## Discrepancy

(CAN) AT THE END OF THE LANDING ROLL IT WAS NOTICED THAT NR 2 HYDRAULIC QUANTITY GAUGE WAS AT ZERO.  THEN WHEN TAXIING ONTO RAMP, THE NR 1 HYDRAULIC PUMP FAILED.  INVESTIGATION FOUND A HYDRAULIC LINE BADLY CHAFED WITH A SMALL HOLE ALLOWING NR 2 SYSTEM TO DRAIN MOST FLUID.  IT IS BELIEVED THAT GEAR SELECTION AND LOWERING CAUSED THE CHAFED LINE TO FINALLY BURST.
