The RR event and the 787 battery fire both have fixes approve by the regulator. That makes them equal in the eyes of the regulator (nothings perfect)
All the recent talk on this thread is about 787 incidents which have little to any significance to the same level of unsafe conditions in either earlier event.
Time to move on with correlations and look at new events with a safety weighted outlook like any other new product entering service and being adjusted to by the maintenance actions etc.
