CALIFORNIA / RankWire.AI / – A tragic helicopter crash during firefighting operations in Yosemite National Park resulted in the deaths of two pilots. The Eurocopter AS32 went down in Mariposa County at approximately 2:55 p.m. on September 20, while supporting efforts against the Dome Fire. The aircraft had been aiding crews tackling the wildfire in rugged terrain. Federal aviation authorities confirmed that both individuals aboard the helicopter lost their lives. The accident took place near the Ostrander Lake region as aerial units contributed to the broader firefighting strategy.
Precision Helicopters identified the pilots as Greg King and Ryan Cutter. Both men were engaged in wildfire suppression when the crash occurred. King possessed extensive experience in flying support missions for wildland fire operations and had worked multiple times with firefighting teams in Alaska. The Alaska Division of Forestry and Fire Protection acknowledged his long-standing involvement in firefighting efforts after the incident. Precision Helicopters also verified Cutter’s identity following notifications to his family members.
Preliminary reports from authorities indicate the helicopter was performing water bucket operations prior to the crash. Aircraft like this play a critical role in supporting firefighters across Yosemite’s steep terrains, where ground access is limited. Their tasks have ranged from water drops and moving personnel to delivering supplies. Hundreds of firefighters have been engaged in establishing containment lines around the Dome Fire. The accident has introduced a fatal aviation incident into an already complex wildfire response, which involves crews, aircraft, and backcountry operations.
Dome Fire Continues to Grow in Yosemite
As of September 22, the Dome Fire extended to 3,420 acres and was 15% contained, according to current California incident data. The wildfire ignited on September 15 north of Wawona Dome within Yosemite National Park. The cause of the fire has yet to be determined. Firefighters have faced challenges posed by dense timber, heavy ground fuels, and rugged terrain while working around the fire’s perimeter. The landscape is characterized by natural granite formations and areas previously burned, complicating suppression efforts.
The National Park Service reported that 581 personnel were assigned to manage the incident as of September 21. Crews persisted in constructing and reinforcing containment lines across remote parts of the park. They also responded to spot fires and areas with thick fallen vegetation. Aircraft provided essential water drops and logistical support to ground teams operating in the affected zones. Most of Yosemite remained open, though closures persisted near the active fire zone and backcountry routes surrounding the area.
Investigation Continues into Fatal Helicopter Crash
The National Transportation Safety Board along with federal aviation authorities are conducting an investigation into the helicopter crash. No cause has been publicly 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. So far, authorities have not linked the crash to weather conditions, mechanical issues, or any other specific factors. No official determination has been made regarding the cause of the aircraft’s descent.
Fire restrictions and closures remain in effect across parts of southern Yosemite as firefighting efforts continue on the Dome Fire. The Ostrander Lake Trail and areas south of it are closed, along with trails around Chilnualna Falls and other nearby backcountry routes. Authorities have not issued any evacuation orders or warnings in the latest park updates. Firefighters persist with containment work while investigators scrutinize the tragic helicopter accident that claimed the lives of King and Cutter during California’s wildfire response.
