Plain English Summary

2/10 complexity

What this does: This directive orders owners and operators of specific Piper PA-46 Malibu aircraft to check the fuselage (the main body of the plane) and install any missing rivets.

Who it affects: Owners of Piper PA-46-310P and PA-46-350P aircraft with specific serial numbers built between 1984 and 1986. The serial numbers are listed precisely in the document.

Why it matters: During manufacturing, some rivets required for the pressure cabin's fatigue certification were accidentally left out. Missing rivets could weaken the structure that keeps the cabin pressurized at high altitude, potentially leading to structural failure over time.

What must be done:

Inspect the fuselage and install missing rivets following Piper Service Bulletin No. 959
Complete this by the next scheduled maintenance check (within 110 flight hours) after 22 July 1993
If already done, no further action needed
