He added that, upon touchdown, the airplane quickly veered left. He added power to correct, and "the addition of power was enough to lift the airplane slightly, but not to take off again, and so after [the airplane] floated a short distance, [it] landed again off the side of the runway." The nose landing gear collapsed in the dirt. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that, during approach to runway 16 on the private airstrip, the electronic primary flight display reported the wind from the south at 16 knots.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
