Cessna U206G ZK-TCA was listed with Oceania Aviation, Ardmore, on
17 February 2016 and is seen here departing Ardmore 14 April 2016.
In November 1977 the Japanese Maritime Safety Agency registered the Stationair 6 JA3790 with the operation being renamed Japan Coast Guard somewhere along the line. It was cancelled from the Japanese register on 25 August 2015 so it took a while before it inherited a new identity.
Currently there are 49 Cessna 206 of all variants on the ZK register plus YJ-RIR parked at Ardmoer.
