Plain English Summary

2/10 complexity

This directive orders owners/operators of certain Piper PA‑46 Malibu airplanes to correct a flap drive defect that can cause one wing’s flaps to bind, producing asymmetric flaps and a severe loss-of-control hazard. Compliance follows Piper Service Bulletin 780A under phased deadlines, and the update now requires installing a redesigned, lower‑pressure flap selector valve as an added safeguard.

Amdt 1

Flap Drive Mechanism 1/86

Applicability: All model PA-46 and PA-46-310P with S/No’s referenced in the Requirement Document.

Requirement: Piper Service Bulletin 780A.

Compliance: Part 1 of Requirement Document: Within 25 hours time in service after 31 October 1984.

Part 2 of Requirement Document: At the next scheduled inspection for maintenance release issue after 31 January 1986.

Background: Field reports of flap system malfunction indicate that the flap roller has bound in the inboard track. Such binding could cause an asymmetric (split flap) condition which could result in difficulty maintaining lateral control. This amendment references Revision A of the Requirement Document which extends the requirement to include a new flap selector valve with a lower relief valve setting.
