## Discrepancy

WELL, ON APPROACH INTO DAL WHEN WE CALLED FOR “GEAR DOWN“ THE GEAR WAS SELECTED DOWN AND ONLY THE LEFT MAIN GEAR CAME DOWN AND LOCKED.

PULL THE MANUAL HANDLE AND BLUE THE BOTTLE WITH A SUCCESSFUL RELEASE AND GEAR DOWN LOCKED. GOT VECTORED FOR ANOTHER LANDING AND LANDED IN DAL WITHOUT ISSUES. GAINED ACCESS TO UPLOCK SWITCHES AND FOUND THAT THE NOSE UPLOCK SWITCH WAS NOT FULLY DEPRESSED. INSTALLED NEW UPLOCK SWITCH, CYCLED SYSTEM 10 TIMES WITH NO DEFECTS NOTED.
