The NTSB's narrative for the Cessna C172 final · quoted from the NTSB record
The Cessna was stationary in the run-up area for runway 11L, facing an approximate heading of 240 degrees. They had just completed an engine run-up and the student was conducting an instrument scan. The flight instructor looked up momentarily to see the Maule headed straight for the nose of the Cessna. The airline transport pilot aboard the Maule stated that despite the S-turns, he did not see the Cessna prior to the impact. The right wing of the Maule went under the left wing of the Cessna, the propeller blade of the Maule penetrated the windscreen on the left side of the Cessna and the propellers of both airplanes struck each other substantially damaging both airplanes.
The complete narrative as the NTSB published it. The NTSB's docket holds the report as a PDF and any photographs, statements and other documents from the investigation.

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 DEN04LA053.
