Aircraft: Air Conditioning

Question

To ask Her Majesty’s Government, further to the Written Answer by Lord Ahmad of Wimbledon on 27 April (HL7764), whether or not European Aviation Safety Agency certification standard 25.1309c, which requires warning systems for any unsafe operating system, applies to engine oil that leaks onto hot aircraft engines over which cabin "bleed air" is drawn.

Answer

European Aviation Safety Agency certification standard 25.1309c does not require this. However the European Aviation Safety Agency (EASA) standard for engine certification, CS-E 510, requires that a failure analysis and safety assessment is conducted by the engine manufacturer to show that hazardous concentration of toxic products will not enter the cabin bleed air.

EU airlines are legally required to report any potential safety incident including where fumes or smoke are detected on board an aircraft. Although these incidents are rare, these reports are taken very seriously and reviewed thoroughly to identify any safety issues or trends.

Passenger and crew safety is of paramount importance. The Department for Transport and the Civil Aviation Authority are constantly working to enhance safety standards.
