Lots of reasons for this accident and no single reason is the ONLY reason. the commonality amongst most aviation accidents is a chain of events or decisions which lead to the accident. In the end this was a pilot error accident, end of story. That is NOT a slam on the pilots. Most accidents are, and accidents happen to high time experienced pilots as well as lower time pilots. Should there be better time and duty limits for passenger operations..probably. Should some companies tighten up their training and recurrent standards...probably. Would higher compensation not allowed this accident to happen.. probably not... lots of well paid pilots commute. Hell years ago the AA crew room in MIA had this large wonderful lazy boys that LOTS of pilots AA and AE alike slept in all night. Would adherence to the sterile cockpit rule have saved this crew... I dont think so. In the best of circumstances ...well rested..well paid...well trained... pilots make errors.... what we can do to at least acknowledge that is to learn from the chain of errors and hope we are never in that situation.

You will never get the accident rate to 0. Its just not possible... airplanes are mechanical and sometime break... and pilots are human and sometimes even against all logic do things they shouldnt.
