Carbon monoxide (CO) is a colourless, odourless and tasteless gas found in the exhaust gases of piston‑engine aircraft. Carbon monoxide detectors provide warning to aircraft occupants of the presence of CO levels in the cabin that are above safe concentrations. What happened On the afternoon of 31 December 2017, the pilot and five passengers of a DHC-2 Beaver floatplane, registered VH-NOO, boarded the aircraft for a charter flight from Cottage Point to Rose Bay, New South Wales. The aircraft taxied for about 7 minutes. Shortly after take-off, the aircraft deviated from the standard flight…

Safety summary Update This statistical report shows aviation occurrence and activity data over the 10-year period from 2010–2019 to provide an insight into current and possible future trends in aviation safety.

The primary mechanism for the prevention of carbon monoxide exposure to aircraft occupants is to carry out regular inspections of piston-engine exhaust systems to identify and repair holes and cracks, and to detect breaches in the firewall between the engine compartment and the cabin. What happened On the afternoon of 31 December 2017, the pilot and five passengers of a DHC-2 Beaver floatplane, registered VH-NOO, boarded the aircraft for a charter flight from Cottage Point to Rose Bay, New South Wales.
