## Discrepancy

LANDING GEAR DID NOT RETRACT FULLY UPON GEAR RETRACTION. THE NOSE RED UNLOCK LIGHT REMAINED ON.  WE COULD HEAR THAT THE GEAR DOORS WERE STILL OPEN.  THE NOSE GEAR CYCLED 3 TIMES.  THEN CLIMBING THROUGH 4000 FT THE GEAR RETRACTED FULLY AND THE NOSE RED UNLOCK LIGHT WENT OUT. THE LANDING GEAR EXTENDED NORMALLY PRIOR TO LANDING.  ACCOMPLISHED GEAR BUMP TROUBLESHOOTING CHECKLIST IAW MM 32-20-00.  FOUND ALL UPLOCK SWITCHES OUT OF SPECIFACTIONS, ADJUSTED UPLOCK SWITCHES IAW MM CHAPTER 32-30-05.  GEAR SWING OPS CHECK GOOD.
