Aircraft: Air Conditioning

Question

To ask Her Majesty’s Government, further to the Written Answer by Lord Ahmad of Wimbledon on 20 June (HL503), on what basis they state that European Aviation Safety Agency certification standard 25.1309c does not require warning systems for engine oil that leaks onto hot aircraft engines over which cabin "bleed air" is drawn.

Answer

The European Aviation Safety Agency (EASA) certification standard CS 25.1309c requires a warning only in the case where an unsafe condition requires immediate corrective action by the flight crew.

By virtue of the engine manufacturer’s compliance with certification standard CS E.510 for the engine, the aircraft manufacturer is able to demonstrate that an unsafe condition requiring immediate corrective action will not exist under CS 25.1309c. Ensuring compliance with these requirements is the responsibility of EASA.
