Piper PA-18 crashes in irrigation ditch after gust of wind (N3765Z)

Sonoma Valley, CA, US

On March 13, 1990, a Piper PA-18 (registration N3765Z) operated by Best, William was involved in an aviation accident near Sonoma Valley, CA. Investigators recorded the probable cause as: The pilot's loss of control during takeoff due to a gust of wind from the rear, compounded by insufficient altitude to recover. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A Piper PA-18 experienced a rear gust shortly after takeoff, causing the pilot to lose control with insufficient altitude to recover, resulting in a crash into an irrigation ditch.

What happened

The incident occurred during the initial climb phase following takeoff. Shortly after liftoff, the aircraft encountered a gust of wind originating from the rear. This sudden aerodynamic disturbance caused the pilot to lose control of the Piper PA-18.

Due to the low altitude at which the loss of control occurred, there was insufficient vertical distance remaining for the pilot to recover the aircraft's attitude and regain stable flight. The pilot attempted an emergency landing off the right side of the runway, resulting in the aircraft impacting an irrigation ditch.

The investigation

Post-accident examination revealed no evidence of pre-existing mechanical issues. The pilot reported that there were no malfunctions with the aircraft prior to the accident. The structural damage was consistent with a high-energy impact into the ground at a low altitude, leaving no room for recovery maneuvers.

Probable cause

The pilot's loss of control during takeoff due to a gust of wind from the rear, compounded by insufficient altitude to recover.
