The preliminary accident report is now on the NTSB website.....
Thx - Renny

Reading the description, and in light of recent incident, I can't help but ask myself if this could be another broken rudder cable? A broken rudder cable with spring mechanism at low altitude could end just like that.

Steep bank, followed by pitch up, doesn't sound to me to be yaw related.
Yaw failure would most likely result in spiral or spin response with nose going down.
Jammed roll control, followed by pulling to try to keep the nose up is as likely.
That's why we can't solve these on RAS.

Nope, not enough information, and there's been no discussion on the AC4 yahoo group. However, there have been a few recent reports of AC-5M's losing props and incurring damage as a result. Some pilots have replaced or are replacing the aluminum prop shafts/hubs with steel replacements.

Just a data point.
