ENABLING FLIGHT TOGETHER SINCE 1982
Joen Service was founded by Pertti Lahti in 1982.
Pertti had begun his career in aviation as a Mechanic in the 1970’s. Back then, there was a shortage of mechanics. Pertti very quickly found himself in high demand and ended up moving from Helsinki Malmi Airport to Joensuu to run an aircraft maintenance company.
North Karelia provided firm roots for Joen Service. Customers at the start included Finnaviation, private aircraft owners and local aviation clubs.
To secure the company’s future during the recession in Finland in the 1990’s, Pertti expanded services to include helicopters. His keen interest in aviation and extensive experience in aircraft maintenance was also passed onto his son, Mikko Lahti, whose first summer job as a teenager was Assistant Mechanic at Joen Service. That experience eventually lead Mikko to become an Aircraft Mechanic for Finnair.
Joen Service became Finnair’s local partner at Joensuu Airport in 1997. The company provided the Finnish national airline technical services until 2005 and ground handling services from 2022.
