The transmission of the TH-73 helicopter is equipped with two chip detectors. These detectors are critical components for monitoring the health of the transmission system. They are designed to detect metal particles that may indicate wear or damage to transmission gears and bearings. By having two chip detectors, one can serve as a backup or provide coverage for different sections of the transmission, thereby enhancing the safety and reliability of the helicopter's operational capabilities. This dual arrangement allows for continual monitoring and can alert the flight crew to potential mechanical issues before they lead to more significant problems, promoting a proactive approach to maintenance and safety.
