Accident Overview
While en route from Kennewick to San Diego, the pilot experienced mechanical issues and decided to perform a precautionary landing at Hart Mine, California. The aircraft subsequently crashed in a desert area and was destroyed. All three individuals on board sustained minor injuries.
Investigation Findings
Investigators determined that the accident occurred during a traffic pattern-circuit. The pilot misjudged altitude, leading to a controlled collision with the ground. Several contributing factors were identified: a suspected mechanical discrepancy, the closure of Kennewick Airport at the reported departure time, and the impossibility of the reported flight distance given the fuel on board.
Probable Cause
The official probable cause was a controlled collision with ground while in traffic pattern-circuit after the pilot misjudged altitude. Contributing factors included a suspected mechanical discrepancy, Kennewick Airport closed during reported departure time, and reported flight distance not possible with fuel on board.
