cycle of Air Force equipment, ensuring all maintenance actions, modifications, and significant events are tracked over the course of the equipment's service life.
In contrast, the reference number 29517 does not pertain to an AFTO form but represents a record related to personnel actions such as promotions, reductions, transfers, and casualties.
Therefore, it's crucial for Air Force personnel to use the correct form to maintain accurate historical data on Air Force equipment.
