AH has recently added a "Super Puma Information Centre" section to its website. This gives a lot more detail from them and information on the programme to return the H225 and H215 to service. This shows that out of the 341 aircraft affected 49% are now back in service whereas in O&G it is only 15%. Obviously one fact in this is location as many of those 127 are located in UK/Norway where they are formally grounded. The site show the hours being accumulated by the flying aircraft and the total hours accumulated by the types to date. It acknowledges that while they know what happened and have been able to introduce measures to mitigate the risk of a recurrence that more investigation needs to take place to understand why as FNTC noted "in a manner which was unlikely to be detected by the maintenance procedures and the monitoring systems fitted to LN-OJF at the time of the accident".

The failure mode was not what would be expected and despite a huge technical effort there is still no obvious "smoking gun". The metallurgical understanding of the events is now very thorough and it would seem that further work here offers the best chance of getting to the bottom of this one.
