Osterman Helicopter i Östersund was a privately owned company with main bases at Säve Airport in Gothenburg and Göviken Heliport in Östersund. It offered a wide range of services, including sling-load operations, air taxi, measurement flights and various aerial works. The company operated all over northern Europe.

Osterman Helicopter went bankrupt in September 2012, and the trademark "Osterman Helicopter" has been acquired by Laroy Flyg (2).

HistoryOsterman Helicopter derived from the old company Ostermans Aero AB's flight department in Gothenburg. Ostermans Aero was the world's first helicopter company outside the USA, and it was a true pioneer in Sweden. When Osterman decided to close its activities in Gothenburg the region a set of former employees were granted the Osterman name and subsequently established the new company Osterman Helicopter AB in 1981.

The company acquired the agricultural aviation company Laroy Flyg (1) in 1988, which incorporated operations like liming and fertilizing into Osterman's line of business.

Osterman Helicopter inherited Ostermans Aero's activities in Stockholm in 1991 as Ostermans Aero decided to focus fully in its maintenance and broker activities.

In 1993 Osterman Helicopter initiated an ambulance helicopter activity in Uppsala in cooperation with the Uppsala University Hospital. Osterman lost the contract in 1996, but won a new ambulance contract in Stockholm.

Osterman Helicopter purchased the Borlänge and Östersund based company Heliflyg AB in June 2000, which merged the two company fleets and bases together and added the Östersund based EMS helicopter to Osterman's activity.

Norwegian Air Shuttle AS (NAS) and its subsidiary Lufttransport AS acquired Osterman Heli's ambulance helicopter activities in Östersund and Stockholm in September of 2001.

In January 2002 Norwegian Helicopter Transportation Group (HTG) acquired Osterman Helicopter AB. The company was merged together with the Swedish shuttle and training company HelikopterService Euro Air, with Osterman in the leading position.

Osterman Helicopter entered partnership with Jämtlands Aero (2) in February 2004, which made Osterman responsible for the partner's operational and technical management. Jämtlands Aero (2) remained as a vending company for a period of time.

Osterman Helicopter was purchased from HTG by the company Skyline Helikopter in 2005, and their fleets were merged into the new version of Osterman Helicopter.

In late-2009 the Norwegian company Nordenfjeldske Luftfart AS purchased Osterman Helicopter, but the new owner gave up the ownership just short of a year later. Nordenfjeldske Luftfart AS sold it back to the previous owner.

The company dry-leased several helicopters (Jet Rangers and a Bell 212) to the Swedish Armed Forces Helicopter Wing for recurrency purposes for a few years. The helicopters were needed to maintain the flying skills among the flight crews as the deliveries of new military helicopters were running slow.

Osterman Helicopter went through a total renewal process in the autumn of 2011. The company was gradually transitioned into Osterman Helicopter i Östersund AB and the new organization got its own air operator certificate in November. The old company, Osterman Helicopter i Göteborg AB, went bankrupt in December 2011.

The new company, Osterman Helicopter i Östersund AB, was active for roughly 10 months before it went bankrupt on 4 September 2012. The business was closed, but the legendary company Osterman Helicopter had left an historic imprint in the Swedish helicopter industry. Its name will forever be associated with professional helicopter services - where no task is too big or no load is too heavy.

Following the bankruptcy, the trademark Osterman Helicopter was acquired by Laroy Flyg (2) in the autumn of 2012.
