Built in 1961 and arriving for Air Spray in Red Deer in May 2010, from the Zantop heritage at Willow Run. Pacific Southwest and others flew passengers with this frame before it became a freighter by the end of 1968. As such, it lost the forward cargo door while in flight on a military charter in 1980, but survived. Undergoing a complete overhaul here in preparation to being an airtanker. The temporarily applied Canadian regi had been stripped stripped off with N290F reappering, ahead of a fresh paint job later on.

Former Zantop N290F being converted into a firebomber in Air Spray's hangar at Red Deer. In service with Air Spray as tanker #492.
