Sadly in the real world the standards of maintenance vary (as GSM found to their cost) and as a contract licensed engineer who has worked for most of the big european and middle eastern MRO,s over the last twenty years (including jet 2 at LBA) i can say with some certainty monarch are one of the very best, as a contractor i have no axe to grind, im saying it as it actually is , if i had to select one company to maintain my B757,s it would without doubt be monarch
ps daddy, what exactly do you mean by the "validity "of a defered defect?
