Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that when the airplane lifted off he became distracted by his headset's noise canceling control and suddenly the nose wheel of the airplane hit the ground hard. The pilot immediately pulled back on the controls and initiated a climb to assess the damage. After 15 minutes of flight, the emergency crew on the ground assessed that the nose gear was bent and the pilot prepared for an emergency landing. The pilot opted to land on the grass and as he set the airplane down on the surface the front gear leg collapsed and the airplane tilted up on its propeller before falling back down onto its main gear and substantially damaging the rudder. The pilot reported no pre-impact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation.

Factual narrative

The pilot reported that when the airplane lifted off he became distracted by his headsets noise canceling control and suddenly the nose wheel of the airplane hit the ground hard. The pilot immediately pulled back on the controls and took the airplane up to assess the damage. After 15 minutes of flight the emergency crew on the ground assessed that the nose gear was bent and the pilot prepared for an emergency landing. The pilot opted to land on the grass and as he set the airplane down on the surface the front gear leg gave away and the airplane tilted up on its propeller before falling back down onto its main gear and substantially damaging the rudder. The pilot reported no pre-impact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation.
