Mechanical calculations cannot be more accurate then the mathematical or phisical model you are using. You can use such model and choose such point of impact force so the damage is very minimalised. It is not problem for any engeneer. It is not physical question but a question of responsibility, true and independence of their minds.
High lift device on leading edge /slots/ was surely considerable destroyed after impact to the birtch tree. Lets forget rest of wing. Asymetric lift necessarily caused uncontrolled roll and after secound contact with wires of HV line. After it, the part of wing was completly separated and find on the ground. Where is problem? MAK report is not in conflict with this scenario.
Binienda...argued that...the machine could have lost only a small edge of the wing and this would not have influenced the stability of the plane.
