I'm betting on bleed valves being wet.... With smoke in cabin......

IS the oil coming out of the drainmast? If so look at your scavenge back pressure.

Had the same thing happen on decent with  an "A" model. Engine shop signed it off as "could not duplicate".I wasn't happy!Next flight when we began the decent I was in the cargo compt.Oil was streaming from the mast.Engine was shut down and air started just before entering the pattern.Problem was found to be a relief valve keeping the oil tank pressurized on decent pushing the oil out.R/R and all was good.

      Hi everyone,
      After seeing this video, I have some questions.
      I know that the turboprops of the Herc are constant speed ones, meaning the pitch of the blades is adjusted in order to gain speed.
      In the video above, a Fat Albert is going through startup procedures. At 0:05 engine No.3 starts up and at 0:43 it seems like the engine is at idle speed. Then at 0:46 the engine increases its RPM which can be heard and seen.
      This startup procedure is repeated for the engines No.4, No.2 and No.1.
      When the video reaches 2:11, the engines somehow decrease their RPM. And with this RPM, the Fat Albert starts to taxi.
      Is there some kind of switch to increase and decrease the RPM of the engines?
      And what is the use of this increase and decrease of RPM?
       
      I hope to hear from someone soon.
      Kind regards,
      C-130Hercules

      Hello my name is Maarten, I am a Belgian last year high school student: aircraft technology. For my graduation I have to write a paper about the eingines of the C-130 Hercules. I've found a lot of information about the Allison T56 but it's more difficult to find the wright information about the Rolls Royce AE2100 engine. I need to know the differences between those two engines so I can compare them with each other. Do you know websites I have to visit or can you tell me somthing about those engines, any kind of information is welcome. If someone can help me with it I will be most thankful.

      Grtz Maarten
