Question for you guys. I have a c130h transferring fluid from the aux system to the utility system. Ive replaced the Ground test valve and the utility system accumulator (which had a leak internally). Neither of those parts solved it and it is still happening. Thoughts on where to go from here?

Hello! We’ve recently ran into an issue on our C130J with a get home control panel lighting. The panel lights up and is fully operation with external power, however on just battery power the lighting is inop. It will still transmit, but the lighting is completely inop. We’ve ohms checked most associated wiring good, swapped get home control panels, BAU, as well as the emer lighting module to no avail. anyone have any experience with something similar or have any input? thanks!

We are experiencing a bit strange problem of single disc (mark-1) brakes not holding B-model aircraft at and above cross-over setting on all four engines. It is happening both in case of parking and pedal pressure braking. It is understood that single disc brakes were designed for T56A7 engines having take-off TIT of 970 whereas subject B-model is fitted with T56A15 engines having take-off TIT of 1085 (thus more torque). Brake assemblies, brake control valves, brake selector valves, brake accumulators, shuttle valves, relief valve have been replaced. Brake pressures have been found normal (1700-1800 psi in case of pedal pressure and 1500-1600 psi in case of parking brake)…

Hi Folks, great website here. I was wondering if anyone had some wording about the brake system, specifically the Description & Operation. I know the pilots press on the brake pedals and the plane slows down, but what happens in between? What sequence of events between the force of the brake pedal and the brakes operating? Thanks very much in advance!!

Hi folks. Looking to verify something I was told recently about SEA vintage C-130s. Was it possible to lower the ramp/open the cargo doors in flight from the flight deck? If so, would that have been done by one of the pilots or the FE? Thanks

Curious if any of you remember the ASC engineering team (me and a young captain) who went around the world giving a briefing on this ditching? We also did a video of the briefing some of you might have seen. I was told the briefing was still being shown well into the late 90s.

Hello everyone, For the past month or two we've been having an ongoing issue with pressurization on our J model. The problem typically gets recognized when flying at higher altitudes, 19-20k ft, thought recently they've stated they had erratic pressurization at all altitudes. Initially the problem was erratic pressurization throughout flight, resulting in ears popping and discomfort, when at higher altitudes they received a CAB Alt high advisory because cab alt was indicating above 10k ft. We change a part, it flys 1-2 times and the problem comes back. We've changed the outflow vlv, cabin pressure controller, vacuum reg, and servo valve, some things have been cha…

Hye guys. I really need help. I had an experienced on this issue. Mine generator disc indicator on the overhead panel not illuminate during test. Before test, my aircraft do experience generator out light and failed bearing light illuminate in flight. Pilot tried to disconnect the generator with the gearbox using generator disconnect system, however the indivator didnt illuminate and it forced pilot to shutdown #3 engine to avoid catastrophic mechanical failure. On the rectification after the flight, it found that the generator had broken with shaft do also broken. From my understanding, failed bearing light is due to mechanicle failure or maybe due to the broken of the g…

Hi Folks, I'm currently planning a new module, the fuel-management. Can anybody help me with the question why the fuel management panel of a J-model (the one with the rotary switches and digital readouts) has only one tank selector? What is that rotary switch controlling? I dont find anything about a fuel selector in the public available schemata. Regards Thomas If anybody ist interested in the current status of my sim: https://c130-sim.weebly.com/

GTC problems 1 2

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?

KC-130T buno 313 and up, Having an issue where the CARA will lose altitude intermittently while in flight. Sometimes it will happen on takeoff or descent other times it will happen while cruising. (Aircrew will sometimes associate it with nav select switching but cannot be duplicated) CARA will fluctuate under 50 feet while airborne causing GPWS to go off for low altitude sometimes resetting the breaker will return it to normal other times if terrain changes it will return to normal on its own. Have replaced pilots indicator, CARA R/T and antennas but gripe still remains. Also I have shot the cables with a TDR and they seem normal. Any insight would be greatly apprec…

Hello all, Working on a KC-130T-30 and having an issue with the #2 and #4 generators holding a load. Replaced multiple components: #4 gen contactor, one of the bus tie contactors, #2/4 GCP, #4 voltage regulator. Generators will power on and give good freqs and voltages but when switched to on will not carry essential bus or a heavy load. Occasionally we can get either to pick up a bus or remove applied loads and slowly turn items on till the gen out light illuminates and freq and volts are zero. Have verified wire continuity and voltages while gen is operating normally everything checks good. When gen is in a failed state the normal voltage at the voltage regulator …
