Piper PA 34-200T Crashes into Trees After Engine Power Loss

Casualties unknown • San Andreas, CA, US

A private pilot flying a twin-engine aircraft collided with trees in hilly terrain following an engine failure during takeoff in foggy conditions.

What happened

After taking off in foggy conditions, a Piper PA 34-200T collided with trees located in hilly terrain approximately 8 miles southwest of the airport. The pilot, who was a private pilot without multi-engine or instrument ratings, reported that the aircraft experienced a loss of power in the left engine during the flight. Following the power loss, the pilot did not execute the required emergency procedures for an engine failure.

The investigation

An examination of the engine was conducted and revealed no mechanical failures or malfunctions. Further investigation into the pilot's credentials and records held by the FAA in Oklahoma City, Oklahoma, uncovered several regulatory discrepancies. At the time of the accident, the pilot's medical certificate had expired, and he lacked an airplane multi-engine class rating as well as an instrument airplane rating. Additionally, there was no proof of a current biennial flight review. A review of the pilot's airmen records also showed three previous suspensions of his private pilot certificate due to violations of Federal Aviation Regulations.

Probable cause

The pilot failed to perform the proper emergency procedures following a loss of power in the left engine while operating in foggy conditions without the proper multi-engine or instrument ratings.
