Dear All, Greetings, Our C-130 “G†unit indicator read 4.0 G, I want to know if this indication is over "G" and acceptable or not and if not acceptable what type of inspection is required and which manual should be used to see the required inspection procedures. Your efforts is highly appreciated Thank you in advance

Hope you are doing fine, C-130E heavy white smoke from outlets of the both air-conditioning systems during operation at hot position while all engines are running, we try with #1,#2,#3 and #4 engines the same still heavy white smoke from outlets, when #3 engine is selected the white smoke is more than others, when using GTC bleed air only no smoke for the outlets Thank for your help

Yes my frined I agree with you, but my pilots not acceptable because when you operate one of the air conditioning systems with override position of bleed air regulator & shut off valve the bleed air pressure drops to 63 PSI Thank you

thank you my friend for your effort and help With load read 64PSI one of both air-conditioning operated My friend my country is Jordan Direct pressure gauge connected to bleed air manifold aircraft pressure of bleed air still the same we hook a hose up to the pressure test fittings on compressor diffusers the pressure still reads 70 psi Flight deck and behind the Nav's station for a broken bleed air line also checked for bleed air leak and broken line nothing found thank you

bleed air valves are regultor & shut off valve the mulafunction at overide position

bleed air leak check time is within the limits reads 10 seconds bleed air manifold gage replaced by new one

to fix it

My aircraft bleed air system manifold pressure gage, reads below 70 psig while all engines are running all engine bleed air regulator & shut off valves replaced by new ones , all pneumatic systems manifold and connections are checked ,both air conditioning checked for air leak, can any one help me about this malfunction
