MARIN COUNTY, Calif. (KRON) — Two people were found dead at a crash site after a small airplane went down in the Marin Headlands Friday afternoon, according to a tweet from the Golden Gate National Park Service. The plane crashed at approximately 12:09 p.m. and an emergency beacon was activated about two minutes later, the Marin County Sheriff’s Office said.

A search determined the crash site to be on a backcountry ridge north of Conzelman Road, away from roads and trails, the Golden Gate Park tweet stated. The Federal Aviation Administration confirmed the aircraft as a single-engine 2017 Vans RV-10 in a statement to KRON4.

Visitor access to the Marin Headlands or traffic are not affected at this time, according to the Park Service. The crash site is closed for the investigation and the area is obscured by fog, the Park Service tweeted.

An interagency team including the National Park Service, the FAA and the National Transportation Safety Bureau is leading the investigation. The NTSB is in charge of the investigation and will provide additional updates, the FAA told KRON4.

“After investigators verify the aircraft registration number at the scene, the FAA will release it,” the FAA told KRON4. The information will be released, usually on the next business day, on this website: asias.faa.gov/

To facilitate removing the aircraft, Conzelman Road and McCullough Roads will remain closed Saturday to vehicles and bicycles.
