Plain English Summary

2/10 complexity

This AD requires operators of certain Cessna 208 Caravan aircraft to inspect and, if needed, replace the circuit breakers protecting the flap and standby flap motors so the correct 10‑amp breakers are installed. It mandates compliance with the manufacturer's service bulletin within the specified flight‑time limit because incorrectly rated breakers fitted at the factory could compromise flap function during critical takeoff and landing phases.
