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 [...]

Fatigue critical structure means airplane structure that is susceptible to fatigue cracking that could contribute to a catastrophic failure, as determined in accordance with 14 CFR §25.571. Fatigue critical structure includes structure, which, if repaired or altered, could be susceptible to fatigue cracking and contribute to a catastrophic failure. Such structure may be part of [...]
