Narrative:
Destroyed after colliding with a ridge line near Danville, California. The pilot received fatal injuries. No flight plan was filed for the personal cross country flight. Instrument meteorological conditions were reported at the accident site. The flight had originated at Oakland, California, about 10:32 hours PDT, on the morning of the accident. The pilot was receiving VFR traffic advisories from Bay Tracon while on his own navigation. Family members were expecting the aircraft's arrival at Placerville, California.

The pilot had contacted Oakland ground control and stated that he was VFR to Placerville with a planned cruise altitude of 2,500 feet amsl. When the weather conditions improved, the pilot was cleared to runway 27R and was requested to squawk code 4564 on the transponder.

The pilot was subsequently cleared for takeoff on runway 27R and a right turnout was approved. The local controller advised when radar contact was established and requested the aircraft's altitude. The pilot responded that he was at 1,000 feet.

The pilot was requested to contact departure control on frequency 135.4 MHz. The pilot established contact with departure and advised that he was level at 1,500 feet. Departure control acknowledged and advised the pilot to climb VFR at his discretion and to resume his own navigation.

Subsequently, the pilot was advised of traffic at 10 o'clock, 1 mile eastbound at 3,500 feet. There was no response to two calls. The controller transmitted a call to the aircraft stating that "radar contact lost 5 miles south of Mount Diablo." The controller requested another aircraft in the area to attempt contact with the accident pilot. There was no response.

Radar contact was lost about 9 nautical miles northeast of Oakland at 2,100 feet amsl in the vicinity of a 2,245-foot-high ridge line. The wreckage was located in the Las Trampas Regional Wilderness Park. According to park rangers, they smelled and observed black smoke towards the top of the fog-shrouded ridge line.

At 11:05 hours PDT, a sheriff's officer was responding to the brush fire call. He noted that there were patches of fog along the top of Rocky Ridge. The brush fire was located about 100 yards south of the Rocky Ridge repeater antenna site. The antenna rises 220 feet above the ground/terrain level.

According to FAA inspectors on scene, the airplane had collided with Rocky Ridge. They estimated the accident site elevation to be 1,980 feet amsl, and the first impact point to be about 20 to 30 feet below the ridge. A post-crash fire consumed a major portion of the airplane structure and control continuity could not be established.

The propeller was located about 1/4-mile beyond the wreckage. The propeller attach studs were found still in the engine crankshaft flange. The propeller exhibited torsional twisting, aft bending, and chord-wise striations.
