Abstract
The FAA is adopting a new airworthiness directive (AD) for certain serial numbers (SNs) of Rolls-Royce Deutschland Ltd. & Co KG (RRD) Model Tay 650-15 turbofan engines. This action requires initial and repetitive visual inspections of low pressure (LP) turbine stage 2 rotor discs and LP turbine stage 3 rotor discs on certain SNs of engines, for corrosion. This AD is prompted by reports of excessive corrosion found during disc inspection. The actions specified in this AD are intended to prevent uncontained LP turbine stage 2 rotor disc or LP turbine stage 3 rotor disc failure due to excessive corrosion, and damage to the airplane.
