Plain English Summary

4/10 complexity

This Airworthiness Directive requires owners/operators of all Beechcraft 76 (Duchess) aircraft to inspect the internal flap hinge bracket attachment ribs for hidden corrosion, using leading-edge skin removal or inspection panels approved by the regulator or a CAR 35 authorised person. The inspection must occur within 25 flight-hours or 3 months and then at intervals not exceeding 3 years. The stated purpose is to detect advanced internal corrosion that can exist without external signs; compliance creates inspection, repair costs and aircraft downtime.
