Thanks to their versatility and manoeverability, helicopters are widely used in a variety of sectors. As with any aircraft, service and maintenance are vital in ensuring the safety of the crews and passengers. The world leader in rotor wing maintenance, repair and overhaul is Heli-One, which is headquartered in Vancouver, Canada. The company’s history dates back to 1956, when Helikopter Services was founded in Stavanger, Norway. Its most recent expansion was the establishment of Heli-One Poland Sp. z o.o. in Rzeszow. It provides service from nose to tail on 13 leading helicopter models.
