  1. at sea level, a 0/low time compressor will make 80 to 85psi at normal ground idle. This increases 

    as throttle is advanced towards take off an TIT increases. The highest I have ever seen was 130psi.

    This was a 0 time engine where the CDP fell in "high" zone of the compressor graph. Compressor

    performance is based on OAT and pressure altitude.

  2. Cool. Ok start is perfect. LSGI looks like like a low time, very strong engine, but

    thats where things get hazy. NGI should be 580 to 600.

     

    After lights out TIT should be 740 to 780. It does look look like the FCU may have

    shifted rich, but you may also have a TD system cutting back too much fuel. Before

    messing with FCU, remove and inspect all thermocouples - replace as required. Make

    sure engine rigging is spot-on. Carry out  yellow box check.

     

    CIT bellows can be adjusted on flight line (if lead seal is still present on FCU) - 1 flat

    decrease (clockwise) is +- 25°C. This will affect the fuel flow across the entire

    schedule, so it may be necessary to reset NULL orifice.

     

     

  3. Static leak. 1st thing to do is remove RGB fwd mag plug and ADH bottom

    mag plug. Leave them open for 2hrs or so, then see which one is still

    dripping. If ADH, start by replacing P/S filter. After that replace main oil

    pump. 

     

    Lockheed Service News V18 N3 gives an excellent description of the 

    problem and trouble shooting

     

  4. ye i dont think system is de-activated. even though we dont have it on our birds, many QEC kits

    have the wiring and c/plug. It's a standard check for us in test cell if a new engine will not rotate

    when starter button is pressed to then turn on nacelle pre-heat. If it then rotates, we know the shop

    got the starter and  pre-heat c/plugs swapped around

  5. Dino, it sounds like you have a collapsing flexible line. Looks ok on the ground, but once oil is flowing through the inner wall is collapsing .

    Other possibility is the follower in the tank may be damaged. I have had this a couple times

    It don't appear to be an A model as it has fuel dump masts on the wing tips.  I can only see one drain mast on the bottom of the engines also as the A model has two drain masts.

    it is a C130B, redesignated C130BZ after glass cockpit, APU and 

    other upgrades and mods.

  7. Back to work yesterday, all is still well in the land of sand. People obeying

    the curfew, and while the infection rate may be troubling, situation is

    under control. Government doing a sterling job of getting a handle on

    the virus, getting free medical treatment for all, online distance learning 

    for schools, partial salaries guarenteed for companies that had to close.
