The pilot's performance of VFR flight into IMC, resulting in failure to maintain terrain clearance. Contributing to the accident was the fog.
Investigator assessment
Analysis narrative
The pilot took off from a dirt airstrip with 1/2-mile visibility to the west due to ocean fog. The pilot flew into the fog, he then turned south. However, he continued into more fog, so he turned east. When he came out of the fog, he did not have enough altitude to clear trees on top of mountainous terrain ahead. He clipped some trees with the landing gear and impacted on a hilltop, resulting in substantial damage to the airplane.
