So EASA found no reason in 2012 to specify in CS25 cabin air problems/solutions?
Let us hope that the EU Commission, having suddenly discovered engine oil is bad for ones health, may talk to EASA and ask them WTF are you lot up to?!
Oh, I forgot, our EU masters are far too busy limiting vacuum cleaner wattages and pondering hairdryers and other bits of domestic energy-consuming widgets for future diktats.
So their hard-pressed schedule will ensure the issue of toxic poisoning of crew and SLF is left on the back burner, pun intended!
