Video: LN-OJF Accident investigation status

On 29 April 2016, an Airbus Helicopters H225 suffered a fatal accident off Norway. Official investigators, supported by Airbus Helicopters, identified the chain of events leading up to the accident and were able to isolate the contributing factors. This video summarises what they discovered, and explains how Airbus Helicopters has improved the safety of the H225.

LN-OJF accident statement, July 7, 2017

Airbus Helicopters expresses its deep regret for the tragedy which claimed the lives of 13 people off Turøy in Norway in 2016 and we offer our sincere and profound sympathies to the bereaved families.

Airbus Helicopters welcomes the lifting of the H225 and AS332 L2 flight ban by the UK & Norwegian national aviation authorities.

The safety case, originally approved by EASA in October 2016, has subsequently seen additional Airbus Helicopters’ improvements as a result of the learnings from the investigation which have, as is standard, been reinforced with EASA Airworthiness Directives.

Today, pending any further findings by the AIBN, this safety case is based on a design change addressing fatigue failure, improved spalling detection and increased reliability. This has been achieved with a series of measures including:

  • An improvement of the MGB’s design robustness through the replacement in all gearboxes of the part that broke in the LN-OJF accident with a more resistant part, as well as a significant reduction in the life limit of this type of part (from 4000 to 1000 flight hours).
  • An improved spalling detection system based on a new Full Flow Magnetic Plug (FFMP) to detect particles in the oil, a strengthened inspection criteria and equipment allowing a more detailed analysis of these particles, including very small ones.
  • A new quality assurance process better able to protect critical dynamic components throughout their maintenance history. This notably includes a new packaging system equipped with shock sensors.

This is the result of learnings from the investigation and the need to raise the bar in safety across industry to ensure that the strictest safety requirements are met.

Although Airbus Helicopters welcomes the lifting of the H225 flight ban by Norwegian and UK aviation authorities, we understand that this will not necessarily result in immediate passenger flights as there is a lot of work to be done to restore confidence in the aircraft.

Airbus Helicopters will continue to work on supporting the aircraft’s return to operations as and when required by customers.

A message from Guillaume Faury, Chief Executive Officer

"The 2016 accident was an immense tragedy. My team and I were deeply shocked. We build helicopters to help people and to transport them safely, and to save lives - and this accident goes against everything we believe in.

We are working with the authorities to find out what happened, and we will use the findings to set new safety standards across the helicopter industry

We know there will be questions and they demand answers. We are determined to be as transparent as possible. We will be keeping the families of those who died, our customers, employees, and other stakeholders, fully informed throughout the investigation.

To support that process, we have created this Super Puma Information Centre. This website will supply regular updates on the investigation, as well as the lessons and actions that result from it.

I cannot change the past, and all of us at Airbus Helicopters wish this tragedy had never happened, but we are determined to ensure it is never repeated."
