If the Vikings are regenerated, I presume the fleet will still need to undergo either a Life Extension Programme (RA5724) or an OSD Extension Programme (RA5725) if they are to go on until 2025. Both of these are substantial pieces of work which should have been completed some time ago. Does the PT have the capacity to carry this out at the same time as the recovery, and if not will the MAA require it to be completed before the aircraft can return to service?
