What is the maximum capacity for the MGB?

The maximum capacity for the MGB, or Main Gearbox, is 7.5 gallons. This figure is essential for proper maintenance and operation of the aircraft, as it ensures that the gearbox is adequately lubricated and functioning efficiently. Keeping the gearbox filled to its maximum capacity can help prevent issues such as overheating and wear of internal components. In this context, knowing the correct capacity helps ensure that aircraft maintenance routines are adhered to, which is vital for safety and operational readiness. Therefore, understanding the importance of this capacity reinforces the critical nature of maintaining proper fluid levels in aircraft components.
