WARNING: Airworthiness Directive applicability may depend on your specific aircraft configuration,
including installed engines, propellers, and appliances. Results shown here may be incomplete if your full
configuration is not specified. Always consult official FAA sources and your A&P mechanic or IA for
definitive compliance determinations.
Parser coverage is imperfect. "Possible" results require manual verification of the applicability section.
Evaluated 7 candidate ADs: 7 confirmed, 0 possible, 0 excluded.
Engine model not supplied — engine-constrained ADs surface as "possible". Propeller model not supplied — prop-constrained ADs surface as "possible".
