The NTSB's narrative final · quoted from the NTSB record
The airplane stalled and collided with terrain in the takeoff initial climb. A witness reported that after liftoff the airplane climbed out of ground effect and stalled. The airplane returned back into ground effect, and the pilot lowered the nose to regain speed. He rotated out of ground effect, and subsequently stalled. The airplane returned to ground effect and, again, the pilot attempted to regain speed. As the airplane was approaching a cliff, it lifted out of ground effect and banked to the right. The left wing appeared to stall and the airplane impacted terrain in a nose and left wing low attitude. Based upon the atmospheric conditions provided by the METAR, the density altitude was calculated to be 4,896 feet. A Federal Aviation Administration maintenance inspector examined the airplane after the accident. He reported that he ran the engine, and found no anomalies or malfunctions that would have resulted in a decrease in power.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number LAX04LA191.
