## Discrepancy

MANUAL GEAR EXTENSION DOOR WILL NOT FULLY OPEN.  CLEANED AND LUBRICATED EXPOSED SURFACE OF THE SELECTOR VALVE.  OPS CHECKS GOOD.  NOTE THE OAT WHEN THIS HAPPED WAS 6 DEGREES FAHRENHEIT, SO COULD ALSO BE COLD RELATED SINCE THE AIRCRAFT WAS MOVED INTO A HEATED HANGAR FOR TROUBLESHOOTING.
