## Discrepancy

DURING LAST 6 AIRCRAFT RECOVERED BY FACILITY, 5 OF THESE AIRCRAFT HAD TO HAVE THE TOP LONGERON REPLACED BECAUSE OF CORROSION DUE TO WATER BEING TRAPPED UNDER THE SLIDING WINDOW CHANNEL ON THE LEFT SIDE.  IN ALL CASES, THE SLIDING CHANNELS IN LONGERON AREA WERE SEVERELY CORRODED BEYOND JUST CLEANING AND HAD TO BE REPAIRED.
