What will happen if the intermediate gearbox fails during flight?

• A. Improved performance
• B. Loss of rotor efficiency
• C. Enhanced fuel efficiency
• D. Increased altitude capability

Answer: (B)

If the intermediate gearbox fails during flight, it will primarily result in a loss of rotor efficiency. The intermediate gearbox serves a crucial function in the transmission system of a helicopter or rotorcraft, as it transfers power from the engine to the rotor system. If this component malfunctions, it can disrupt the flow of power necessary for the rotor blades to operate effectively. A loss of rotor efficiency can manifest as a decrease in lift capability and control, making it difficult for the pilot to maintain stable flight. This failure can lead to increased vibrations and potential total loss of rotor function, severely compromising the aircraft's ability to fly safely. In contrast, factors like improved performance, enhanced fuel efficiency, or increased altitude capability do not logically follow from a gearbox failure. Such outcomes would require a fully operational system; hence, they are not applicable in this scenario. The consequences of a gearbox failure are typically negative, emphasizing the importance of this component's integrity during flight operations.
