When do you turn the purchase tapes end for end on the BAK-12 arresting system?

Turning the purchase tapes end for end on the BAK-12 arresting system is crucial for maintaining the system's functionality and prolonging the life of the equipment. This practice is typically performed every 24 months. The reason for this specific interval is to ensure even wear on the tapes, as they are subjected to significant stress during operation. By flipping them, the wear patterns are balanced, which helps maintain proper tension and reduces the risk of failure due to uneven degradation.

Regular maintenance schedules like this one are critical for safety and performance, especially in systems like arresting gear that are essential for landing aircraft safely. Adhering to the 24-month schedule ensures that any potential issues are addressed proactively while also ensuring compliance with operational standards and guidelines.
