NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airplane impacted the terrain during an aborted takeoff. The pilot reported the purpose of the flight was to check the propeller pitch because he had adjusted it. He reported that airplane was "sluggish" during the initial takeoff climb so he leveled off. He reported he checked the engine temperature and rpm, and the engine was close to "over revving." The pilot reported that because he had difficulty maintaining altitude, he decided to abort the takeoff by turning left into the wind so he could land on the grass alongside the runway. The pilot reported the airplane contacted the grass "…with a strong side load on the landing gear." Post accident inspection of the airplane revealed the propeller had been adjusted to too high of a pitch setting.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot failed to maintain aircraft control during the forced landing. A factor associated with the accident was the excessive adjustment that the pilot made to the propeller's pitch prior to the flight.
