M International has announced its subsidiary Keystone Turbine Services, LLC (KTS) has received Rolls-Royce approval to begin repairing a select part number Outer Combustion Case (OCC) for the C28, C30, C40 and C47 Series gas turbine engines.
“As a Rolls-Royce M250-certified Authorized Maintenance, Repair and Overhaul Center [AMROC], KTS is pleased to offer this critical repair,” said John Fraser, general manager at KTS. “The affected part number is 23030911, and we’re ready to apply our new two-piece reinforcing wire patches to your OCC, which meets the requirements of the new Commercial Engine Bulletin [CEB]. We also offer overhauled exchange OCCs should you require quicker delivery.”
