Sandbank, how many time does an aircraft return to stand with a snag, engineer attends. Fixes problem or defers in accordance with the MEL. Aircraft is fit and SAFE to fly. It is not a test flight!!!
Crew arrive at aircraft in morning. APU fails to start. Test flight required!?!?!?!?!?!?
Sandbank are you posting so that later on someone from the media can refer to a "pilots website" where someone has got "proof" the airline were not carrying out maintenance and the aircraft was actually on a test flight?????
