The NTSB's narrative preliminary · quoted from the NTSB record
On September 2, 2025, about 1245 Pacific daylight time, a Gulfstream Aerospace G-V, N820MS, was substantially damaged when it was involved in an accident near Portland, Oregon. The pilot, co-pilot and passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The flight crew reported that, after landing at the Portland International Airport (PDX), Portland, Oregon, the airplane was taxied to a fixed-based operator to disembark two passengers and refuel the airplane. A passenger boarded the airplane, and the flight crew conducted a preflight of the airplane and prepared the airplane to depart. The pilot noted that after the no. 2 engine was started, there was a low indication from the hydraulic oil pressure gage. He activated the power transfer unit (PTU), and upon activation of the PTU, the nose landing gear retracted, and the forward fuselage impacted the ground. The forward pressure bulkhead sustained substantial damage. The flight crew conducted an emergency engine shut down and all occupants of the airplane exited the airplane through the aft baggage door. The airplane was secured for further examination.

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 WPR25LA273.
