and? Safety first, right? Eventually they’ll start servicing them properly.

Another procedure NOT approved by Boeing or SWA.

please expound. I was under the impression that it was an approved maintenance procedure to balance the hydraulic systems as long as it was performed by a mechanic. As far as pilots doing it, obviously not.

I’d like to see the MX reference. I’ve heard from a few in MX and Boeing that this isn’t an approved procedure. May be wrong and if it’s in the manual then great.

Still have the photo from one of our DHC-8s that landed with the parking brake set after doing that in the air, and forgetting the last step...

The following is from the JB internal forum. Of note, you need a baseline test, because the levels are all relative. After a suspected fume event, you quickly need to get another test to compare with baseline levels. If you get fumed and tested say 6 weeks later, the TCP will likely be out of your system, but the tissue damage will persist (but with no way to really test for it or link it to the fume event). Say you get fumed and tested and get results but you have no baseline? Well, it won’t tell you that much, as you need to compare it to something “normal.” I’ll try to find more info and post here.

Request these two blood tests from your doctor:

CHOLINESTERASE;SERUM
CHOLINESTERASE;RBC

I did it four months ago during my annual probing with my primary care doctor. They were completely covered by my health insurance but I don’t have the JetBlue health care discount program. I plan to have this done every year so that I accumulate an extensive history.

It is policy at Delta to write up any 737 that has had the hydraulics over-serviced or if a side is too high due to fluid transfer. Our max number 102%. I believe this policy was implemented after a study about what was causing fume events. Mtx also no longer fills above 100% because of this.
