Latest statement (May 3) from Airbus Helicopters on EC225 situation


3 May – Airbus Helicopters welcomes the announcement made by the Accident Investigation Board Norway (AIBN) today.

The investigation will now solely be focused on potential root causes of a technical failure, such as design, production, and/or maintenance.

Airbus Helicopters continues to provide its full support to the AIBN investigation.

At this stage and based on the latest information, preliminary inspection of the main gearbox vertical shaft shows no link with the 2012 ditching events.

In addition to the SIN 3031-S-00 (see below) and based on the on-going root cause analysis process, precautionary measures are requested:


  • An airworthiness directive has been issued requesting measures newly defined in the EASB 53A058 and additional one-off maintenance checks.
  • The EASB 53A058 requests the verification of the correct installation of all MGB suspension bar attachments for the EC225LP. Similar measures will be published shortly for the EC725AP in a specific ASB.
