It certainly looks like Tiger have been struggling to meet their regulatory obligations for a long time. Were concerns raised when CASA was assessing their initial application for the AOC in 2007. To get to this stage is very serious and as FlexibleResponse suggests was perhaps the last cheese before the accident. Clearly systems and processes have failed that should have ensured the problems were picked up and corrected far earlier. I would like to see Tiger meet the standards and return to flying.
