BOTH OCCUPANTS OF THE LOW WING AIRPLANE STATED THAT THEY DID NOT SEE OR HEAR RADIO CALLS FROM THE HIGH WING AIRPLANE. THE ON SCENE INVESTIGATION FOUND THAT BOTH AIRPLANES WERE WHITE IN OVERALL COLOR WITH DARK TRIM. THE TERRAIN THEY WERE OPERATING OVER WAS SOW COVERED.

Everything on this page comes from the NTSB's public records. The narrative, probable cause and findings are the NTSB's own words; the coded tables behind the report are written out in plain English, with pilots' ages, home towns and medical details left out. The documents and photographs are the NTSB's docket, shown as the NTSB released them. This site's own text never names anyone involved. A preliminary report can change; the final report usually follows one to two years later, and the page is refreshed when it does.
