If airbus design life and inspection schedules are based on a say 75% packs on and 25% pack off take-offs, and operators ask us to make 100% packs off take-offs, there is the seed of a doubt re this as a lifetime procedure for these aircraft.
Hard to think that it is serious in the short term, and most of these operators will no longer lease them when these aircraft are near the end of their life. So why should they care?
