AD/P68/15 - Fin, Rudder Upper Hinge Attachment Area - Modification

This is an Airworthiness Directive — a mandatory safety order issued by the Civil Aviation Safety Authority (CASA) that has the force of law.

What it does: Requires owners of specific Italian-made Partenavia aircraft to modify the hinge that attaches the rudder (the movable part of the tail) to the fin (the fixed vertical part of the tail).

Who is affected: Owners and operators of Partenavia P68 and P68B model aeroplanes with serial numbers prior to 129.

What must be done: Carry out a structural modification to the fin/rudder upper hinge attachment area exactly as described in the manufacturer's Service Bulletin No. 34, Revision 1 (a technical instruction manual from the aircraft maker).

Deadline: Within 100 hours of flight time after 31 March 1979.

Why it matters: To prevent potential failure of the rudder attachment, which could lead to loss of directional control of the aircraft.
