The R.J. Enstrom Corporation, named after its initiator Rudy Enstrom, was officially organised in 1959 in Menominee, Michigan. Their first more thoroughly engineered helicopter design was the F-28. The two-seat prototype of the F-28 was flown first on 12 November 1960, followed by the first of two three-seat production prototypes on 26 May 1962. Initial FAA certification was achieved for the F-28 model on 15 April 1965. The Enstrom F-28 was built in limited quantities. A more powerful version, the F-28A, was certified on 28 May 1968. This helicopter entered full rate production, and over 300 helicopters of this model were manufactured. After ownership of the company changed in January 1971, the company name was changed into Enstrom Helicopter Corporation. A collaboration between a Boston industrial design firm and the Enstrom engineering team yielded a new aerodynamically styled airframe, the 280 Shark. This new model was certified in September 1974 and immediately put into production. Over the years a number of models were developed and produced based on the body style of the 280. After preliminary market and design studies Enstrom initiated the development of a larger, turbine-powered helicopter in 1988. Two versions were to be developed: a three-seat military trainer, the TH-28, and a five-seat, commercial helicopter, the 480. The turbine-powered 280FX, a modified piston-powered model in which an Allison 250-C20 turbine engine with the Enstrom drive train and rotor system was integrated, flew first in December 1988. The maiden flight of the 480 with wider cabin was on 7 October 1989, and the TH-28 was flown first in 1990. A production representative helicopter made its maiden flight on 21 December 1991. The TH-28 was granted FAA certification to C.A.R. Part 6 standards in September 1992. Initial FAA certification for the 480 was received on 7 June 1993; in December 1994, the approval was extended to FAR 27 standards. Development of the more capable 480B variant powered by the Rolls Royce/ Allison 250-C20W turbine powerplant had begun in the spring of 1999, and FAA certification of the new model was obtained on 9 February 2001.

On 15 March 1996, the Enstrom 480 c/n 5015 was flown first. On 14 February 1996, the by an Allison 250-C20-W turbo-shaft engine powered helicopter was registered G-OGHH in the UK with Southern Air Ltd., Shoreham Airport. On 28 June 1996, registered ownership of the G-OGHH, was changed to G.H. Harding, Whitchurch. On 15 April 1999, registered ownership of the G-OGHH changed to Silver Linning Finance SA, Luxembourg. On 11 June 2004, registration, G-OGHH was cancelled as exported to the USA. On 4 August 2004, the 1996-built Enstrom 480 was registered N480SF in the USA with Schuybroek Aviation Inc., Dover (DE), and was operated out of Antwerp Airport in Belgium. On 2 April 2010, registration PH-HPA was reserved by A.M. Prince, Zonnemaire, as operator, and B.C. Snijders, Raamsdonksveer, as owner, for The Enstrom. On 22 June 2010, registration N480SF was cancelled as exported to the Netherlands. On 24 August 2010, the Enstrom 480 was registered PH-PHA with Prince Helicopters, Zonnemaire, as operator, and Airworks Aviation Solutions BV, Raamsdonkveer, as owner. On 29 June 2012, registered ownership of Enstrom 480 the PH-PHA changed to R.V. van der Linden, Hoek van Holland. On 18 August 2014, the Prince Helicopters' Enstrom 480 Turbine PH-PHA was seen at the Heli Holland heliport near Emmen.
