What to do

Operators and maintenance teams should review repair histories for the specified King Air models to identify any wing lower surface skin repairs near the fuselage keel and wing main spar intersection. A one-time visual inspection of the repair and surrounding structure should be conducted by the next scheduled wing center section inspection, including internal detailed inspections of spar doublers and fasteners. If damage is found, contact Hawker Beechcraft Corporation for repair instructions.
