The NTSB's narrative for the Gulfstream-Schweizer A/C CORP GULFSTREAM AM G-164B final · quoted from the NTSB record
The two airplanes were conducting agricultural operations at a private airstrip. The pilot of the landing airplane reported that, while airborne, he noticed the departing airplane was being loaded at the tender truck. The pilot of the landing airplane estimated that he would have enough time to land and clear the runway before the departing airplane was finished loading. The pilot of the departing airplane reported that after loading, he positioned his airplane on the runway and began his takeoff roll. Meanwhile, the pilot of the landing airplane touched down in the opposite direction of the departing airplane. The pilot of the landing airplane reported that while he was slowing down on the landing roll, he looked over his airplane’s hopper and noticed the departing airplane rolling toward him. The pilot of the landing airplane attempted to veer out of the way of the departing airplane but was unsuccessful. The left wing of the landing airplane struck the left wing of the departing airplane. The landing airplane sustained substantial damage to both left wings, the fuselage, the horizontal stabilizer, and the elevator. The departing airplane sustained substantial damage to all four wings and the fuselage. Both pilots reported that there were no preimpact mechanical failures or malfunctions with the airplanes that would have precluded normal operation. Both pilots reported that neither made a radio call announcing their intentions.
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 CEN23LA197.
