EC225 Return to Service

2012 – Incident description

Two controlled ditching events in the North Sea had occurred in 2012

No power transmission loss

No one on board was injured and everyone was brought back to land safely. The helicopter remained afloat thanks to its emergency floatation gear and was recovered.

Main Gear Box Lubrication Warnings came on and resulted in the crew deciding to perform immediately a ditching, as required by the flight manual.

Loss of MGB lubrication came from a rupture of the bevel gear vertical shaft

Understanding and protective measures

After 7 months of research, testing and collaboration with official services and customers, the shaft technical issue on the 225 is fully understood and mastered.

The crack can only appear with an unlikely combination of factors. This explains why it appeared only after 7 years and 300.000 flight hours for the 225/725 fleet.

A phenomenon called active corrosion has been identified. It proved to play an important role.

New prevention and detection measures in place increase safety beyond certification levels. They are integrated in the standard maintenance procedures by the operator.

Eurocopter has certified as first company worldwide a system of vibration monitoring in the cockpit.

Return to Service

The investigation methodology and results have been validated by independent experts, Shainin Engineering and Georgia Tech Research Institute, chosen by our operators.

The approval by the European authorities has been released, the flight restrictions of the CAA UK and Norway have been lifted.

With the safety barriers implemented the in flight shaft rupture risk is now eliminated.

As a long-term solution, Eurocopter has launched the shaft redesign.

More than 60% of the fleet had kept on flying, all modification kits have been distributed and the Return to Service is on track.

EC225 has regained full operational performance

AS332 L2 Accident 23rd Aug. 2013in North Sea near Shetland Islands

AS332L2 Accident Friday 23rd Aug

The accident23rd Aug at 6:20pm an AS332 L2, 16 pax, 2 crew, crashed in the North Sea on return flight from oil rig in approach to Sumburgh Airport, the helicopter turned over, 4 fatalities

Technical data of crashed aircraft:In operation since 2002MGB vertical shaft: carburizedFlight hours: 17,000

Sat 24th: HSSG suspends all Super Puma Flights (L, L1, L2 and 225) EC issued 3 Safety Information Notices (SIN) on 24, 25 and 29 August

Investigation status: fuselage, MGB, rotor head, engine and cockpit parts recoveredCVFDR tracked and recovered since 29 August

One week after accident

HSSG Press release:

“The HSSG supports the return to active service of all variants of the Super Puma fleet:• The fleet of L and L1 helicopters shall return immediately to commercial service• The EC225, arguably the most examined helicopter in modern history,

shall proceed along its original return to service plan• However, in recognition of the understandable sensitivities around the immediate return

to service of the L2 fleet (the specific type involved in Friday’s incident), this type will be initially re-introduced for non-passenger revenue operations only.”

AAIB Press release:

“The evidence currently available suggests that the helicopter was intact and upright when it entered the water. It then rapidly inverted and drifted northwards towards Garths Ness. The helicopter was largely broken up by repeated contact with the rocky shoreline.”(29.08.2013)

One week after accident

CAA UK

“Based on all the information currently available, we do not believe that the accident was caused by an airworthiness or technical problem, and consider that the decision by the operators to resume Super Puma flights is appropriate. We would not allow a return to service unless we were satisfied that it was safe to do so. We will review the position if any new evidence comes to light.”
