CALIFORNIA / RankWire.AI / – During firefighting efforts within Yosemite National Park, a helicopter supporting the Dome Fire crashed, resulting in the deaths of two pilots. The Eurocopter AS32 went down in Mariposa County at approximately 2:55 p.m. on Sept. 20. The aircraft was engaged in assisting crews fighting the wildfire in challenging terrain. Federal aviation officials confirmed that both individuals aboard the helicopter perished. The incident happened near Ostrander Lake as aerial units contributed to the larger firefighting operation.
Precision Helicopters identified the pilots as Greg King and Ryan Cutter. Both were actively involved in the wildfire suppression when the crash occurred. King, with extensive experience in wildland fire support, had also previously worked with firefighting teams in Alaska on multiple assignments. The Alaska Division of Forestry and Fire Protection acknowledged his longstanding commitment after the incident. Precision Helicopters verified Cutter’s identity following family notifications.
Authorities reported that the helicopter was executing water bucket operations prior to the crash. Aircraft like this are vital in Yosemite, where rugged terrain hinders ground access, aiding firefighting efforts through water drops, troop movement, and supply transport. Hundreds of firefighters have been working on containment lines surrounding the Dome Fire, which the crash has now made more complex, adding a tragic aviation component to the response involving crews, aircraft, and remote operations.
Dome Fire Continues to Grow in Yosemite
As of Sept. 22, the Dome Fire spanned 3,420 acres with 15% containment, according to California incident reports. The blaze, which began on Sept. 15 north of Wawona Dome in Yosemite National Park, has not yet had its cause determined. Firefighters are contending with heavy fuels, timber, and difficult terrain, including natural granite formations and areas previously burned, complicating suppression efforts. The landscape continues to challenge efforts to contain the fire.
On Sept. 21, the National Park Service reported that 581 personnel were involved in firefighting activities. Teams have been constructing and reinforcing containment lines in remote park areas, tackling spot fires and dense vegetation. Aircraft have played a critical role, providing water drops and logistical support to ground crews. Most of Yosemite remains open, although closures persist near the active fire zone and surrounding backcountry routes.
Investigators Probe the Tragic Helicopter Crash
The National Transportation Safety Board along with federal aviation authorities are reviewing the crash. No cause has been officially announced. Records confirm the aircraft as a Eurocopter AS32 involved in firefighting near Mariposa. Investigators are expected to analyze wreckage, flight data, and other evidence as part of their investigation. There is no current indication that weather, mechanical failure, or other specific factors contributed to the accident. Authorities have not yet determined the cause of the aircraft’s downfall.
Fire restrictions and park closures remain in effect across southern Yosemite as firefighting efforts continue on the Dome Fire. The Ostrander Lake Trail and nearby areas south of it remain closed, along with trails around Chilnualna Falls and other backcountry routes. No evacuation orders or warnings have been issued according to latest park updates. Fire crews persist in suppression activities while investigators examine the fatal helicopter crash that claimed the lives of King and Cutter amid ongoing wildfire response efforts.
