Development

The Atol was designed by Markku Koivurova and produced by Martekno Ky and later Atol Avion Ltd. The development of Atol began in the 1970s, inspired by the American Osprey II. The first versions of the design used the Ken Rand KR structure. Atol’s predecessors were larger and their structure recalled the traditional structure of a wooden aircraft.[2]

The first water taxi tests of the new LSA version, the Atol 650, were commenced in December 2014 on the Kemijoki River, Finland, on the Arctic Circle.[3] This new version first flew on 9 April 2015.[4]

The 650 model will be built in Maine, United States, with European deliveries late in 2018 and US deliveries starting in 2019.[5]

On 3 July 2018, the 650 LSA prototype, OH-XNA crashed and burnt, near Rovaniemi.[6]
