I wouldn't be surprised if it was.

Although thinking about it, I would expect that to crack from the inside out, not the outside in.

It all depends on where the imperfections are and the way the loads are placed on the parts. It also depends on the grain boundaries of the metal and how the parts were finished. (heat treating, nitriding etc.)

The fallout continues. Korea has grounded its fleet of KUH-1 Surion helicopters. They are based on the H225/AS332 designs, but were developed and built in Korea with the help of Airbus. Of The 52 in service, 30 need to have their gearbox replaced. Airbus helicopters has sent out an emergency alert service bulletin calling for the replacement of some planetary gears. Airbus will reimburse the Korean government for the expense.

The flight ban put in place by the EASA has been lifted, but the UK and Norwegian bans remain in place.

Airbus has called for replacing one of the two planetary gear configurations. They didn't specify which manufacturer or configuration, but they found one has higher operating stress, which results in more spalling events. They've also reduced time between inspections of the chip detector and oil filters to 10 hours.

Their mechanics are going to love that. That pretty much makes pulling chip detectors part of the daily inspection. If their chip detectors are anything like Sikorsky's, they can be a pain in the ass.

Airbus Helicopters met with regulators to discuss a path to return the H225 helicopters to service. Both Norway and the UK have continued the grounding order issued after the crash.


Airbus Helicopters and officials from the Norwegian and UK civil aviation regulators met earlier this week to discuss the return-to-service path for the H225, sources indicate.

The 11t-class helicopter, and the related AS332 L2, remains grounded by the authorities in those two countries, despite European regulators lifting a ban imposed after a fatal accident in April 2016 in which 13 people were killed.

No details of the discussions have been revealed, however.

Sikorsky grounded all their S92 helicopters the other day, after one gouged into a rig as it landed:




Helicopter manufacturer Sikorsky has grounded all S92 aircraft worldwide for safety checks following an incident on a North Sea platform.
Operators were instructed to carry out the checks immediately, centred on tail rotors. Many of the inspections were completed by Tuesday afternoon. The Air Accidents Investigation Branch (AAIB) is investigating an incident on the West Franklin Platform which happened last month. An S92 experienced a technical fault when it was coming in to land. It left "significant gouge marks" on the deck of the platform.

Better safe than sorry, I guess.

I figured you would all already know about it, about 3 minutes after I wrote that.

The one year anniversary sees another report, and still no definitive cause. They believe that the planetary gear came apart, but not why.

Two bearing companies were identified as making the gear, and investigators found that one of them was three times more susceptible to spalling than the gear made by the other company. They found 22 incidents of spalling between 2001 and 2016,compared to 7 in the same time period by gears made by the other company.

Once operators prove they have the required processes, training, and equipment in place, then Norway and the UK will allow them to start flying the Super Puma again.

Era Group announced a $117M write down in the latest quarter. This was caused by the latest appraisal of their 9 H225 Super Puma helicopters. They have been grounded since the Norway crash, and were valued at $4M each. They should have been valued over $15M.
