## Discrepancy

PILOT DID NOT RECEIVE NOSE DOWN AND LOCKED LIGHT ON APPROACH, ATTEMPTED EMERGENCY EXTENSION, NO CHANGE. FLEW BY TOWER AND VERIFIED THAT NOSE GEAR WAS NOT EXTENDED. LANDED AT MWC WITH MAIN GEAR EXTENDED AND NOSE RETRACTED. MECHANICS NOTED THAT NLG RETRACT CHAIN BETWEEN GEARBOX AND CROSSOVER WAS BROKEN CAUSING FAILURE OF GEAR TO EXTEND.
