## Discrepancy

ON TAKEOFF THE NOSE GEAR CAME UP WITH A LOUD BANG.  IT WAS BOTH AUDIBLE AND FELT THROUGH THE COCKPIT FLOOR.  IT SEEMED TO RETRACT SLIGHTLY SLOWER THAN NORMAL.  ALL THE LIGHTS WERE OUT.  IT EXTENDED NORMALLY. I¿M N POSTFLIGHT I NOTICED ONE OF THE HYDRAULIC LINES APPEARS TO BE FRAYED.  IT WAS NOT THAT WAY WHEN WE TOOK OFF IN PHX.   ADJUSTED NLG UPLOCK SWITCH. OPS CHECK GOOD. IAW AMM 32-60-00
