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

The pilot reported that he left the windows open while completing the Start-up checklist and while taxiing to the runway. During the takeoff roll, he noticed that the passenger window was unsecured. While attempting to secure the window, he momentarily took his eyes off the runway. As he looked back at the runway, the airplane was traveling to the left side of the runway. With insufficient runway to correct direction, the airplane impacted a runway distance marker sign. The airplane sustained substantial damage to the right horizontal stabilizer and elevator. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

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 GAA19CA472.
