c100driver is correct to a point, the operator dictates what they want fixed, all airlines do it. What is at question is if cannon plugs and wiring being disconnected and other problems were approved. The MRO is usualy responsible for the work and certification, the reps are there to oversee proceedings. Depending on the number of reps most of these problems would not have been noticed until departure and by then its too late. As the a/c was probably a positioning flight back to Syd cabin defects would not be picked up until being prepared for the next flight. It would be a good bet that pressure by QANTAS to get the plane back to SYD would be extremely high. So who is to blame for the state of the a/c? The MRO, the flight crew, the reps or QANTAS management. Probably all of them, but mostly QANTAS mismamagement for having to put the aircraft there in the first place.
