A seaplane crash which killed six folks was seemingly brought on by engine fumes that leaked into the cabin, a coroner has discovered.
The Sydney Seaplanes DHC-2 Beaver nosedived into the Hawkesbury River north of Sydney throughout a sightseeing journey on New Year’s Eve, 2017.
The crash claimed the lives of pilot Gareth Morgan and 5 passengers — high-profile British businessman Richard Cousins, his two grownup sons, fiancee Heather Bowden-Page and her 11-year-old daughter.
Air crash investigators beforehand revealed Mr Morgan had elevated ranges of carbon monoxide in his blood on the time the aircraft hit the water.
NSW Deputy State Coroner Derek Lee on Friday discovered cracks within the plane’s exhaust collector ring allowed gases with excessive carbon monoxide concentrations to go into the cabin.
“It is most likely that holes in the magneto access panels left open by three missing bolts and gaps around an incorrectly oriented magneto access panel provided the route of entry,” Magistrate Lee stated.
Exposure to carbon monoxide within the cabin impaired the pilot’s means to function the plane safely, the Justice of the Peace added.
The findings observe a 2021 report by the Australian Transport Safety Bureau (ATSB) which put collectively the plane’s last actions.
The anticipated flight path ought to have seen Mr Morgan taxi away from Cottage Point, take off and switch east to realize altitude over the Hawkesbury River.
Instead, he turned northwest and, flying beneath the peak of the mountainous terrain, entered Jerusalem Bay and made a pointy right-hand flip earlier than the aircraft dropped nose-down into the water.
Carbon monoxide toxicology testing discovered he and all passengers had elevated ranges of carboxyhemoglobin.
Investigators then discovered pre-existing cracking within the seaplane’s engine collector ring, which may result in exhaust leakage, and a breach within the aircraft’s firewall, which might enable gases from the engine bay to enter the cabin.
Magistrate Lee really helpful that carbon monoxide testing be routinely carried out for all deaths ensuing from airplane crashes.
He described the sudden and sudden deaths of six folks in a single occasion as “truly heartbreaking”.
