If right TAGB oil pressure is lost, what will fail within minutes?

The loss of oil pressure in the right TAGB (Turbine Accessory Gearbox) is critical because it directly affects the associated components that rely on that oil pressure for lubrication and cooling. In this specific case, with the right TAGB oil pressure lost, the No. 2 CFG (Compact Fuel Gearbox) is the component that will fail within minutes.

This failure occurs because the No. 2 CFG is dependent on the oil pressure provided by the right TAGB for its proper functioning. Without this oil pressure, the gearboxes and other components cannot be lubricated effectively, leading to overheating and rapid wear or failure. The No. 1 CFG and the PRGB (Power Reduction Gearbox) are not immediately affected by the loss of oil pressure in the right TAGB, as they have separate lubrication systems and operate independently to some extent. The main rotor system is also not directly at risk in the immediate term from the loss of oil pressure in the right TAGB since it primarily relies on different systems for its operation.

Thus, the understanding of gearboxes and their reliance on specific oil supplies is essential in determining the impact of losing oil pressure in the TAGB. In emergency situations, maintaining awareness of which systems are critically
