Yep..understood.
I'm simply suggesting the combination of adverse environmental conditions at the time of the accident (DA and Wind-shear) are VERY LIKELY to have been 'contributing factors'... As you correctly outline, other aircraft operated 'safely' just prior to the accident.. However, the ACTUAL 'recorded' winds in the immediate time window (15 seconds to 2 mins) prior to 521 crossing the runway threshold MAY have been MORE adverse (actual direction and actual strength) than the winds experienced by preceding aircraft.. Immediately following the accident, aircraft would have been limited/re-cleared to the parallel runway, which is also likely to have been subjected to LESS ADVERSE wind/turbulence conditions.. Note that Dubai Airport accommodates some of the largest aircraft maintenance facilities in the world..located immediately adjacent to the runway touchdown zone..
