Goodrich's Sensors and Integrated Systems business in Vergennes, VT marked the delivery of its 2,000th helicopter health and usage management system (HUMS) in March attended by employees and U.S. Senator Patrick Leahy (D-VT). The firm has won $100 million in contracts to develop and deploy the HUMS systems for a number of helicopter platforms for the U.S. Army and Marine Corps. Goodrich Sensors and Integrated Systems Vice President Gary Loftus said HUMS finds problems while helicopters are either on the ground or in time to get the choppers to the ground safely. Goodrich's Health and Usage Management Systems (HUMS) give mechanics feedback on a helicopter's engine performance, structural performance and rotor performance - allowing a helicopter to be serviced before major system failures. Before the use of HUMS units, helicopters were routinely taken out of service for unnecessary preventative maintenance. The units are onboard a variety of military and commercial helicopters including the US Army's UH-60 Black Hawk and CH-47 Chinook, the US Marine Corps' CH-53E Super Stallion, and Sikorsky's commercial S-76D and S-92 aircraft.
