## Discrepancy

NLG LANDING GEAR RETRACTION: ON APPROACH, AFTER GEAR HAD BEEN EXTENDED FOR A WHILE AND FLAPS HAD BEEN SELECTED TO FULL, WE GOT THE AMBER WOW MISCOMPARE CAS. WE INITIATED A MISSED APPROACH, DURING WHICH WE BROUGHT THE GEAR HANDLE UP, BUT GEAR WOULD NOT RETRACT. WE DIVERTED TO A LONGER RUNWAY; GEAR EXTENSION AND LANDING WERE NORMAL. AT SOME POINT DURING TAXI THE WOW MISCOMPARE CAS EXTINGUISHED. // SIGNOFF// REMOVED NLG WIRE HARNESS AND INSTALLED A NEW CUSTOMER SUPPLIED NLG WIRE IAW CE680A AMM 32-20-00. PERFORMED OPERATIONAL CHECK OF MLG EXTENSION AND RETRACTION IN REFERENCE TO CE-680A AMM 32-30-00. OPS CHECK GOOD AT THIS TIME. PN ON: 8469800-2 PN OFF: 8469800-1
