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 [...]

Designated Engineering Representatives – A FAA designee, a DER may approve engineering technical data within the limits of his/her authority by means of FAA Form 8110-3 and, when authorized by the ACO, may witness FAA compliance tests and perform compliance inspections. DER’s will follow the procedures of FAA Order 8110.4, Type Certification Process. The specific [...]

Monocoque fuselage design relies on the strength of the skin (also known as the shell or covering) to carry the various loads. True monocoque construction does not use formers, frame assemblies, or bulkheads to give shape to the fuselage.

Semimonocoque Fuselage Design: Semimonocoque fuselage design may use any combination of longerons, stringers,bulkheads, and frames to reinforce the skin and maintain the cross-sectional shape of the fuselage. The skin, which is fastened to all of these members, helps resist shear load and, together with the longitudinal members, the tension and bending loads. Longerons resist the [...]
