17 aircraft on the Canadian register give CST7 as their base, and the middle one was built in 2006. The oldest dates from 1965, the newest from 2025.
1 of them holds a Special Certificate of Airworthiness for owner maintenance. That is worth knowing before you buy one: it is a one-way door, and an aircraft cannot readily go back to a standard certificate. What the certificate types mean.
