CASA has released some advisory information regarding Carbon Monoxide Poisoning. Please have a read and talk to your Maintenance provider
The exhaust collector assemblies on piston powered aircraft are a known source of CO. Manufacturer’s instructions for continued airworthiness (ICA) require regular inspection of exhaust pipe collectors and heat exchangers. Their useable life is centered on an “on condition” maintenance inspection philosophy and as such requires increased vigilance with ageing exhaust components.
‘On-condition’ – ‘On-condition’ maintenance means an inspection/functional check that determines an item’s performance and may result in the removal of an item before it fails in service. It is not a philosophy of fit until failure or fit and forget. The process of ‘on-condition’ maintenance is applied to items on which a determination of their continued airworthiness can be made by visual inspection, measurements, tests or other means without disassembly inspection or overhaul. The condition of an item is monitored either continuously or at specified periods. The item’s performance is compared to an appropriate standard to determine if it can continue in service
