Plain English Summary

2/10 complexity

What this is: An Airworthiness Directive (a legally binding safety order) requiring owners and operators of specific Piper PA-46 Malibu aircraft to inspect and modify the tail section.

Who it affects: Anyone operating a Piper PA-46-310P aircraft with serial numbers 46-8408001 through 46-8408044, 46-8408046, or 46-8408048.

What it requires:

Inspection & Modification: Carry out the instructions in Piper Service Bulletin No. 783.
Timing (Part 1): Must be completed before the aircraft flies again after 5 September 1984.
Ongoing: Continue following the service bulletin requirements after the initial modification.

Why it matters: During factory testing, engineers discovered that the elevator (the moving part of the tail that controls up/down pitch) could physically jam against the fixed horizontal stabiliser. This "binding" could lock the elevator in an upward position, preventing the pilot from pushing the nose down—a potentially catastrophic loss of control situation.

Applicability: All models PA-46-310P with S/No’s 46-8408001 to 46-8408044, 46-8408046, 46-

Requirement: Piper Service Bulletin No 783.

Compliance: Part 1 prior to further flight after 5 September 1984 and thereafter as per the Requirement Document.

Background: During production flight test, interference occurred between the horizontal stabiliser bottom trailing edge and the elevator, binding the elevator in a trailing edge-up configuration, restricting down elevator travel.
