Preliminary report

What NTSB knew early in the investigation. It may change in the final report.

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.
