Plain English Summary

2/10 complexity

This is an Airworthiness Directive — a legally enforceable safety order issued by the aviation regulator.

What it covers: Specific Piper Malibu aeroplanes (model PA-46-310P with serial numbers 46-8408001 to 46-8608025, built roughly between 1984–1986).

The safety problem: The manufacturer discovered that collars (essentially thick washers or spacers) on bolts at the aft wing attach fitting — the hardware that bolts the rear of the wing to the fuselage — were becoming loose or missing entirely. This is a serious structural integrity issue; if the collars are missing, the wing attachment could be compromised.

What operators must do: Follow the inspection and repair instructions in Piper Service Bulletin No. 820 within 10 hours of flight time after 9 April 1986.

Why it matters: This prevents potential wing structural failure by ensuring the fasteners securing the wings to the body of the aircraft are properly retained.
