The NTSB's narrative final · quoted from the NTSB record

The regularly scheduled domestic passenger flight arrived at its gate and passengers began deplaning. A catering truck approached the right front service door. The catering truck driver said he applied the brakes three times in an attempt to stop the truck before it struck the airplane. The truck driver subsequently found that a “sleeve of hot/cold cups” rolled under the brake pedal and obstructed its movement.

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 CEN13LA004.
