[5][4] Surack Enterprises purchased the assets of the company from bankruptcy in May 2022 and production was restarted, with the first helicopter completed in January 2023.

[9] In October 1968, a controlling interest in Enstrom was bought by Purex Industries, who wanted to develop a turbine powered version, a project that was not completed until over 20 years later.

The lack of success with this venture led the piston engine variants to languish and the Purex stake was bought by F. Lee Bailey, a well-known American criminal defense attorney, in January 1971, changing to the current name.

[11] Encouraged, Bailey embarked the design of a four-place stretched version of the Shark (designated 280L Hawk), but the combination of technical problems with this development and a cooling economy drained the company's financial reserves, and Bailey sold the company in 1979.

Owners have included Victor Kiam and Dean Kamen, developer of the Segway PT people-mover.

[12] Kamen worked to improve the company's existing products and to introduce the turbine-powered 480, which was originally developed as a response to a request for bids on a military training helicopter.

In January 2013 the company was purchased by the Chongqing Helicopter Investment Corporation of the People's Republic of China.

The F-28 and 280 are powered by Lycoming piston engines similar to those found in general aviation fixed-wing aircraft.

[4][22][23][24] MidTex Aviation intended to purchase Enstrom's assets in March 2022, in a deal approved by the United States Bankruptcy Court for the Western District of Michigan as part of the Chapter 7 liquidation process.
