The ST-27 was designed by the Canadian Saunders Aircraft Company as a conversion of the earlier de Havilland Heron.

Ex LN-NPI, LN-SUL, OY-ADV. Converted to ST-27 as CF-LOL in 1972. To Air Atonabee of Toronto, Ontario. Cancelled 23 January 1990. Seen in the Western Canada Aviation Museum reserve store compound.

After only two years in service the paint has come off the leading edge and forward fuselage though hard usage. In the spring on unpaved runways, the top inch or two melts first trapping water and creating muddy 'soup' which clings to the tires, as here. Last operator was City Express of Toronto and cancelled in January 1990 with remains in storage at St. Andrews/MB.

Originally flying in Scandinavia as a De Havilland Heron with Braathens SAFE registered LN-NPI. It came to Canada in 1972 becoming CF-LOL and was Saunders Aircraft's sixth ST-27 conversion. It's now resting in the Western Canadian Aviation Museum off-site storage area.
