The NTSB's narrative for the Swearingen SA226-TC final · quoted from the NTSB record
The accident involved 2 Swearingen airplanes. The pilot of the first airplane reported that he had taxied north for departure. There were several company aircraft in front of him in line for departure so he came to a complete stop. The pilot of the second airplane reported that he was also taxiing north for departure. He had seen the lights from an aircraft holding short of runway 17R; however, he did not see the lights of the first airplane until it was too late. The pilot of the second airplane reported he applied full brakes and used reverse thrust but was unable to avoid hitting the first airplane. Both airplanes were substantially damaged.

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 DEN04FA027.
