to open the route again in August 2013, but these plans were postponed and later cancelled. The company currently provides helicopter services to the oil and energy sector on the North Sea. In March 2016, Copterline OÜ filed for bankruptcy for the second time. Incidents and accidents In spring 2004, the company had been restricted from commercial flights in bad weather conditions, due to concerns about pilot qualifications, but the restriction had since been lifted. On 10 August 2005 Flight 103, a Sikorsky S-76, crashed into the sea near Tallinn, Estonia, three to four minutes after taking off. The craft was carrying 14 people, all of whom were killed: six Finnish, four Estonian and two American passengers, and two Finnish crew members. The disaster was caused by the failure of the power steering system of the American-built helicopter. According to Estonian authorities, no distress signals of any kind were received. However, after examining the helicopter's black box it has been reported that the pilots had attempted sending one, but wasn't received because an air traffic controller in Tallinn Airport was reading back a landing permit. The black box also revealed that the pilots had remained calm and attempted a safe landing in a "by the book" fashion. The cause of the accident was the failure of the power flying control system. Plasma coating on the pistons of the power flying control system had flaked off and blocked the return valve, causing the aircraft to lose its maneuverability. It was revealed in 2007 that the failed component was inside a system that Copterline did not have the authority to service or even open. A periodic leak test that could have revealed the problem was omitted. Furthermore, the emergency floats failed to operate. The manufacturer, Sikorsky, confirmed that damages have been paid to the families of the casualties, but a court case between Copterline and Sikorsky is still pending. Fleet The Copterline fleet consists of nine helicopters and several rescue craft. Copterline uses four Eurocopter EC 135 helicopters for emergency and medical service operations from three different base: Oulu, Pete got moved from Vaasa to Tampere and Varkaus.
