Not to my knowledge. Every MEL applied to the aircraft was fixed, and even then it was nothing major, the aircraft could continue to operate safely with a degree of redundancy still built in.
Rex on the other hand…of course I can only speak for the Saab…but issues would pile up and there would be MEL stickers everywhere. Things would continue to get deferred and there was always the problem with the de ice boots on the tail plane in winter (every winter).
I’ll leave it with this, every time I walk onto a VA aircraft, the maintenance sheet is fairly clean. That’s not to say that things won’t ever happen. Planes are machines.
Just like cars and even computers. Sometimes for some unknown reason, things just decide to take a holiday themselves.
Take of that info, what you will. But of course VA got rid of the older ones. Makes business sense right? They now have a much younger fleet on average and better for insurance.
