Airworthiness Directives; American Champion Aircraft Corporation Models 8KCAB, 8GCBC, 7GCBC, and 7ECA Airplanes

Короткий зміст

This amendment adopts a new airworthiness directive (AD) that applies to American Champion Aircraft Corporation (American Champion) Models 8KCAB, 8GCBC, 7GCBC, and 7ECA airplanes that are equipped with metal spar wings. This action requires inspecting (one time) the wing front strut fittings for cracks or scratches, replacing any wing front strut fittings found cracked or scratched, and reporting the inspection results to the Federal Aviation Administration (FAA). Fatigue cracks found on the wing front strut fittings on two Model 8KCAB airplanes prompted this action. The actions specified by this AD are intended to prevent structural failure of a wing assembly caused by cracked or scratched wing front strut fittings, which, if not detected and corrected, could result in loss of control of the airplane.
