Peculiar, jet exhaust does not seem to generate dramatic malignancy rates in the civil arena afaik. Do helicopters use some special sauce such as the phosphate lubricants seen as an issue in bleed air?
This is also being discussed on the Rotor site. The discussion there is focused on the winchman being in the open door during rescue operations. Civilian operators typically don't do winching operations

I understand that the focus of this is specific to the Seaking due to the engine exhaust / airflow combination which apparently created a particularly hazardous environment for those working in the door.
They were effectively sitting in the exhaust flow for long periods of time.
The exhaust gas path / airflow on other helicopters will be different (which is not to say that there may not still be a risk) but this particular case is based on Seaking (and evidence that UK MOD were aware of health risks to crew operating in the door).
As i understand it the 146 issue is suggested to be from contaminated cabin air from the engine bleeds containing chemicals from the engine oils.
In the seaking case it is from breathing in the exhaust gases.
Whilst they may seem similar (and in fact may be similar) there are potentially significant differences as well. The bleed air gases in the 146 will not have been subject to combustion whereas the Seaking exhaust has - This will change the nature of what is being breathed.
Which is not to downplay the seriousness of either but they are not necessarily the same.
Also, I've not heard of Myeloma being diagnosed or reported as resulting from the 146 issues ( I stand to be corrected if it has been identified as arising from the contaminated air).

Interesting considering we used to operate and start Jags in a HAS, you would have two in there and as they were designed for single aircraft the jet eflux didn't go out of the blast doors at the back, only one engine was close. Your eyes were streaming as you were breathing it in.
A known hazard for many years. The HT leads in the radar Tx/Rx, immediately behind the intake fan, used to get caked with half an inch of eflux and cause corona discharge. You can imagine what that **** would do to your lungs.
Just a point of pedantry, the crewman most at resk would be the Winch OP, not the Winchman.
Oddly, this has raised interest, but a recent (3 days ago) report on the Beeb news page of a Reaper driver suffering PTSD, hasn't prompted comment.

The implications of mists / fumes etc on human biology still remain very uncertain, for example myeloma, sarcoma, non hodgkins lymphoma seem to have some similarities interms of having some environmental precursors. Personally i feel the proper and systematic examination of cancer / neurological condition prevelance in aircrew is long overdue. Just look back through PPrune and see the number of obituaries that list cancer and it can't all be down to hard living in the mess or on det.

I’m also a fellow sufferer and I would love to know how widespread Myeloma is amongst the aircrew fraternity and whether there is a link.
