About the Enstrom Helicopter Corporation 480B

The Enstrom 480B represents the turbine evolution of a classic American light helicopter lineage that began in the 1960s. Built by Enstrom Helicopter Corporation in Menominee, Michigan, the 480B replaced the piston-powered F-28F with a Rolls-Royce 250-C20W turboshaft engine in 1993, transforming the type into a capable single-turbine utility and training platform. The fully articulated three-blade rotor system and streamlined fuselage give the 480B excellent handling characteristics and a reputation for docile flight manners, making it popular with flight schools and private operators who value predictability over raw performance.

With a maximum gross weight of 3,200 pounds and a never-exceed speed of 120 knots, the 480B occupies the light end of the turbine helicopter market alongside types like the Robinson R66 and Schweizer 333. Its enclosed cabin seats four in relative comfort, and the turbine powerplant provides better hot-and-high performance than its piston predecessors while maintaining reasonable operating costs. The type found a niche in primary and advanced helicopter training, utility patrol, and personal transport roles where a light turbine helicopter's reliability outweighs the need for heavy lifting capacity or high-speed cruise.

Production numbers remained modest throughout the 480B's run, with Enstrom building helicopters in small batches as orders arrived. The company changed hands multiple times over the decades, and production paused and restarted several times, but the 480 series remained in the catalog as a proven design with a loyal following among operators who appreciated its American engineering and straightforward maintenance. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
