Looks like three people didn't do their jobs correctly. First the mechanic with the extra part and didn't follow the tech data (obvious). The person that signed off the work without looking at it (obvious) and the QA person that failed to find a major error in the assembly, that is if they even looked. At any one of these given points this could have been avoided. As it is, failure to follow proper procedures resulted in the total loss of an aircraft and fortunately no lives lost.
China's maintenance practices are not the best in the world and this case is totally unacceptable in the light of those practices.

That accident happened because the mechanic didn't double check the windscreen screws against the parts list. He eyeballed some screws that were about 1/8th of an inch too short, and thought they matched up.
