Fatigue Failure

Fatigue Failure

Fatigue Failure – Fatigue failure of metal components is by far the  most common type of the failure of aircraft components. Fatigue Failure is defined as the progressive and localized structural damage that occurs when a material is subjected to repeated or fluctuating loads (cyclic loading). The maximum stress values are less than the ultimate [...]

Aircraft Certification Office (ACO)

Aircraft Certification Office (ACO) is the field branch of the FAA Aircraft Certification Service. The project ACO has geographic responsibility for finding the design complies with applicable airworthiness standards. It administers and secures compliance with agency regulations, programs, standards, and procedures governing the design approval of replacement and modification parts. The main responsibilities of the [...]
