## Discrepancy

GEAR WOULD NOT UNLOAD IN UP POSITION WHEN RETRACTED IN SHOP.  FOUND RIGHT GEAR DOOR OUTBOARD END HAD LOOSE LOCKNUT.  SUSPECT MECHANIC ADJUSTED DOOR AND DID NOT TIGHTEN NUT.  IF DOOR WAS LATER DISCONNECTED, THE CONTROL ARM COULD HAVE BEEN MOVED INADVERTENTLY WHICH COULD KEEP THE GEAR FROM RETRACTING FULLY.  READJUSTED CONTROL ARM AND TIGHTENED NUTS.  OPS CHECK SATISFACTORY.
