George, #333, as per the issue above #332, the QAR view in isolation might at best only provide a small improvement, but never a guarantee.
Again from James Reason ' even the very best people make the worst mistakes ', which has to be considered in context - the actual situations; accidents generally have several contributing factors, which come together at a particular time. '… the chance and largely unforeseeable concatenation of many different causal factors, none of them sufficient or even especially remarkable by themselves, but each necessary to bring about the outcome.'
The need of defence in depth.
Operators should reduce landing distance available by the amount of an unsuitable overrun area.
Airports should inspect runways more frequently in monsoon conditions; have time delay landing restrictions for poorly drained surfaces, check and publish rubber contamination (slippery when wet).
National authorities should require grooved runways, for those airfields without then reduce landing distance available to compensate for reduced braking / drainage.
Governments should allocate funding for improvements, act to instigate the above.
