What is the maximum allowable transmission oil temperature?

• A. 100 C
• B. 110 C
• C. 115 C
• D. 120 C

Answer: (C)

The maximum allowable transmission oil temperature for the TH-73A is indeed set at 115°C. This temperature limit is established to ensure the safe and efficient operation of the helicopter's transmission system. Operating above this prescribed threshold can lead to excessive wear and potential failure of transmission components, as higher temperatures can degrade the oil's ability to lubricate effectively. It is critical for pilots and maintainers to monitor transmission oil temperatures closely during flight operations. By adhering to the established limits, the risk of overheating and the associated detrimental effects on the helicopter's performance and reliability can be minimized. This operational parameter is a key aspect of maintaining the aircraft within safe operating limits, contributing to overall flight safety and mission success.
