herky400M Posted November 3, 2010 Share Posted November 3, 2010 Hello C-130 world; what is the procedure to check for bleedair leaks, airframe and engine. (149°C or 300°F) we are thinking to use a thermal camera to look for the possible problem. any other suggestions? :cool: Quote Link to comment Share on other sites More sharing options...
Nc97 Posted November 3, 2010 Share Posted November 3, 2010 A shredded rag attached to safety wire for checking bleed air leaks in the nacelle always worked for me... Quote Link to comment Share on other sites More sharing options...

True, also spraying the suspect area(s) with NDI penetrant developer will give you a good idea without the risk of a man-on-stand check Quote Link to comment Share on other sites More sharing options...
herky400M Posted November 4, 2010 Author Share Posted November 4, 2010 let me clarify, what I meant was the bleedair test on the aircraft ==> between engine and bleedairsystem,airco system, leading edge,connections on plumbing ect.. on the engine test stand, we put a man on the stand with the prop in discing and check with our hands or a thermoprobe greetz bob Quote Link to comment Share on other sites More sharing options...
pjvr99 Posted November 4, 2010 Share Posted November 4, 2010 Bob, no real difference to what I said. However, having had a few hours to think, your thermal camera idea may have a lot of merit ....... Quote Link to comment Share on other sites More sharing options...

Thermal cameras could be helpful in some cases. When the MC Shadows first got the FLIR we used to watch the wing leading edge heat up during the LE anti-ice checks. You could count the leading edge ribs even. Had one aircraft that the right outer wing continued to show warmer than the rest of the wing after the leading edge AI was turned off but didn't get an overheat. When we wrote it up, Mx told us the FLIR was not approved for troubleshooting and didn't follow up. About one week later it came back with a wing overheat, cracked expansion compensator right where the FLIR showed a hotspot. Mike Quote Link to comment Share on other sites More sharing options...
agarrett Posted November 4, 2010 Share Posted November 4, 2010 I guess its the attitude of the maintenance guys. The gunship maintainers actually used the IR on the other airplane to find a problem we were having while at Brindisi. Quote Link to comment Share on other sites More sharing options...
keepemflying130 Posted November 10, 2010 Share Posted November 10, 2010 Used our local CFR (Crash Fire Rescue) a few years back for their thermal camera for some LE leaks that eventually led to a faulty detector. Nice. Quote Link to comment Share on other sites More sharing options...
Herc 308 Posted November 10, 2010 Share Posted November 10, 2010 I have used a thermal camera a couple of times looking for bleed air leaks and had excellent results. doesn't work to well on a hot day. Darrell Quote Link to comment Share on other sites More sharing options...
