Plain English Summary

2/10 complexity

This AD applies to specified Beechcraft 77 (Skipper) serial numbers and makes Beechcraft Service Instruction No. 1088 mandatory to inspect and, if needed, rectify wing attach bolts and internal nutplates because of possible thread damage.

Compliance is required before the next flight, so owners/operators bear inspection/repair costs and may face immediate grounding and maintenance scheduling to restore airworthiness.
