The problem here is clearly political. Somebody made the decision to fire these instructors; that decision was surely supported by senior management and then the government.

What should happen here is that the FAA, EU, and other countries that were originally involved in getting the Koreans to hire these expat instructors in the first place -- these countries should demand final say over all instructor personnel decisions.

This will mean the Koreans basically giving up control of their training program, which will be a huge piece of humble pie for them to eat. But there is no other solution. Either the pilots will be trained properly or they will continue making entirely preventable mistakes and killing people.

EDITED to add clarification: I know nothing about flying planes. My comment is about organizational dysfunction.

OH, and another thought: I don't know anything about this forum except that it calls itself a "Rumour Network". The fact that this post was deleted makes me wonder -- who is keeping issues like this from being aired? It's clear that the author has nothing against Koreans per se -- he just doesn't like to see incompetent pilots flying aircraft.
