If you are an employee and on bluepilots you would be wise to read the 65 page thread on fumes. Several JB pilots are out now, one almost died and won’t ever fly again. TCP is a neurotoxin. It may smell like dirty socks/dirty packs, or with the new oil magic marker, but it’s nasty stuff. Some British airways pilots have died, a spirit pilot died, and who knows how many others have had neurotoxic issues undiagnosed to unlinked to a fume event. It causes neuro issues, cardiac issues, depression, and all sorts of weird stuff. Aerotoxic.org has some good info. There’s a reason the pilot union for 5 UK airlines just filed a lawsuit against each airline for not dealing with it.
Airbus engines (at least the IAEs, dunno about the CFMs), run at a much higher oil pressure than other engines, and is the assumed reason it has a higher rate of dirty sock smell. There were 59 fume events reported in March. Only one of those was an embraer. Only a few were 321s. The rest were 320s. If it was a work action or made up, you’d see events in the 190 and certainly the 321 in a statistically similar manner. But the 321s are all new and the seals not worn out like the older 320s.
It’s real. PAX aren’t exposed as much as flight crew, and it’s thought to be a cumulative exposure/absorption. And it doesn’t have a “fumey” odor. It’s pretty benign compared to other fumes/odors (electrical, chemical, fuel, exhaust, etc). Of the 59 events in March, only maybe a couple made the news. Most pax (and even ignorant pilots) don’t know anything/much about it. I hope saabstory isn’t a JB employee, or if he is, he educates himself.
