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 there has been an issue regarding the material of intermediate Control Rod on Allison T56 A15 engine on C130 E models. Can someone guide me about the material from which these rods are made (is it non ferrous or stainless steel?) and what NDI Inspection is to be carried out on these rods (FPI or MPI)?

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

Hey Herk friend. One of my Eng/ prop rpm increases upto 105% during opening pwr with freq and then comes to 100% after 6-7 sec with freq 400 Hz. When rpm increases to 105%, then TIT remain 750-800(-7B). After reaching 100% rpm, TIT starts rising. Again while retarding throotles back to Flt Idle, rpm comes to 95-94%( on grd) and 96-97% in flt, then increases slowly with freq. That is in Normal, mechgov and synchro mode.
