Reading the article it looks as if there were too many cooks in the kitchen. Perhaps the actual licensed, qualified pilot for the aircraft could have handled the problem(s) himself and kept everyone alive.
Sounds like the pilot in charge was oblivious and couldn't handle anything. Possible thrust reverser issue? Ignore. Engine temperature mis-match? Ignore. Electrical issue? Apparently addressed, which could mean something wasn't done right on the pre-flight checklist.
There were likely mechanical issues with the plane, but the root cause appears, from this story, to have been pilot error.

Reads to me like the pilot was ignoring indications and concerned passengers were pointing that out.
The accident was--at least in part--the consequences of hubris, IMHO.
Biffle, himself holding a license to fly the Cessna, was also not rated to be a co-pilot. However, Biffle was in the back seat.
