Plain English Summary

3/10 complexity

This mandatory Airworthiness Directive requires owners/operators of certain Piper PA-46-310P aircraft (specific serial numbers) to fix a design defect that can cause complete engine failure. It orders immediate inspection of the turbocharger oil scavenge reservoir (with repeat checks until replaced by the improved part) and modification of the lower engine cowling to prevent the reservoir from detaching and causing total engine loss.
