Delivered new in 1990 to Frontier Air Service as C-GFAF. Later returned to Beech Aircraft then re-imported as above in December 1998 on lease to Ministic. A further lease to Northern Thunderbird Air took place in 2001 then it was exported as N324SA in 2017 and current with Southern Air Charter in 2023.

Delivered new in 1996. It reads 'Property of Garden Hill First Nation' on the lower cowling which may mean they came up with the cash. Sold to Wasaya Airways in 2002 after Ministic Air closed down and current in 2023. The Kistigan inscription is in reference to a popular tourist fishing lake at the time and likely a frequent destination for the aircraft.

Built in 1970 and here just imported. Current in 2022 with Buffalo Airways, its fourth northern operator. Eclipsed by the Super King Air, these became popular with northern operators due to their low hull value. Apart from the acquisition cost, this made them cheap to insure, an important factor when considering their high-risk theatre of operations.

Built as a E18S in 1956, this Beech 18 was converted to a Super Turbo Tradewind in 1966. Ministic Air bought it from Union Flights (N25SM) in January 1991. Unfortunately the aircraft undershot an approach in poor weather and impacted a frozen lake at Little Grand Rapids, MB on May 2, 1992. Wreckage was recovered from the lake by K & K Aircraft and taken to Bridgewater, VA as a source of parts.
