NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot reported that, during the takeoff roll, the airplane encountered a wind gust and veered left off the runway centerline. He added that the airplane became airborne but that he did not have “enough time” to avoid a parked helicopter. Subsequently, the left wing impacted the helicopter. He then reduced the engine power, and the airplane landed without further incident.
The airplane sustained substantial damage to the left wing.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The automated weather observation system about 5 nautical miles from the accident site reported that, about the time of the accident, the wind was from 230° at 12 knots, gusting to 17 knots. The pilot was departing on runway 22.


The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • The pilot’s failure to maintain directional control during the takeoff roll with gusting wind conditions.
