## Discrepancy

WHILE TROUBLESHOOTING AN AIR LEAK ON THE RT DOOR, DISCOVERED THE FWD DOOR LATCH WAS NOT OPERATING DUE TO A BROKEN LOWER LATCH GUIDE.  FURTHER INVESTIGATION REVEALED THE BROKEN LATCH GUIDE WAS A P/N TB1025042100 GUIDE MADE OF PLASTIC INSTEAD OF THE PROPER P/N TB1025042102 GUIDE MADE OF MACHINED ALUMINUM.  A CHECK OF THE OTHER DOOR LATCHES ON THE RT AND LT DOORS ALSO FOUND IMPROPER P/N GUIDES INSTALLED.  THERE WAS NO RECORD OR INDICATIONS THAT THE GUIDES HAD BEEN PREVIOUSLY REPLACED.  RECOMMEND INSPECTION OF DOOR LATCHES AND REPLACEMENT OF IMPROPER PARTS.
