  1. 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.
  2. Excel file I made some time ago, performance accurate to about 0.2% most of the time. Perf PPC v2.1.xlsx
  3. bad valve housing, or internal leak from dome seals, pitchlock regulator, or prop retaining nut seals
  4. Also need LSGI and NGI TIT please
  5. what is NULL start TIT? what is TIT before correction light out? what is rich/lean? where is NULL orifice set? I need exact numbers .....
  6. no requirement for throttles to line up below cross-over: ONLY above
  7. 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
  8. 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
  9. Yes, because it is flooding through the delivery nozzles and tubes as though the engine were running
  10. Main oil pump: pressure regulator poppet valve has cracked
  11. not sure why mech is ok, but it sounds like internal leak, maybe dome seals, pitchlock regulator seals, prop retaining nut seals.
  12. Anyone know where I can get a copy of overhaul/repair manual for fuel flow transmitter PNo: 8TJ64GBW2 Thanx PJ
  13. Question for the test cell guys: when checking light house breather pressure, did you ever get negative (below 0"Hg) readings? T56-56 says should be 0 to 11"Hg .....
  14. 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 is a C130B, redesignated C130BZ after glass cockpit, APU and other upgrades and mods.

    Correct. Info at this time is they were starting up. 3 & 4 were running. When 2 was rotated, the nose gear retracted

    A/c 405 had a little oops at AFB Waterkloof this afternoon ....
  20. 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.
  21. Company ordered all 55 and older to stay home for 2 weeks + several others that had been to high risk countries before the government suspended all international flights to and from Saudi Arabia. So far, not too bored ...
  22. installation effect always 100%
