How so, GB? Surely if they're being worked on they can't fly - the replacement schedule that was agreed was that the work would be done when the aircraft came in for their regular maintenance check. People have been arguing that the response should have been stronger than that - so me asking how that would have worked is a genuine question, which is:
Given an AD that required work before the type was allowed to fly again and the schedule that was actually agreed with the SB as extreme ends of the scale, what is there in terms of middle ground that would have satisfied those who were saying that the latter was not enough?
