Twin turboprop, high wing loading, spoilers on top of wings instead of ailerons. As a result of the spoilers it handles differently at slow speeds and it cannot carry much ice because of spoiler cannot activate with ice on top of wing.
Mitsubishi Industries in Japan made it.
Has killed a lot of folks, both experienced and inexperienced pilots both.
I flew the F-14A, with P&W TF30 “widow makers” and spoilers & differential tail for roll. Am all too familiar with tricky-to-fly aircraft. The MU-2 seems a particular make & model to avoid!
