superbigbig Posted September 27, 2023 Share Posted September 27, 2023 (edited) Does anyone know the use of this device in C-130H? I asked a senior before that this is the position where the fuselage is pressurized when the aircraft leaves the original factory. Is this correct?

tinyclark Posted September 29, 2023 Share Posted September 29, 2023 It is named the Pressure test fitting in the TO and I can't find any real info on using it. The old 1C-130B-2-10 shows the fitting, but the book is not specific about hooking it up. This was back in the day when knowledge was handed down. It says to use an air cart though. "d. Start the MA-1A and pressurize the bleed air manifold." Suffice it to say, it was probably put there for manufacturing purposes to check the aircraft before any power was put on it to run the GTC. 1 Quote Link to comment Share on other sites More sharing options...
superbigbig Posted September 30, 2023 Author Share Posted September 30, 2023 Thank you for your reply. I also found it on our 1C-130H-2-10 PAGE3-3, but there is still no way to use it. I heard our senior maintenance staff said that it does not use any engine or APU. In this case, use a cabin pressure truck to test the fuselage pressure. 1 Quote Link to comment Share on other sites More sharing options...
Steve1300 Posted December 6, 2023 Share Posted December 6, 2023 If you do a search of the original build of the C-130, you'll find pictures of the original fuselage being submerged in a large pool and it was pressurized using that fitting to check for leaks and the pressure of final damage. The fitting was never taken out of the engineering drawings, so it is still there today. 1 Quote Link to comment Share on other sites More sharing options...

Its a port for pressurize the ac on ground by ground tester. We still use it in C-130B. Quote Link to comment Share on other sites More sharing options...
