## Discrepancy

NOSE FORK SEPARATED FROM NLG AT AN UNKNOWN TIME DURING FLIGHT. AIRCRAFT WAS IN A TRAINING ENVIRONMENT WITH REPETITIVE LANDINGS. REGULAR INSPECTION AND LUBRICATION OF THE FORK AND GEAR AT 100 HOUR INSPECTIONS. SUSPECT FAILURE OF THREADED ROD DUE TO NO PRIOR NOSE WHEEL SHIMMY REPORTED. SUSPECT ROD WAS STRETCHED THROUGH REPETITIVE INSPECTIONS AND POSSIBLE HARD LANDINGS. RECOMMEND ADDING DIMENSIONAL INSPECTION TO SIL20C1-014.
