The NTSB's narrative final · quoted from the NTSB record
An FAA inspector witnessed the accident and reported that the aircraft was landing with a right 45 degree cross wind he estimated at 14 knots with higher gusts to 17 knots. Shortly after touchdown, the aircraft ground looped and nosed over. The inspector stated that he routinely flies into and out of the airport, and, due to some trees bordering the airport, the wind conditions can sometimes be highly variable with wind shears and vortex situations. All of the pilot's flight time was accrued in tail wheel aircraft.

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 docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site 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 LAX93LA220.
