In the lighter end of GA there are plenty of aircraft which have gone from having initially poor safety records to having some fo the best in the fleet.

The Mitsubishi MU2 is a good example, it had some interesting control quirks due to having a tiny wing for its weight. After a number of reviews a training package was designed which almost completely solved its safety problems.

The Cirrus SR22 was also in a similar category, despite having a whole-frame parachute. Their problems were solved by insurance companies demanding more training and their owners group pushing the mantra "if in doubt, pull the chute".

I'm sure there are better examples from the commercial air transport end of the scale but I knew those from the top of my head.
