## Discrepancy

HOSE NUT WOULD TORQUE DOWN BUT LINE WAS STILL LOOSE AND LEAKED.  A LINE REMOVE FROM ANOTHER HELICOPTER WORKED FINE.  NEW LINES INSTALLED AND LINE THAT WAS INSTALLED PRIOR AND LEAKED WAS FITTED TO THE NEW TEE AND WORKED FINE.  AT TOTAL OF (3) NEW LINES WERE FITTED TO THE NEW TEE AND ALL LEAKED.  THE SAME LINES WERE ALL TRIED ON ANOTHER HELICOPTER AND LEAKED THERE ALSO.  THE TEE WITH THE LAST LINE STILL INSTALLED WAS RETURNED TO MFG FOR THE ANALYSIS.  (2) OTHER HOSES OF THE SAME PN WERE REJECTED DUE TO A COATING ON THE METAL CONNECTIONS, WOULD BREAK APART INTO FINE FLAT PIECES AND FLY AROUND AND WENT INTO THE HOSES.  (K)
