Reading between the lines, it appears these panels were incorrectly replaced after maintenance in Indonesia.
If this is so and it was ferried back to Singapore to continue revenue ops, then I reckon it's a major problem. Would you drive your car out of the workshop with dodgy brakes after a service???
I can NOT believe the fuss being made here over NOTHING.
It was NOT brakes, it was a couple of panels in the cabin, now unless ''ferry flight'' is secret code for something and means something different to what it has meant for the last 50 years, the aircraft was ferried (NO PAX) to Singapore.
NO PROBLEMS, could have had virtually NO cabin fixtures as long as there were NO pax, and there was enough seats and emergency equipment for the Crew.
As long as it was rectified, which it apparently was before any revenue flight.
