Plain English Summary

2/10 complexity

Owners and operators of Robin 2160 aircraft must inspect the engine mount around the vibration-isolator bracket for weld cracks before every flight (pilot may do this and must record it in the Maintenance Release) and must permanently reinforce the mount using the manufacturer’s approved Plan 51-40-30 within 100 flight hours after 30 November 1983.

This addresses discovered cracks that could allow engine shift or separation in flight, using daily checks as an interim safety measure.
