Maintenance disclosures
DURING SCHEDULED INSPECTION IT WAS DISCOVERED THAT THE LANDING GEAR RETRACT PUSH-PULL TUBE HAD BEEN STRIKING THE FUEL LINES IN THE RT GEAR WELL. DAMAGE TO THE PUSH-PULL TUBE WAS MINIMAL AND LIMITED TO THE PAINT BEING REMOVED, DAMAGE TO THE FUEL LINES WAS SUCH THAT APPROXIMATELY 40% OF THE LINE WALL THICKNESS HAD BEEN WORN AWAY. BOTH FUEL LINES WERE REPLACED. ONE OTHER AIRCRAFT HAD BEEN FOUND WITH THIS CONDITION IN PREVIOUS YEARS, AND ALTHOUGH THAT AIRCRAFT HAD MUCH HIGHER TOTAL TIME (11,000+ HRS.) THE RT WING HAD BEEN PREVIOUSLY REMOVED AND ON THAT AIRCRAFT THE LINES WORE TO THE POINT OF LEAKING.
WHILE PERFORMING A SCHEDULED INSPECTION, 3 OF THE 4 ENGINE MOUNT (CUSHION) BOLTS WERE FOUND LOOSE. 2 REQUIRED 1 FULL TURN TO TIGHTEN, AND THE 3RD TOOK ALMOST 2 TURNS TO TIGHTEN. THE SELF LOCKING FEATURE OF THE NUTS WAS CHECKED AND APPEARED TO BE OK. IT CAN ONLY BE ASSUMED THAT THE BOLTS WERE NOT PROPERLY TORQUED BY THE MFG AT ENGINE INSTALLATION. THE BOLTS WERE TORQUED IAW SRM AND THE OPPOSITE ENGINE MOUNT BOLTS WERE CHECKED AND FOUND TO BE PROPERLY TORQUED. (K)
