Black Film On Inside Windows.

[silverbullet]

I've got a pilot complaining about black film on the inside of the windows of his Bell 206. The pilot is complaining about having to breath this stuff in all the time. I believe that this black film is exhaust comming from the engine. It must be comming into the cabin whenever the heater is on....

My question is: What can I do to stop this Black crap from comming into the cabin? Any sugestions would gladly be taken. Thanks.

If you have exhaust from the engine coming into the cabin, ground the aircraft immediately and find/fix the source of the leak.

You waana see soot....... I scrape it of my face (big time), every day after logging in the crane. :shock:

Carbon Monoxide indicators are inexpensive and easy to install.

I believe Helifor had a study done on the partculate matter (soot), and it was deemed not a health hazard.....I will try to find out who did the study.

That black soot is pretty normal in Jetranger, just accumulates after a while from the downwash/exhaust and is attrached by the static build up on the windows.

Ahhh.... What kind of heaters are installed???

if its casey heaters, take a good look for any cracking or chafing of the engine exhaust duct allowing the exhaust to permeate into the heater system. you could also be seeing a breakdown of the heater tubing....

 

if it's a janitrol, wash it with gasoline, high grade, and dry it with a match.

If the liner is cracked it can mix with fresh air. H

Was the author of the study "Dr. Duke solomon, an agent to the Shell oil company"? :lol:

Thank you for all your advice. Much appreciated.

Well known problem on the 206s. See TB 206-92-143 for Bell's solution. Bit of a pain to install, but I think it's worth it now that (basically) only Jet A is all that is available..........
