NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

About 100 feet above ground level during initial climb, the experimental airplane's engine began vibrating, sputtering, and losing power. The pilot adjusted the mixture and throttle controls, but was unable to regain sufficient rpm to sustain flight. The pilot made a forced landing on rough desert terrain, about 1 mile from the departure airport. During the subsequent engine examination, no evidence of case or cylinder damage was noted. Oil was found on the dipstick, the carburetor was intact, and the throttle control was secure. The reason for the partial loss of engine power was not determined.

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

A partial loss of engine power for undetermined nonmechanical reasons. A contributing factor was the rough nature of the terrain used for the forced landing.
