One must ask how did this type get certified with such poor stall characteristics?
Squealing Pig,
Once you get beyond simple FAR 23 (or equivalent) singles, the certification requirements become quite different --- and stalling an aircraft becomes a Test Pilot only exercise, with test additions such as a anti-spin chute.
There are a few aircraft around, including the Metro, that can develop an unrecoverable deep stall.
Tootle pip!!
