## Discrepancy

(CAN) GEARBOX LOW OIL PRESSURE LIGHT CAME ON, ENGINE SHUTDOWN AND AIRCRAFT LANDED. GEARBOX OIL LEVEL FOUND LOW BUT STILL ON DIP STICK. OIL LEAK TRACED TO FAILED FITTING ON SUPERCHARGER. UNIT HAS OVERHAUL LIFE OF 2,500 HOURS. LINE IS PRESSURE CHECKED (LOW PRESSURE) AT OVERHAUL. CRACK INITIATED FROM UNDER (B) NUT AND WOULD NOT HAVE BEEN VISIBLE AT OVERHAUL. OF 4 EXTERNAL LINES ON UNIT ONLY LINE FROM GEARBOX IS REPLACED AT OVERHAUL. THESE LINES ARE SUBJECT TO HANDLING STRESS. WE ARE LOOKING AT HAVING ALL LINES REPLACED AT EACH OVERHAUL.  NOTE: SUPERCHARGER P/N 139312, USES AN OIL LINE WITH BANJO FITTINGS AND CAN THEREFORE BE INSPECTED TO GREATER DEGREE AT OVERHUAL.
