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.
