About Us

It’s been 31 years of keeping customers in the air and the commitment continues! In 1989, husband &wife team, Allan & Cheryl Denesowych incorporated Yorkton Aircraft Service, after purchasing the maintenance assets of the legendary Yorkton Flying Service Ltd*. Allan being an AME and a Commercial Ag Pilot at the time “became keenly aware of the lack of support for these planes in Canada and also saw the potential for ag air in the future”. He put his ag helmet on the shelf & YAS was born. Specializing in Ag Air, YAS is the largest maintenance and parts facility in Canada. We also enjoy working with the General Aviation enthusiast. Our logo shows our name behind an aircraft, & 31 years later we can’t come to change it because we truly are behind our customers in every way.

Allan Denesowych – Director of Maintenance
