The Enstrom F-28 and 280 are a family of small, light piston-engined helicopters produced by the Enstrom Helicopter Corporation.

Design and development

Since delivering their first helicopter shortly after Federal Aviation Administration type certification of the F-28 model in April 1965, Enstrom helicopter has produced (as of 2007) approx 1,200 aircraft.

The company produces three models, the F-28, the more aerodynamic 280 and the turbine-engined 480, each with their own variants. The F-28 and 280 both use Lycoming piston engines virtually identical to those found in general aviation fixed-wing aircraft.

The 280 was a huge design success, with a Boston-based design firm concluding a brief to make the F28 more commercially appealing. This resulted in the 280 later being named by Fortune (magazine) as one of the 25 best factory-made products in the United States.
