Enstrom Helicopters Shutters, Files For Bankruptcy
The manufacturer delivered more than 1,300 helicopters during its 64-year history.
The company was spawned by Michigan mining engineer Rudy Enstrom, who built prototypes in his garage in the 1940s and 1950s. It was formally incorporated in 1959 and its first production helicopter, the F28, was certified in 1965, beating out the iconic Ford Mustang automobile for Michigan Product of the Year.
An additional piston-engine model, the 280 Shark, was introduced in the 1970s, the decade when production peaked at 100 aircraft per year from the company’s plant in Menominee. Enstrom went on to develop a single-engine turbine model, the 480, in the 1990s. The company has had multiple ownerships over the years, including Purex Corp., celebrity attorney F. Lee Bailey, and inventor Dean Kamen. Current-production models included the F28F and 280FX turbocharged piston engine models and the turbine 480B-G.
Enstrom’s attempts to bring several other models to market, including the four-place 280L and the two-seat TH180, never progressed beyond the flight-test stage, and in recent years deliveries of in-production models have lagged. Through the first nine months of 2021, Enstrom delivered just two helicopters, according to data from the General Aviation Manufacturers Association (GAMA); for all of 2020, it delivered five.
