A helicopter conducting water-bucket drops on a wildfire near Mariposa, California, crashed on September 20, 2026, killing both people aboard, and the National Transportation Safety Board is now leading the federal investigation into what brought it down. The Federal Aviation Administration confirmed in a statement that the aircraft, a Eurocopter AS332L1 Super Puma, went down around 2:55 p.m. local time while working the Dome Fire southeast of Ostrander Lake inside Yosemite National Park.
The two pilots killed have been identified as Greg King, of Alaska, and Ryan Cutter, of Utah, according to statements from their employer and Alaska’s state wildfire agency. Both men worked for Precision, the Oregon-based aviation contractor operating the helicopter under a firefighting contract at the time of the crash.
What the FAA has confirmed so far
In its own statement on the crash, the FAA said plainly that “the FAA and National Transportation Safety Board (NTSB) will investigate,” adding that “the NTSB will lead the investigation,” the standard division of labor for a fatal civil aircraft accident in which the FAA documents the scene and regulatory history while the NTSB determines probable cause. Neither agency has released a preliminary finding on what caused the AS332L1 to go down, and reporting on the crash has noted that investigators will need to examine wreckage distribution, conduct an engine and gearbox teardown, and review rotor and drive continuity alongside fuel state, weather conditions and crew duty records, a process that typically unfolds over several months before a preliminary report is issued.
The crash occurred while the helicopter was making a water drop, one of the more hazardous phases of aerial firefighting because it requires flying at low altitude and reduced speed, often in smoke-degraded visibility, to place water exactly on an active fire edge. Neither the FAA nor the NTSB has said whether smoke, terrain or a mechanical issue played a role in the accident.
The AS332L1 Super Puma is a heavy twin-engine helicopter originally designed for offshore oil-platform transport before variants were adapted for utility and firefighting work, and it is capable of carrying a much larger water load than the light single-engine helicopters more commonly seen on smaller wildfires. Contractors like Precision typically operate the type under exclusive-use or call-when-needed agreements with state and federal fire agencies during peak wildfire season, meaning the aircraft and its crew would have been assigned to the Dome Fire specifically rather than flying an ad hoc mission.
The Dome Fire and the operation the crew was flying
The Dome Fire started September 15, 2026, in the Mariposa County area and had grown to more than 3,400 acres with 15 percent containment by the Monday evening after the crash, according to CBS Sacramento’s reporting on the accident. Precision’s helicopter was one of the aircraft assigned to slow the fire’s spread inside Yosemite National Park when it went down, and the loss of the aircraft came at a point in the fire’s timeline when containment remained limited and additional aerial resources were still actively engaged.
Precision issued a brief statement following the crash, saying it was “devastated by this loss” and struggling to find words, and asking for “privacy and compassion” for the families of the two pilots and for its own staff as they grieve. Alaska’s Division of Forestry and Fire Protection, which had worked alongside King on wildland fires in the state, said in its own statement, also carried in coverage of the crash, that he “was a cherished member of [the agency’s] wildland fire family, having served on wildland fires in Alaska and extensively alongside the Division of Forestry & Fire Protection.”
An investigation still in its earliest phase
Because the crash happened only days before this report, the NTSB’s work remains in its earliest, fact-gathering phase, and neither agency has scheduled a date for a preliminary report. Federal investigations into fatal firefighting aircraft accidents typically produce a short preliminary report within roughly a month that establishes basic facts without assigning cause, followed much later by a full report identifying probable cause, meaning the public account of exactly what happened over Mariposa is likely to remain incomplete for some time.
Precision said, in comments reported by Fox Weather, that it is cooperating with the FAA, the NTSB and fire agencies involved in the response as the investigation proceeds. The company has not said whether it has grounded other aircraft in its firefighting fleet pending the outcome, and neither the FAA nor the NTSB has indicated whether the accident will prompt any broader review of water-drop procedures used across the aerial firefighting contracts supporting the Dome Fire response.
For the Dome Fire itself, the crash removed one aircraft from an active firefighting operation that was still working toward full containment when it happened, though officials have not said the loss materially slowed the broader response. What remains open, beyond the eventual NTSB determination of cause, is whether the accident changes how contractors and fire agencies schedule water-drop missions on fires burning inside terrain as steep and heavily forested as the stretch of Yosemite National Park surrounding Ostrander Lake.
