I was told that a Swiss Global Express crew just recently (after the crash in Dec.) orderered de-icing there. Looking at his airplane in disbelief, the pilot saw ice hanging down from the stabilizer (like in those deep caves) after the de-icing crew was done. The ground crew also had applied the fluid from the trailing edge, because they said they couldn't get to it from the other side...
This sounds like a serious potential for an accident to happen. We can get used to thorough or more than thorough de-ice/anti-ice here in the west and not think that in lesser developed locations improper de-icing techniques could lead to wing contamination on takeoff due to incompetence or perhaps even intentionally not using enough fluid. In reality many of us, myself included are assuming that the de-icing crew are doing a competent job because we can't see the critical surfaces from the cockpit. Beware.
