Hi Grunt
The life reduction is to the casting only and is temporary. The next stage is to supply all operators with a casting with additional material around the foot. This will be an interim solution. All the cracks are on one bolt on the rear foot only. The long term solution is to use the casting from the Canadian MHP gearbox which is rated to 29k lbs plus MTOM and which will have a 4000 hour life.
All retrofit parts for all of the S-92 product improvements are supplied free to operators, even back to the first production aircraft S/N 92-006 as well as being incorporated into current production ships.
Sikorsky does not apparently want any customers to have an inferior mod state which is why the company will continue to supply retrofit product improvement parts at no cost to the customer.
