Aviation Accident Summary LAX02LA066

Groveland, CA, USA

Aircraft #1

N3624R

Piper PA-28-180

Analysis

The airplane collided with a vehicle while attempting to make a precautionary landing on a highway. When the pilot arrived in the destination area he was confronted with a low stratus cloud condition. He diverted to another airport and landed. He contacted an operator at the destination, who told him that there were visual flight operations there with cloud bases about 1,500 to 2,000 feet. He departed the diversionary airport and proceeded towards his destination. Unable to descend through or maneuver around the stratus, he returned to the original diversionary airport, which was now covered by the stratus deck, as were other local airports. Realizing he was now too low on fuel to reach an airport in visual conditions, he contacted Oakland Air Traffic Control Center and requested assistance. The center provided vectors towards airports, but due to the weather conditions, the pilot was unable to find the airports. The consensus was to land the airplane as soon as possible and before fuel exhaustion. The pilot spotted a forestry camp with a windsock near a highway. He was successful in landing on the highway; however, the highway had a curve that prevented him from seeing an on-coming vehicle. He attempted to avoid the vehicle but the wing tip clipped it, causing him to lose control and collide with trees.
