GTC problems 1 2
by mike in ca- 25 replies

I am having problems with a GTC not running without a boot pump. After the boost pump is turned off, about the time the manifold pressure gauge hits 5lbs the GTC dies. With a boost pump on the GTC will handle the load of the ATM and both AC packs on, the GTC will die with no load also as soon as the boost pump is turned off. I have checked the cracking pressure and it is at 61lbs, the armpit valve is working as it should. The gtc fuel filter was replaced and still no difference. Anyone ever had this problem?

J model props 1 2

It seems to me, from most of the pictures on this site, that the J's are parked with their props feathered. The other models are in, if I remember right, ground idle . Is this to keep the wind from turning the engines, since these props have six and in some cases eight blades and look like a food processor??? Inquiring minds want to know.... Giz

Manually draining refuel manifold 1 2
by Guest- 31 replies
- 11.9k views
I have heard many reasons why the manual says to drain the SPR manifold manually. I just wanted to throw this out there and find out why after you have already accomplished draining the roughly 200lbs of fuel with the drain pump the manual says to drain the residual into a container. It seems to me that the mere half gallon of fuel left in the manifold would be far fetch to call it a weight and balance issue. And the old a rock might burst the manifold open on t/o or landing is not actually going to get that small amount to spill anywhere. In reality the JP-8 we use would be much more volatile in a vapor form in that manifold to cause an explosion or fire of the sort…

Hello all, I am a new member and need some help getting information regarding the fuel system on C-130A models. I am a fuel cell mechanic and have worked C-130's for 13 years but the earliest models I have worked are B models. I would like to get an idea of the major changes done from A models as well as specifics of the original system. Any help is appreciated. Thank you

Hi guys A question arose the other day. We usually fly with max differential on our pressurization system. We set 1000' on the dial and then keep it until reaching max diff. That occurs around 19000' (don't have my dash-1 handy). We started discussing the benefits of that versus the stress on the fuselage. Anyone of you already discussed this subject, or is there even any guidance regarding the fact that we may fly with lower cabin pressure in order to ease on the fuselage? I know that the dash1 doesn't say anything about it but its common sense that the same number of cycles in fuselages that suffer max diff or "medium" diff will be different. Thanks

Hey guys, need some thoughts here. One of our birds is throwing a sh!t-fit, yawing to the left. Initially, props \'n engines were blamed, but after we changed the \'offending\' engine/prop combo and no result, the drawing board was called on. Since then, we have had all the control surfaces off, replaced the rudder, r/h aileron tab and l/h elevator tab. Also the aircraft was put through a full symmetry check. After todays FCF, the pilot told us he had to put in 7° rudder trim to stay straight after T/O, reducing to 4° for level flight, or do some serious pedal work. Also lined up torques at 14k and reduced #3 and #4 to 9400 before yawing stopped. Ai…

Someone at work mentioned some kind of Airforce wartime manual. Basicly what things you can do to get the plane going when your getting shot at. An example would be plugging bullet holes in the plane with sharpened bamboo sticks to allow pressurization. Does anyone know this manual I speek of? Also a J model specific book would be awesome. If anyone has a copy of either an H or J book id love to read through it. TIA

Hey all! I am looking for some information on a couple of subjects and thought that someone might know what I\'m talking about. First subject: Do any of you remember back a few years ago when we were having to move the pilots and copilots O2 walkaround bottles to the galley wall when installing flight deck armor? I am looking for the TCTO or OTI that bascially stopped us from doing this anymore. I noticed in the 00GE-00-1 under armor installation that the slick as removed this task, however, the T1, T2, and MC-P still have this listed as a task. I am trying to do a Form 22 to have this removed from the armor installation for these aircraft. Second subject: How about…

a prop question: 1 2 3

I have a question for the prop guys: as a crew chief, i was taught that when you feathered a prop,everything was shut off. hyd fluid,oil,elect,fuel, etc. A man by the name of Eric L Haney was a delta force operator and in his book,'inside delta force' he states that on that failed hostage rescue mission in iran in the middle of the desert in 1980, that the 130 he was on,'the engines continued to run,but the props were feathered'.All of my teaching says thats impossible. Or was he mistaken? Did they feather the props and he heard the GTC running? Would the crews even have shut down the eng's in that circumstance? Anyone know any extra info that they are allowed to share? …

Can anyone explain to me the logic behind the numbering of the overhead emergency hatches? Correct me if I am wrong, but why is #1 in the rear, #3 in the middle, and #4 above the flight-crew bunk? Why no #2?

Early in 1966, the Lockheed Tech. Rep. embedded withour squadron operating A Models, advised that a problem had arrisen in the operation of the static line retriever winch, and the company was keen to hear of any potential solutions. The reported problem involved a paratrooper remaining attached to the end of his static line, and the retriever winch being unable to draw the static lines, with dangling body, back into the aircraft. Aparantly, the aditional load (weight plus aerodynamic) caused the retriever winch line to whip abnormally and trigger the Rewind Limit Switch on the carriage of the winch, releasing the Rewind Relay. Repeated toggling of the Rewind Selector sw…

Who has the best aircrew discrepancies?
Last reply by PACAF, -
Just a few questions. The internal Benson tanks held approx 11,000 pounds? (WC-130H) How many gallons? Also why "Benson", was that the builder? Next, station 245 was measured from where? I seem to remember that it was somewhere in front of the nose. What station were the paratroop doors at? Last, any idea how much hyd fluid was in the utility system at any one time. In motion, not in the resevoir. Thanks Stoney

I am trying to find out what the minimum takeoff speed is for a c-130H without taking the time to do all the charts. I'd say with no load, minimum crew, and around 34k fuel.

Cargo door 1 2

Given the fact that there may be aircraft out there where the door will free fall and lock, is there anything in writing that requires it to do so? We can find nothing in any book that requires it to do so. All checks we perform and any mention of it in the -1 requires the switch to be set to the down position, which will lock this particular door.

We have a interphone problem that's been kicking our ass trying to track down so I figured I'd post here and see if anyone has any ideas we haven't tried. The Issue... We have a C-130 H2, Tail 87-9281 with a loud buzzing tone that is heard only in the Pilots, Copilots and Flight Intstructors stations. All other stations sound clear. The tone is heard regardless of which radios/nav systems are selected on the control box and volume panels. The tone in the bad stations goes away only when you press that call button, and only on the station which the call button is pressed. Troubleshooting... We have already pulled and swapped all the boxes and comm cords, doe…
