Agree, BALPA need to stop hovering on the side lines and get their hands dirty on this one. They are probably worried about the amount of cash it will cost them while persuing airlines and manufacturers in the courts. Got to finance head office and annual delegates conferences etc.
At a recent reunion of a defunct operator of the 146 I was shocked to hear of a number of pilots who are seriously ill following years of exposure to organophosphate poisoning. I consider myself lucky in hindsight for having only flown the 146 for a year. However the Airbuses that I now fly still exhibit the same old tell tale smell from time to time on aircraft over 3 to 4 years old, so the 146 is not the only culprit. Good preventative maintenance can control it but that costs money.
The IPA are showing far greater interest in this subject than BALPA, one of a number of reasons for which I will soon be increasing my salary by 1%.
