The company, Soloy Aviation Solutions, is located in Olympia, Washington USA, 60 miles south of Seattle and was incorporated in 1969.

Initially, the Company pursued converting piston powered helicopters, manufactured by Hiller Corporation, into turbine powered aircraft. It required over 8 years to develop this conversion and received the Supplemental Type Certificate (STC) approval by the Federal Aviation Administration (FAA) in April 1975.

The Company engineered, manufactured, certified, and installed these turbine conversions into over 170 piston powered Hiller helicopters. Most of the conversions took place in the years 1975 – 1985 and many are still in operation today.

Later in the 1970’s, the Company duplicated its earlier successes with the Hiller helicopter by applying the same conversion concept to the Bell 47 helicopter. Over 140 of these units were installed by operators and continue to support helicopter operations today. Due to market changes Soloy Corporation sold these Supplemental Type Certificates and no longer own these conversion products. Shown above is the last turbine converted Bell 47 produced by Soloy Corporation.

In the 1980’s, the Company developed a capability for converting light piston powered fixed wing aircraft to turbine engine configuration. These powerplant conversions have been installed in many Cessna 206/207 fixed wing aircraft to date. The conversion utilizes the unique Soloy Turbine Pac, designed by Soloy Aviation Solutions and approved by Federal Aviation Administration. These aircraft are available in a fixed wheeled configuration as well as an amphibious float version pictured below. Operators of the aircraft include the United States Drug Enforcement (DEA) and Royal Canadian Mounted Police (RCMP). A fleet of four aircraft is also operating for the Ministry of Public Security Air Section in Costa Rica. These aircraft are operating in a law enforcement roll where reliability and low noise levels are desired.

Other areas where the Soloy Cessna 206/207 aircraft found acceptance was within the strict noise sensitive operational environment of Europe. The parachuting clubs and training organizations of Europe have turned to this powerful and quietly operating aircraft in order to meet their current noise restrictions. There are over 30 Soloy Cessna 206/207 operating in Europe today.

Soloy Aviation Solutions also offers an American made powerplant alternative to the French manufactured Turbomeca engine installed in the Eurocopters AS350 helicopter. Many of these aircraft operate within the air tour industry in places like Alaska, Hawaii and Las Vegas. Pictured below is one of these recently converted aircraft operating in Hawaii.
