Dont know about Gander ...... The SAAF back in the 80's did one in about 4hrs including

the engine run. 

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.

You will need to do a complete overtorque inspection of the QEC kit and truss mounts, and

also complete overtemp inspection and borescope the turbine, IGV and combustion liners

before attempting to start that engine again

I will try to do that next time, but what is the yellow box check, do you mean TD test set??

yes

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.

Excel file I made some time ago, performance accurate to about 0.2% most of the time.

Only thing I would add to pjvr99's response is consider resealing the low pitch stop too. I'd almost bet money the squeal check would fail.

yes, forgot about lps

bad valve housing, or internal leak from dome seals, pitchlock regulator, or

prop retaining nut seals

Also need LSGI and NGI TIT please

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 .....

no requirement for throttles to line up below cross-over: ONLY above

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

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

Yes, because it is flooding through the delivery nozzles and tubes as though the engine were running

Main oil pump: pressure regulator poppet valve has cracked

not sure why mech is ok, but it sounds like internal leak, maybe dome seals, pitchlock regulator

seals, prop retaining nut seals.

Anyone know where I can get a copy of overhaul/repair manual

for fuel flow transmitter PNo: 8TJ64GBW2

Thanx

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 .....

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.

Correct. Info at this time is they were starting up. 3 & 4 were running. When 2 was

rotated, the nose gear retracted

Seems like it. we'll wait for the BoI to figure it out ...

A/c 405 had a little oops at AFB Waterkloof this afternoon ....

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.
