Unsafe Condition
Looseness of the stabilator torque tube bearing support fittings could result in loss of pitch control and loss of control of the airplane.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the stabilator torque tube bearing support fittings for looseness by removing the tail cone and right rear aft fuselage access door, then shaking the stabilator tip. If looseness is found, incorporate Piper Part No. 760 835 (Hi-Shear Rivet Replacement Kit) on the affected fitting before further flight. If no looseness is found, reinstall components and reinspect at intervals not exceeding 100 hours time-in-service until all four fittings have the kit installed.
