The NTSB's narrative preliminary · quoted from the NTSB record
On August 17, 2025 about 1521 Pacific daylight time, a Cessna 140, N89447, was involved in an accident near Shelter Cove, California. The student pilot was fatally injured, and the passenger sustained serious injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The flight departed Shelter Cove Airport (0Q5), Shelter Cove, California, and was destined for Charles M Schulz-Sonoma County Airport (STS), Santa Rosa, California. A witness located near the airport reported that the airplane departed runway 12 and made a steep climbing right turn over the ocean into low coastal fog, and the airplane disappeared from view. Shortly thereafter, he heard sirens and someone calling for help in the water. The passenger reported that they flew to 0Q5 for lunch and were returning to STS. He stated that they departed to the south, into the wind, and intended to circle the airport and fly over the runway to gain altitude. He stated that after they took off, they made a right turn northbound over the ocean and entered fog. The passenger noted that he could see the water below them and that it was closer than expected. Shortly after entering the fog, he described the feeling of turbulence and stated the airplane was “violently pushed down” and then it impacted the water. He did not remember exiting the airplane after the impact. First responders transported the occupants by personal watercraft to shore. The wreckage has not been recovered.

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 WPR25FA257.
