About 95% of all the other incidents were down to pilot error
So it the case with other aircraft types.
I suggest you grasp a simple fact - we are comparing Tu-154 numbers with those of other aircraft types not analyzing a cause of every single accident. Such comparison does make sense because it is done routinely in aircraft accident statistics. if you want you can sift through every single accident for Tu-154 and do the same for 737 and eliminate every single one where pilot error was involved but nobody does it - makes no sense because it is going o be a wash and you end up as if you were comparing raw numbers without all this work.
