Narrative:

Nose gear failed to extend fully and lock down. [We] circled the airfield for approximately one hour and 30 minutes while completing abnormal and emergency checklist. [We] exhausted all options. I completed the emergency checklist for landing with nose gear up. The engine was shut down and feathered on landing at which time 2 prop blades contacted the runway as the nose came down. Blades were abraded and bent slightly. Aircraft structure was not damaged beyond the 2 prop blades. No passengers were on board. Engine was not running and prop was slowly turning when contact with runway occurred. As of this time the cause of the nose gear failure has not been determined. Pending further investigation I shall not be able to offer my opinion on cause of malfunction. In my opinion all proper procedures were followed with regards to afm procedure and emergency checklist. I owe a great thanks to the technicians and ground maintenance personnel as they were a valuable asset in assisting me with this problem; very good CRM.
