The T53 family of engines has logged more than 50 years of service and more than 62 million flight hours on some of the world’s most iconic helicopters including the Bell UH-1H Huey, Huey II and AH-1H Cobra, as well as the commercially certified Kaman K-Max, Bell 204 and 205B helicopters.
Originally developed by our legacy company Lycoming, the T53 design team was headed by Anselm Franz, designer of the famous WWII Junkers Jumo 004, the world’s first turbojet engine.
Today, the legacy of the T53 remains intact. A properly maintained, 30-year-old T53 still meets today’s rigorous reliability standards. If fact time between overhauls (TBO) has been increased to 5,000 hours.
