What was found
(CAN) TORQUE TRANSDUCER AND OIL SUPPLY LINES MEET. DETERMINED THAT LINE 577.11.12.105B AT TQ LIMITER CONNECTION WAS LOOSE. IT SURMISED THAT BY MULTIPLE CONNECT/RE-CONNECT AT 'T', BENDING AND POTENTIAL FOR MOVEMENT OF ENTIRE PLUMBING BUNDLE, LACK OF TORQUE APPLIED AT TQ LIMITER NUT CONNECTION, CAUSED BREACH AND RESULTED IN LEAK. TIGHTENING OF NUT AND SUBSEQUENT GROUND RUNS AND TEST FLIGHT SHOWED NO FURTHER SIGNS OF OIL LEAKAGE. MORE THOROUGH POST INSP ENGINE GROUND RUN WILL BE INCORPORATED. SUGGESTION : BENDING POTENTIAL IS GREAT, CONSIDERING LINES ARE OF COMBINED RIGID AND FLEXIBLE DESIGN. IT WOULD BE ADVANTAGEOUS TO INCORPORATE TEE FIT ING AND SAFTIED CAP FOR PURPOSE OF ATTACHMENT.
