## Discrepancy

PERFORMED AN AIR TURN BACK TO TPA DUE TO A NOSE LANDING GEAR UNSAFE INDICATION AND NOSE EAR DID NOT RETRACT.  AN EMERGENCY WAS DECLARED.   TPA MAINTENANCE FOUND THE NLG SCHRADER VALVE LOOSE.  THE VALVE WAS SECURED AND THE STRUT WAS SERVICED.  A LOG WAS CREATED TO RE-CHECK THE SERVICING.
