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 ...

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.

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 ...

installation effect always 100%

We frequently exceed duty cycle during comp wash without losing starters. I do not believe shorter motoring time
will have any effect as the highest load will occur at the start of rotation. Yes, 2J-T56-101CL-1 requires dry-out
run within 4 hours. If not, the rinse procedure must be redone.
-
TO's tell us 1 minute ON, 1 minute OFF, 1 minute ON, 5 minutes OFF, 1 minute ON, 30 minutes OFF ......
Having said that, a starter can fail at any time. I have had the starter shaft shear on 1st attempt, it has
also sheared at 40% during normal starting. During compressor wash, the load on the starter is more than
doubled so it has a much greater chance of failing. I don,t think there is much to be done in terms of
extending life beyond what we already do .....
We follow a slightly modified procedure to what is stated in 2J-T56-101CL-1:
Allow detergent mix to enter engine until it is flowing from intake, then motor engine for 1 minute, allow
minimum 5 minutes soak time (or move on to next engine).
Open the rinse water and wait for clean water to flow from the intake, motor engine for 1 minute, wait 1 minute
or move on to next engine. Keep doing this until clean water is coming out of turbine. During the last motoring,
stop the water at +-30 seconds but keep motoring until 1 minute to vent excess fluids. Complete dry-out run
withing 4 hours

Dont forget about the 6 L100-30s and the 4 L382C/C130 of the Saudi Airforce.

C130, tail number 403, has crashed at Goma, DRC. All on board ok. Still
waiting for more info
T56 -A-7B eng oil leakage from diff places.
in C-130 Technical

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
