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

The 18,730-hour airline transport rated pilot lost control of the homebuilt airplane while executing a GPS instrument approach to Runway 14 at a non-towered airport. The airport has two instrument approaches to Runway 14; a VOR/DME and a GPS. The published weather minimums for the GPS approach to Runway 14 was 500-foot ceiling and one mile visibility. One witness stated that the pilot made "two passes" before crashing at the runway's east end, and also stated that heavy fog prevailed at the time of the accident. Another witness said that they heard two "loud pops," came outside and saw smoke and a small fire, but no airplane. This witness also confirmed that it was foggy at the time. A post-impact fire consumed most of the airframe. A detailed examination of the airplane failed to reveal any anomalies with the airframe, structure, or systems. The engine was examined, and no mechanical anomalies were found. The examination of the propeller revealed one blade was slightly bent "forward"; the other blade did not have the appearance of being bent. Both blades had leading edge polishing. The propeller signatures are consistent with a propeller absorbing rotational energy with power into soft soil or sand. The flap actuator was found in the extended position, corresponding to a flaps "up" position. The automated weather station, located approximately 17-miles south of the accident site, reported at 0851; a 5-mile visibility in mist, a scattered sky at 10,000 feet and winds from 140 degrees at 6 knots.

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

The pilot's loss of control while performing an instrument approach. A contributing factor was the prevailing fog.
