## Discrepancy

SLIDE/RAFT (P/N 7A1479-13) (S/N G1863) FAILED FLAT FIRE INFLATION TEST.  UPPER INFLATION TUBE RUPTURED AT THE TOP RT CORNER.  THIS IS THE FIRST UAL SHOP VISIT FOR THIS UNIT.  DATE OF MANUFACTURE WAS 4/96 AND LAST OVERHAUL BY VENDOR WAS 5/30/96.  *S/D*  PROBABLE CAUSE FOR THE FAILURE IS PACKING DAMAGE BETWEEN TUBE MATERIAL AND THE INFLATE/DEFLATE VALVE.  SENT UNIT TO VENDOR FOR WARRANTY REPAIR.
