I haven't seen let alone flown an A-model for over 10 years. I guess Canada still has a few about because it's cold there for most of the year. There's probably not enough remaining to make it worthwhile to STC a C40 installation, as most A's are now either crashed or turned into A+/A++'s.
I wonder how easy they are to maintain now, parts wise. It was hard enough getting parts for them whilst they were a current production model, let alone 12 (?) years after the last one rolled off the production line.
