Restore solid attachment of the doors to the fuselage
Due to normal wear and lack of lube, the door hinge clevis pins should be replaced from time to time to maintain the proper operation of the doors. The set includes 2 clevis pins, 6 washers, and 2 cotter keys. All the hardware is FAA approved for all Piper aircraft.
