Quote "So Garuda banned after one recent accident but China Airlines not banned after many recent hull losses (last 10 years)."
I think you will find that CAL has made many changes to improve safety over the last few years including mandatory CRM, and new maintenance contracts with the airline manufacturers. It is very rare that I fly a CAL aircraft with any DD items outstanding unlike my previous airline (euro low cost carrier). As I understand it the Capt in the indonesian 737 incident was told to go around 3 times by the FO but chose to ignore him. This is the sort of thing happening still at several airlines around the world and unfortunately it takes international pressure to change, or a string of accidents as has happened here.
