CALIFORNIA / RankWire.AI / – Two individuals lost their lives after a firefighting helicopter crashed within Yosemite National Park during efforts to combat the Dome Fire. The Eurocopter AS32 went down in Mariposa County around 2:55 p.m. on September 20. The aircraft was supporting firefighting crews in rugged terrain when the accident occurred. Federal aviation officials confirmed the fatalities of both people onboard. The crash happened near the Ostrander Lake area, as aerial resources contributed to the larger firefighting operation.
Precision Helicopters identified the pilots as Greg King and Ryan Cutter. Both were engaged in wildfire suppression at the time of the crash. King had extensive experience supporting wildland fire operations and had worked with firefighting teams in Alaska on various missions. The Alaska Division of Forestry and Fire Protection acknowledged his longstanding involvement with its efforts after the incident. Precision Helicopters also verified Cutter’s identity following notifications to his family members.
Authorities stated that the helicopter was performing water bucket operations before the crash. Aircraft like this support firefighters in Yosemite, especially in areas with steep terrain that hinder ground access. Their tasks include water drops, transporting personnel, and delivering supplies. Hundreds of firefighters have been working on containment lines around the Dome Fire. The crash marked a tragic aviation incident amid an already complicated wildfire response involving crews, aircraft, and backcountry operations.
Dome Fire Continues to Grow in Yosemite
As of September 22, the Dome Fire covered 3,420 acres and was 15% contained, according to California incident updates. The wildfire started on September 15 north of Wawona Dome in Yosemite National Park. Its cause remains undetermined. Firefighters face challenges from heavy ground fuels, timber, and difficult terrain while working on the fire perimeter. Natural granite formations and areas burned by previous fires also surround the ongoing efforts to suppress the blaze.
On September 21, the National Park Service reported 581 personnel assigned to the incident. Crews worked to build and reinforce containment lines across remote park sections. They also tackled spot fires and dense fallen vegetation. Aircraft provided water drops and logistical support to ground teams operating in the affected areas. Most of Yosemite remained open, though closures persisted near the active fire zone and surrounding backcountry routes.
Investigators Probe the Fatal Helicopter Crash
The National Transportation Safety Board and federal aviation authorities are investigating the crash. No cause has been officially announced. Federal records identify the aircraft as a Eurocopter AS32 involved in firefighting operations near Mariposa. Investigators are expected to examine the wreckage, flight data, and other available evidence as part of the investigation. There is no link yet established between the crash and weather, mechanical issues, or any other specific factor. Authorities have not determined what caused the aircraft to go down.
Fire restrictions and closures continue across parts of southern Yosemite as firefighting efforts go on. Officials closed the Ostrander Lake Trail and the areas south of it. Trails around Chilnualna Falls and other backcountry routes remain affected. No evacuation orders or warnings have been issued, according to the latest park updates. Firefighters remain focused on suppression while investigators look into the deadly helicopter crash that claimed the lives of King and Cutter during the California wildfire response.
