Hello, I am a maintaner for a C-130H that lives in a museum, i want to make sure she gets well maintained and so i am learning as much as i can about the C-130. Apart from that, said museum also has a simulator: I noticed during a few startups that the SEC fuel pump press light goes out before the start valve open light goes out. However during startup callouts; FE calls: Indicator, fuel flow, lightoff, Oil Pressures, hydraulics, Parralel,(starter), Valve, Series Is this normal behavior? I know start valve light can take up to 15 seconds to go out but should the calls then be Series, Valve? Note: i might have forgotten to tur…

RNZAF C130H keeps shearing towbar pins. We found that the NWS steering indicator feed back drive chain in upper indicator dial had stiff links and stuck during travel and we thought that this was not allowing steering valve teeter totter arm to cycle whilst towing and causing a lock thus shearing towbar pins. We lubed chain and it appeared to fix problem but now the shearing has reoccured. Has anyone had this problem. We have not changed valve. It naturally does not do it with arm disconnected. NWS rigging i.e cable tension correct and even and teeter totter arm correct. The NWS operates as required when on skid plates. Cheers Kal

Hello, Wondering if anyone has seen a training manual set for c-130j. I have c-130a, c-130e and multiple c-130h training manual sets that have around 9 volumes per set of different systems. I have never seen one of these sets for c-130j but maybe foreign operators were given some of these from lockheed back in the day. If you have seen one or know someone with one, please contact me.

There is no fuel flow on all engines despite changing the fuel flow power supply unit, the fuel flow still doesn't indicate in the flight deck. All fuel indicators are servicable. The aircraft model is a C-130H

Hello everyone, Do you think we should turn the NESA heat OFF after having a cracked window in a C130J ? the -1 docs doesn't say any thing about this subject! all it says "If a window is found to be arcing, the NESA system should be turned off. The intense local heating at the spot where the arcing occurs can cause the window to delaminate and crack. The longer arcing occurs, the more opportunity there is for damage to occur." Thanks!!
