What was found
DURING LANDING GEAR RETRACTION TEST, NOSE GEAR WOULD NOT FULLY RETRACT. THE BELLCRANK WAS FOUND OVERCENTER, CAUSING THE ROLLER TO MISS THE UPLOCK HOOK AND RESTRICT THE NOSE GEAR TRAVEL. THE SPRING WAS FOUND STRETCHED AND NOT PROVIDING ADEQUATE TENSION. THE SPRING WAS REPLACED AND OPERATION WAS NORMAL. THIS DEFECT CAUSED THE NOSE GEAR TO STAY PARTIALLY OUT OF THE WHEEL WELL AND THE GEAR DOORS TO REMAIN APPROXIMATELY 30 DEGREES OPEN. THIS COULD RESULT IN FAILURE OF THE DOORS AND POSSIBLE JAMMING OF THE NOSE GEAR.
