Plain English Summary

2/10 complexity

This airworthiness directive mandates owners and operators of certain Twin Commander piston aircraft (specific 680/681/685/690/695 models and serial numbers) to inspect the main cabin door locking bayonet pins because they may not fully engage the retaining blocks, risking an in‑flight door opening.

Inspections must follow Rockwell International Service Bulletin No. 176 and be completed within 25 flight hours after 17 October 1980.
