How many tragic accidents like this (completely avoidable) have to happen before we all start thinking like this?
It also appears the RLD exceeded the LDA (5900 ft) even with the
wet runway max braking calculation, which yields 3900 ft ALD / 0,6 + 180 (for the 1 rev inop) = 6680 ft.
So even if the aircraft was, in good condition, capable of stopping in the distance available, it appears that the (FAR/JAR) 66 % safety factor was not met. Whether the flight was under a similar Brazilian regulation requirement is for someone else to comment on.
