silverbullet Posted January 25, 2008 Report Share Posted January 25, 2008 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.

ray Posted January 25, 2008 Report Share Posted January 25, 2008 If you have exhaust from the engine coming into the cabin, ground the aircraft immediately and find/fix the source of the leak. Quote Link to comment Share on other sites More sharing options...
Helilog56 Posted January 25, 2008 Report Share Posted January 25, 2008 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.

kopterdoc Posted January 25, 2008 Report Share Posted January 25, 2008 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. Quote Link to comment Share on other sites More sharing options...
Hazy Posted January 25, 2008 Report Share Posted January 25, 2008 Ahhh.... What kind of heaters are installed??? Quote Link to comment Share on other sites More sharing options...
TwistedSpar Posted January 25, 2008 Report Share Posted January 25, 2008 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.

Was the author of the study "Dr. Duke solomon, an agent to the Shell oil company"? :lol: Quote Link to comment Share on other sites More sharing options...

Cambox Posted January 28, 2008 Report Share Posted January 28, 2008 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.......... R...
