## Discrepancy

WHEN THE PILOT SELECTED THE LANDING GEAR HANDLE DOWN HE GOT A GEAR UNSAFE INDICATION AND COULD NOT GET IT TO CLEAR. THE ACFT LANDED WITHOUT INCIDENT. INVESTIGATION REVEALED THE NLG CAMP BOLT TUBE P/N D60-3233-82-32 WAS BENT AND THE ENDS FLARED WERE THE GUDGEONS P/N D50-3233-82-31 GO INTO THE CAMP BOLT TUBE ENDS. ALSO ONE OF THE GUDGEONS WAS MISSING CAUSING THE NLG ASSEMBLY TO TWIST AND BIND. THIS IS THE SECOND INCIDENT WITH A DA42 NLG INVOLVING THE CAMP BOLT TUBE AND GUDGEON SEE SDR #2009FA0000234 DATED 3/17/09. IT LOOKS LIKE THE NLG ACTUATOR IS PUTTING TO MUCH FORCE ON THE CAMP BOLT TUBE WHEN THE NLG IS IN THE EXTENDED POSITION.
