What is the purpose of torque specifications in aircraft maintenance?

The purpose of torque specifications in aircraft maintenance is crucial for ensuring the safety and reliability of aircraft components. Torque specifications define the precise amount of rotational force that must be applied when fastening bolts and other components. This is important because improper torque can lead to either over-tightening or under-tightening, both of which can compromise the integrity of the structure and systems of the aircraft.

When fasteners are tightened to the manufacturer's required specifications, it ensures that components are secured properly and function as intended. This is particularly vital in aviation, where the performance of each part is critical to the overall safety and operation of the aircraft.

For example, if a critical component such as a propeller or wing bolt is not torqued correctly, it can lead to mechanical failure during operation, which poses significant safety risks. This is why adherence to torque specifications is a fundamental part of aviation maintenance practices.
