Imported new in 1965 and stayed registered until 2015 when it was exported as N302SK. Still current in 2020.

Built in 1969 and on lease to a Canadian survey company. Expired as N25EC prior to 2020. The building behind dates from 1937 when TCA used it as an engine and propeller overhaul shop for radial engines and for the R-R Merlins used on the North Star. At this date it was still in use for Dowty-Rotol propellers on the Viscount and R-R Dart engine repairs. Full overhauls were done at the Rolls-Royce plant at Montréal.

The Riley Rocket is a re-manufactured early Cessna 310 (in this case a 1959 310C) with improved performance. Obvious external differences are one-piece windshield, extra side window, three-bladed propeller and cowling louvers.
