And A Vacuum Powered AH
can fail with the engine running just fine. Alt. vacuum is a must in IMC, but again, this is a Turboprop. Too many fallback dials remained, (according to the story) for someone to drop from 27K to 20K, shed wings and tailfeathers, and ....... I thought the Malibu/Meridian airframe had been cured of high altitude wing shedding. As of today (to my knowledge), more airframe failure fatalies with this type than panel loss induced over-stress. High aspect wing, long moment/arm, G-sensitive. I think more to follow. And what was that "obviously not pilot error" crack?
