In 2013 Airbus warned of fume events from failure to clean environmental systems following leaks, and suggesting “A clean APU means clean cabin air.”
There are scores of Airbus narrowbody fume incidents across diverse carriers — including some fume occurrences leading to flight diversions and hospitalized passengers and crew — across JetBlue, Austrian, British Airways, American Airlines, Spirit, Lufthansa, easyJet, Aer Lingus, Jetstar, Germanwings, Turkish, Air France, Delta and others. And regulators may not be doing enough about it.
