"I wonder if the NCAA will accept and validate a pilot license from Indonesia with a p/c from the UK?" These are the same NCAA guys who knowingly validated them every year with fake checks! The NCAA workers do what's in their best financial interests, not what is in the best interest of the poor souls who must ride on a 5N registered plane. The only thing that could possibly change their behaviour is the shame that will fall upon them after Max Air kills a plane load of people during the upcoming Umrah and Hajj season. Should this happen, all communications, documents and warnings sent to the NCAA will be released to the international press and the world will decide how well the NCAA has conducted regulatory oversight of an airline under their control.
