On approach for landing, a C130 E Model aircraft lowers landing gears only. Flaps are already down. While Lowering the landing gears, utility pressure drops to 1375 PSI and low pressure EDP light of both Engines and low pressure light of Utility Suction Boost Pump illuminated. As soon as the Landing Gears were extended completely, system pressure came back to Normal with all conditions within limit. To what component can this occurrence be attributed? Can it be the failure of Utility System Accumulator, Suction Boost Pump or EDP? And if we were to attribute this to Accumulator, is it possible for an Accumulator to suck hydraulic pressure from pressure line to fulfill its …

Hello all, I was an RCAF Herk rigger in the late 70’s. I am trying to find a diagram or clear photo showing the location of the early blue formation lights located on top of the wing. If I recall, there were 4, 2 on each side, aft of the box spar. Flush mounted, probably about 3” in diameter with a cobalt blue lens. I am a model builder and want to light up my Herk. I remember them from when I was doing DI’s and was up top checking for cracks or damage to the surfaces. So these were CC-130E and H. This was before the slime lights. Any information would be greatly appreciated. Best regards, Jeff

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!!

An/arc-190. Had hf 1 and 2 coupler fault pop up mid flight. Would rx but no tx or tune tone. Repressurized #1 coupler and both started started working again. Didn't make sense to me why #2 would start working other than the rf interlock relays are the only thing that shares a connection (i believe). However, sys would work fine until the next day, and the same problem returns on both system. Repressurized #1 again and both starts working. Anyone seen due to hf 1 fail, to cauaes #2 to fail as well? Could this coupler be losing pressure over night? Dont have any parts so im trying to narrow it down
