My understanding is that SIN & CGK are the last of the Asian ports to lose QF engineers - BKK went to CX engineers last year, HKG has been HAECO for a long time. The whole operation will be managed by the head of engineering in LAX.
Losing our own staff in SIN is a huge surprise as we have a large number of flights which over the years has lead to some major engineering challenges.
This looks like another one of Boston Consulting Group's ideas to reduce costs irrespective of the long term consequences.
