CASAs job is to review the carriers operation, not the procedures of Manila. Regardless of where the maintenance is done they are only digging here in Australia. It’s up to the operator to ensure it’s up to standard. They want to take risks on cheap engineering well that’s up to them, end result is accidents/fatalities/bad
pr/casa oversight.
Blame the regulator when no action is taken to known serious events. Tiger was grounded for many reasons, not all were publicly known, but they pushed the envelope and showed zero interest in spending money on safety. A continued disregard to acceptable engineering standards without any sort of rectification ends in penalties. Tiger was grounded.
Tiger grounded this jet for 3 weeks to resolve the issue. The Tiger back in the pommy era would not have done this, would keep pushing on, the issues would keep growing, and the regulator dealt with that swiftly.
