The accident report does not give much info on the pilot, how many hours he had and how many in type, so it is hard to judge his experience level. but it does say he already made two landings that day. No weather data given, so I don't see where you guys are getting a tailwind on base as a factor.

Would an AOA indicator have helped. Well, if he had a clogged pitot or some airspeed indicator malfunction, and the AOA came from a separate source, it could have helped, but only if he looked at it.
I wonder if he really did 2 stalls and recoveries at low altitude on the previous approaches or if he might have been hitting wake turbulence from other planes as it was a fly in.

It seems strange that we don't know anything about radio talk with the advisory tower while he is doing the 3 approaches.
