Seems to be a common issue with a King Air 90.
- Usually the guys flying jumpers are green time builder pilots.
-A twin doesn't have the same torque or P-Factor that a single engine.
-They try to get as high as they possibly can for the enjoyment of the jumpers. Thus at maximum altitude for weight to power to lift to drag.
- The roll to the left probably has more to do with the excessive drag, fast change in wt/bal., and an open door. And poor pilot skills allowing himself to get in this situation.
If you look on YouTube, this guy isn't this first to make this mistake. There are those who have, and those who will.
Here's another guy, could even be the same guy?
