tinyclark Posted May 31, 2020 Share Posted May 31, 2020 I couldn't find an old TCTO that made the system inoperational. This note was in the old 130B-2-4. There is also no mention of C-130B or E having it in TO 1C-130H-2-70GS-00-1. Quote Link to comment Share on other sites More sharing options...

n1dp Posted June 2, 2020 Share Posted June 2, 2020 All the aircraft in B,E,H series had the electrical control provisions installed from the overhead panel to the nacelle, but few ever had the valves or diffusers installed in the nacelles to make this work. I suspect only the aircraft for arctic service had the complete kit installed. A note: many mods later on used the nacelle pre-heat wiring to run new items such as the chip detector TCTO on US Coast Guard Aircraft. I also think the wiring may have been repurposed for augmented oil cooling system for ground use. Disclaimer: It's been a while. Quote Link to comment Share on other sites More sharing options...
hehe Posted June 2, 2020 Share Posted June 2, 2020 (edited) To the original poster: I believe you may be backwards here. The system wasn't made in-operative, it was only made operative when needed. Was a provision that could be added for nacelle pre-heat more than a system that was in-op. This Service News agrees with what n1dp stated. https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.lockheedmartin.com/content/dam/lockheed-martin/aero/documents/sustainment/csc/service-news/sn-mag-v11-v20/V17N4.pdf&ved=2ahUKEwiDzKjB2OPpAhXOs54KHTkmA4AQFjAAegQIARAB&usg=AOvVaw2F3XVTvm4-eAs2-XJEMIhL Edited June 2, 2020 by hehe Quote Link to comment Share on other sites More sharing options...
pjvr99 Posted June 3, 2020 Share Posted June 3, 2020 ye i dont think system is de-activated. even though we dont have it on our birds, many QEC kits have the wiring and c/plug. It's a standard check for us in test cell if a new engine will not rotate when starter button is pressed to then turn on nacelle pre-heat. If it then rotates, we know the shop got the starter and pre-heat c/plugs swapped around Quote Link to comment Share on other sites More sharing options...
