Firefighting plane in deadly Australia crash likely stalled: report
A C-130 tanker plane that crashed and killed all three Americans on board while fighting fires in Australia in 2020 likely stalled when flying in hazardous conditions after making a fire retardant drop, investigators said in a final report on Monday.
There is no evidence that the crew was told a smaller lead aircraft called a "birddog" initially assigned to support the C-130 had declined the mission due to weather-related safety concerns, highlighting a lack of information sharing that may have contributed to the crash, the Australian Transport Safety Bureau (ATSB) said.
"We do know that the use of large air tankers in Australia is relatively new," ATSB Chief Commissioner Angus Mitchell told reporters.
"And those policies perhaps haven't been as mature as they've been in other jurisdictions that have used them," he added, citing the US as being more advanced.
The Lockheed Martin Corp C-130 operated by private Canadian firm Coulson Aviation under contract to the New South Wales Rural Fire Service (RFS) was the biggest civilian plane by size to crash in Australia.
The January 2020 accident occurred during the country's worst fire season on record when RFS had up to 130 aircraft a day working to put out fires that killed 33 people and charred nearly 12 million hectares of land.
Coulson did not provide a pre-flight risk assessment tool for its firefighting large air tanker crews, ATSB said, while RFS had limited policies for aerial supervision requirements and no procedures for deploying tankers without aerial supervision.
Coulson has taken proactive steps to improve safety in response to the accident, including the introduction of a pre-flight risk assessment tool and new wind shear management procedures and training, though it has declined a recommendation to install windshear detection systems, Mitchell said. In the final report, Coulson said it did not believe wind shear detection systems would improve safety.
