Plain English Summary

2/10 complexity

What this does: This is a mandatory safety notice (called an Airworthiness Directive) for owners and operators of Piper PA-46 (Malibu) aircraft.

What you must do: Inspect and repair the screws that hold the aileron balance weights (small weights on the wing control surfaces that prevent dangerous vibrations). You must follow the specific instructions in Piper Service Bulletin No. 921, dated 15 August 1989.

Deadline: Complete this work by the next time you renew your aircraft's Maintenance Release (a document certifying the plane is airworthy) after 25 January 1990.

Why it matters: Cracks can develop around the screw holes holding these balance weights. If left unchecked, the weights could fall off, causing the ailerons (wing flaps that control rolling) to flutter or fail, which could lead to loss of control of the aircraft.
