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

During the demonstration flight, the pilot-in-command (PIC)/airplane owner occupied the right front seat, and the prospective buyer occupied the left front seat. After circling the airport to confirm wind sock position and that the 2,400-foot grass runway was clear of obstructions, a pattern entry was made for landing to the south. On final approach, the pilots noted that the airplane was low on the approach, and the left seat pilot added power. Subsequently, the airplane was too far down the runway and the airspeed was too fast for the landing. The PIC called for a go-around, and the left seat pilot added full power. The airplane flew in ground effect, about 5 feet agl, for several hundred feet. Subsequently, the airplane climbed to about 20 feet agl, and the left seat pilot retracted the landing gear. The PIC raised the flaps, and the airplane settled to 5 to 10 feet agl and impacted a fence and trees. During a post accident compression check of the engine, the prospective buyer and his mechanic found that the #2 intake valve was leaking.

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

The pilot's premature raising of the flaps.
