Shouldn't QF contact airlines who had their aircraft maintained by SIAEC in the past to get clarification? Also, can't CASA ask to inspect SIA aircraft that arrive in Australia? There are 90 flights to choose from every week??
If the allegations are THAT serious, they threaten the lives of not only pax who take QF aircraft, but also pax who take SQ aircraft and the over 80 airlines who have/had aircraft maintained by SIAEC. I'm not sure how SIAEC could get away with dodgy maintenance for 80 airlines, but if they did, surely something would have been done about it by now? Or are these experiences unique only to QF aircraft?
