But once it’s in the system, it’s a very comprehensive tear down/cleaning and takes a lot of time. Sometimes the planes get a lot of attention, but there are a lot of repeat write-ups and the problem obviously doesn't get fixed. Oftentimes they clean some oil and just do engine runs, only for it to happen again later. 59 fume events in March. That’s 2 a day. Average is 5 a day worldwide. No, I don’t think the number of events has decreased. As awareness increases (especially with the new magic marker smell which a lot of people couldn’t identify as toxic fumes), more that would have gone unreported get reported. B6ALPA is supposedly making a committee to study it, but has been pretty mum. Airbus/IAE need a fix. Until lawsuits/deaths result and are positively linked to this issue, not much will change.
