Copterline

Copterline acquired Helikopteripalvelu in 1999, the oldest Finnish company in the business, and began offering services in 2000.

[7][8] On 10 August 2005, Copterline Flight 103 crashed while flying between Tallinn and Helsinki, three kilometers south of Aegna island.

[9] In August 2006, Copterline sold its last remaining S-76 and focused on charter flights resuming the route between Helsinki and Tallinn on April 9, 2008, with a new AgustaWestland AW139 helicopter.

On 19 December 2008, Copterline confirmed that it had ceased its scheduled service between Helsinki and Tallinn and was now looking at the possibility of alternative uses for its helicopters, otherwise, it will sell or lease its aircraft.

Plasma coating on the pistons of the power flight control system had flaked off and blocked the return valve, causing the aircraft to lose its maneuverability.

Copterline used four Eurocopter EC 135 helicopters for emergency and medical service operations from three different bases: Oulu, Tampere (formerly Vaasa), and Varkaus.
