  1. Hi. We have a problem with the gearbox pressure of a C-130 T56-A-15 engine. The pressure is low at Flight Level 100 and up. The pressure in gearbox is OK when start engine on ground. We verified oil tank, its OK; pressurization valve in the tank, its OK; shutoff valve, its OK; verified the oil lines, they are OK; changed Gearbox pump, the problem continues in the same conditions and changed the gearbox, the problem continues in the same conditions. An important detail about this problem is that when the problem occurs, the level oil tank increase. 1,5 gallons aprox. when the gearbox pressure is 148 PSI. Can someboby help us? Thank you very much. Regards.
