## Discrepancy

THE LEFT NACELLE OUTBOARD STRINGER NR 1 WAS DAMAGED BY THE FORWARD GEAR DOOR TENSIONER WHICH HAD DISCONNECTED BECAUSE THE RETAINING BOLT FELL OUT.  THE LT STRINGER NR 1 HAD BEEN PREVIOUSLY REPAIRED BY INSERTION FOR THE SAME REASON.  SINCE THE INSERTION REPAIR WAS THE ONLY STRUCTURE DAMAGED, IT WAS REPLACED PER THE ORIGINAL REPAIR REPORT, AERODESIGN REPORT NR 1139-1, REV IR, DATED 5-20-94.
