Investigator blames exhaust leak for Sydney seaplane crash

Consequently, the investigation found that it was likely that this significantly degraded the pilots ability to safely operate the aircraft. The crash occurred during a joy flight on New Years Eve when the plane flew low into Jerusalem Bay, which is surrounded by steep terrain, and crashed into the Hawkesbury River. The crash investigator said the plane likely stalled while turning in the bay before crashing.

A pilot was confused and disoriented from inhaling poisonous fumes in the moments before his seaplane plunged into a river near Sydney in 2017, killing him and his five British passengers, a crash investigation found Friday.

Canadian pilot Gareth Morgan, 44, and the passengers had elevated levels of carbon monoxide in their blood. Investigators found cracks in the exhaust system of the DHC-2 Beaver plane that was built in 1963 and bolts missing from a firewall that would have allowed carbon monoxide to leak from the engine bay into the cabin.

"The pilot would have almost certainly experienced effects such as confusion, visual disturbance and disorientation," Australian Transport Safety Bureau Chief Commissioner Greg Hood said in a statement. "Consequently, the investigation found that it was likely that this significantly degraded the pilot's ability to safely operate the aircraft.''
