Mazurb Posted August 20, 2015 Share Posted August 20, 2015 We have an H1 74-1664 that came from Little Rock that has two 10 Amp DC circuit breakers labeled VHF FM. The wiring diagram 2RF4.00 only shows one. The second breaker was collared and we are trying to find out why so we can properly annotate our forms for an upcoming inspection. All other aircraft have only one CB. Does anyone know what the second one was for? Was there ever a third VHF, a TCTO, or perhaps a test installation that never came to fruition?

n1dp Posted August 20, 2015 Share Posted August 20, 2015 What are the wire numbers that it is feeding? Quote Link to comment Share on other sites More sharing options...
tinyclark Posted August 22, 2015 Share Posted August 22, 2015 What n1dp said. could be the old FM radio in the wing. You need to check wire numbers. There could have been an VHF FM radio installed. Please let us know.. Quote Link to comment Share on other sites More sharing options...
noizeedave Posted August 25, 2015 Share Posted August 25, 2015 If the aircraft was ever a fire fighting aircraft, it might be for the old MAFFS radio, but im not familiar with the Tail #....MAFFS radios are FM radios and had there own control panel that would be installed during MAFFS OPS..... If the aircraft was ever with Wyoming, Colorado Springs or North Carolina, might be it. Im a California guy and we never owned a 74 model. Just a thought....

Mazurb Posted August 27, 2015 Author Share Posted August 27, 2015 Unfortunately the wire numbers are illegible if any. This plane is also one that is the only one with the Digital CVR and the first one to have the 406 ELT. We suspect it was probably a test bed of some sorts.N1DP, 73.

tinyclark Posted August 28, 2015 Share Posted August 28, 2015 We had that aircraft in Alaska at one time. I know on the pilot's lower circuit breaker panel there were two, but marked VHF XMTR and RCVR. The regular VHF circuit breakers were on the co-pilot's upper panel from what I remember, but it has been a long time. I don't know if that aircraft was sent to Yokota before Little Rock or not, but it was one of our regular H models. Quote Link to comment Share on other sites More sharing options...

tinyclark Posted August 31, 2015 Share Posted August 31, 2015 (edited) The date's on my iPhone calendar, I'm safe. Mazurb, if it was a test installation, the wires should be orange. You may have to cut some string or tiestraps back to identify the wire number. Since the breaker is strapped, why not remove the breaker, then cap off the wire?

hehe Posted September 2, 2015 Share Posted September 2, 2015 Was this bird ever a senior scout airframe?Something like 60 c-130e/h's flew senior scout at one time so its very possible this one did. Im only familiar with the ones i saw with senior scout but if it was ever at dyess its very possible. Quote Link to comment Share on other sites More sharing options...
tinyclark Posted September 3, 2015 Share Posted September 3, 2015 (edited) It was at Dyess before Elmendorf. I think someone would have questioned me on the strapped circuit breaker at the 'Dorf'. I think those Dyess birds had APQ122V5 RADAR in them as well. They ended up putting the APN59 back in them.
