Plain English Summary

2/10 complexity

This is a mandatory aircraft safety order (called an Airworthiness Directive) for owners and operators of Partenavia P68 aircraft.

What it requires: You must inspect a specific control rod — the rudder trim tab control rod (part number 68-506053) — to ensure it's installed correctly according to the manufacturer's Service Bulletin No. 32/10/77.

If you find a problem: If the rod isn't installed correctly, you must remove it immediately and check it for:

Physical bending or distortion (visual check)
Cracks (using a magnetic particle inspection technique)

When to do it:

Immediately: Before the aircraft flies again, if not already done
Ongoing: Repeat this inspection every 100 hours of flight time

Why it matters: This prevents potential failure of the rudder trim system, which could lead to loss of directional control of the aircraft.
