Incident Overview
A pilot reported that during landing, the nose gear began to shimmy, prompting a go-around. This same shimmy occurred on three subsequent landing attempts, each resulting in a go-around. On the fourth and final landing, the nose dropped. After exiting the airplane, the pilot discovered that the nose gear strut had broken off and was positioned toward the rear of the airplane.
Pilot Statement
The pilot stated that there were no malfunctions of the airplane during the departure takeoff, no en route stops were made, and the airplane did not collide with any obstacles. He described the landing as normal for him, noting that during a normal landing he may have touched down on all three gears at once or on the back gear.
Findings
The nose gear strut was found broken off, with the detached portion oriented rearward. The pilot did not report any mechanical issues prior to the landing attempts. No other damage or anomalies were noted.
