## Discrepancy

PRESSURE LINE FROM NR 1 ENGINE DRIVEN PUMP CHAFED AT AFTMOST CLAMP LOCATION (NEAR NR 1 SYSTEM RESERVOIR) UNTIL THE LINE FAILED UNDER PRESSURE CAUSING A COMPLETE LOSS OF NR 1 HYDRAULIC SYSTEM IN FLIGHT.  CLAMP CUSHION FAILED CAUSING METAL TO METAL CONTACT.  SUSPECT THAT DEFECT WAS NOT READILY VISIBLE BEFORE FAILURE.  (K)
