Our Team

I am Allan Denesowych, Co-Owner and Director of Maintenance at Yorkton Aircraft Service. I hold a commercial pilot's license as well as my AME license.

I have been working on Ag planes for over 40 years, even spent some time being a ground flagger, then an ag pilot from 1985-1989 in a Piper Pawnee and an Ag Cat. While fixing and flying I became keenly aware of the lack of support for these ag planes in Canada.  My wife encouraged me to develop an Ag Air focused maintenance and parts business so I put my ag helmet on the shelf.  I started growing my contact list and we soon became distributors for many USA based Ag air supplying companies. We also support General Aviation enthusiasts as well.  I’ve lost count of the number of apprentices I have trained but I can almost remember every aircraft I have worked on.  My maintenance rule that I pass on: now that you have fixed it, would you get in and fly it?

I work with a great team here at YAS. Many of us are pilots too, which we believe strengthens our maintenance organization perspective.  31 years ago we had a vision to be there to keep you in the air.  It remains our promise today. I invite you to check out our story,

So here I am, the co-owner of this company that made Al quit crop spraying.  No I wasn’t afraid of crop spraying being a dangerous occupation; back in 1989 it wasn’t a full time job and we just had our first baby boy.  I knew Al had an engineering mind, a hard working attitude and a mindset ready for challenges.  I was a bored government employee with a Business degree and a drive to be an entrepreneur.  So yes it was my idea but I did allow Al to be the 51% shareholder!  I'm not a pilot but I did ground school twice (yikes!) and I caved on my pilot training about 15 hours in.  I have a very, very strong respect for Pilots!

Both Allan and I are passionate about this industry, helping others and building on opportunities. We are thrilled to help our team members grow their skills and become professionals.  Allan and I have had a ton of fun together growing and developing this busines. Being led by a husband/wife team, it's natural for YAS to have a family like attitude with our employees, our customers and our suppliers.  We’ve made many great friendships over the years.  We’d love to add you to the clan.  Email me or call me and let's have a conversation!

Thanks for visiting. We look forward to meeting you.

Tanner grew up in the ag aerial application industry, literally.  He is 3-months older than Yorkton Aircraft Service Ltd! Tanner started Ground mixing at 15 yrs old and continued through high school, but left the industry after losing a bud in an Ag plane crash. He started flying pipeline patrol and that brought him back to ag flying. He has flown 8 seasons as an ag pilot, in almost every aircraft type.  His most recent 3 years were in a Thrush Turbo prop.  He has done 3 forestry tours; and in total has 3500 hours PIC time.  Tanner always considered getting involved in the family business and decided to do that in May 2020. Working on becoming YAS Director of Sales he is focused on Thrush sales, GPS sales and parts. He brings a fresh and creative spin to the business while believing strongly in the YAS brand and its promise to the industry.   A director on both the Saskatchewan and Canadian Aerial Application boards, he enjoys seeing the industry as a whole, not just from the pilot seat!  Tanner looks forward to helping you Keep in the Air.

Nathan has been at YAS for 15 years and leads our floor in experience.  He's a big guy with a BIG laugh (we are warning you)!

An upbeat guy, he stands in for the DOM as necessary and he is also a private pilot.

Kyle is one of those strong and quiet types! He has his pilots license as well.  An 11-year employee - he is our radial guy but already making great strides in the turbo world.

Juan is a newly licensed AME!.  A dedicated employee with a strong work ethic and a teasing attitude, we tease back - we call him by his Juan name.

Jon and his family moved to Yorkton in August and wasted no time in finding an acreage close to the airport. Jon brings us insight from his experience at other AMO's.  Jon is a great asset to our team!

A valuable apprentice on our team, Preston is also a private pilot (and a biker).  He has a postive attitude and learns everyday.  Dependable Preston!

Jarek started out as a summer student, and moved to a full time position upon graduating highschool.  His willingness to help doesn't go unnoticed.  He's proving his interest in all things electrical.  AMEN to that!

Kaci is Miss Friendly. She manages our marketing and social media campaigns, helping us to spread our “we’re there to keep you in the air” messages. Full of ideas and a gentle spirit, Kaci brings a special sunshine to YAS. Kaci is married to Allan and Cheryl's youngest son, Cole.

Tracking numbers, traceability, batch numbers, locations, it goes on and on in Caroline's shipping and receiving area.  Our 20 year employee is appreciated for her dedication and the organization she brings to our AMO. 

Cathy's extensive business and administration experience has been extremely valuable to Cheryl. She often comments about her work ethic coming from growing up on a farm with xix other siblings.  An avid golfer and curler too we will be relying on her to boost all of our games.

Klay is intrigued by all things mechanical and he is entering the aviation world with focused interest.  He is a vehicle buff but doesn't want that passion to become a career, he wants to keep it a hobby. Smart thinking Klay!

Meet our Hangar Man Colton.  He is a character, and a real hard working one! He does everything you ask of him, except for separating from his orange toque....
