From what I understand, with the introduction of the new training requirements for the MU2, it now has one of the best safety records.

 

Amen brother

 

Those numbers are high..but those numbers don't tell all of the story. The MU-2 had a high accident rate early in its life because of a number of factors..and arguably none of them the aircrafts's fault.
1.It's relatively low cost Allowed pilot/owners to jump directly from a simple single engine piston to a multi engine turbine that can do 300knots...and that was sometimes too big a jump to make, and some pilots got over their head in a hurry.
2. The aircraft uses spoilers instead of ailerons, making rudder use of utmost importance during an engine out, and NOT trying to level the wings initially (which increased the drag with the spoiler coming out).
3. The FAA instituted mandatory training, which dramatically dropped the accident rate for the last 10 years (I believe there has only been 1 fatal in that time).

Thanks wishing me well!
