The Tutor's first flight was in 1960 and they were pulled from active service in 2000. We are now 26 years past their shelf life and spare parts are getting harder to find than hen's teeth and metal fatigue is taking it's toll on the air-frames considering the high stress maneuvers the Snowbirds perform on a regular basis. I'm as sad as the next guy that the Tutors are getting grounded BUT they have reached the end of the line. It's not like this hasn't happened in the past either. The Red Arrows had to give up their beloved Folland Gnats and switch to the BaE Hawks instead.
I hope the Snowbirds can continue with different aircraft. The Canadian Forces have lots of Hawks they can switch to or maybe change from jets to turbo-props and make a team out of their CT-156 Harvard II (T-6 Texan II) aircraft. Better yet, use some of the 19 brand new and incoming Pilatus CT-157 Siskin II (PC-21) aircraft to showcase the new type to the Canadian public seeing as it's the public who paid for them with their taxes!
I think it's one sharp looking aircraft in yellow and black!
