Superseded. A later AD replaced this one: AD 96-18-02. Comply with the one in force.
The following airplane models and serial numbers, certificated in any category, that are equipped with metal spar wings: --Model 8KCAB airplanes, serial numbers 643-90 through 762-95; --Model 8KCAB airplanes, all serial numbers, that are equipped with metal spar wings, wing assembly part number 7-1521 (installed in accordance with American Champion Service Kit 403); --Model 8GCBC airplanes, serial numbers 361-91 through 374-95; --Model 8GCBC airplanes, all serial numbers, that are equipped with metal spar wings, wing assembly part number 7-1542; --Model 7GCBC airplanes, serial numbers 1200-94 through 1212-95; --Model 7GCBC airplanes, all serial numbers, that are equipped with metal spar wings, wing assembly part number 7-1541; --Model 7ECA airplanes, serial numbers 1355-95 through 1357-95; and --Model 7ECA airplanes, all serial numbers, that are equipped with metal spar wings, wing assembly part number 7-1567.
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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
