But getting into weather is not in and of itself enough to cause an
accident. You also need to make bad decisions and/or mishandle the
airplane. The higher the workload, the more likely you are to do that,
all else being equal.

The workload of flying a Mooney is higher than the workload of flying
an Arrow. It's not as forgiving. Thus I would expect that the same
pilots flying the same airplane in the same conditions would
nonetheless have more accidents in a Mooney.
