Lears are notorious for having no margin for error with regard to how fast you need to react to pp failure.... I'd bet you a week of lunches that's all it was... slow reaction time that led to a stall, then poor proficiency with regard to single engine emergency procedures on the part of the crew. Only thing they could do was ride it into the smoking hole.
Sorry folks this airframe is a magnificent airplane..... until it isn't. Then, it's a snake.
