Aircraft damage: Substantial
Category:Accident
Location:Oceano Dunes SVRA, San Luis Obispo County, Oceano, CA -   United States of America
Phase: Manoeuvring (airshow, firefighting, ag.ops.)
Nature:Private
Departure airport:Oceano, CA (L52)
Destination airport:Oceano, CA (L52)
Investigating agency: NTSB
Narrative:
Witnesses reported that they observed the airplane flying low above the beach before it ascended abruptly. When the airplane was about 150 to 200 feet above the ground, the ascent stopped, and the airplane then descended in a nose low attitude to ground impact. Witnesses also reported that the engine sounded normal during the accident sequence. Postaccident examination of the airframe and engine revealed no preimpact mechanical malfunctions or failures that would have precluded normal operation.
The pilot had a reported history of marijuana abuse. Toxicology testing on the pilot was positive for tetrahydrocannabinol at levels that indicate he was likely impaired during the flight. This impairment likely affected the pilotís ability to maintain airplane control and his decision to begin a low-level flight maneuver at an altitude that was not sufficient for recovery before impact with the ground.


Probable Cause: The pilotís failure to maintain airplane control and his improper decision to begin a low-level maneuver at an altitude that was not sufficient for recovery before ground impact. Contributing to the accident was the pilotís impairment from marijuana use.
