These engines are installed on, but not limited to, Airbus 330 series airplanes.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) The affected IP Turbine Discs, P/N FK20795, must be removed from service prior to attaining the following number of Cycles Since New (CSN):
| Serial No. | Removal limit in CSN |
|---|---|
| CREB452 | 7,960 |
| CREB216 | 7,930 |
| CREB322 | 7,500 |
(2) For detailed instructions, refer to Rolls-Royce RB211 Propulsion System Non-Modification Service Bulletin RB211-72- AF734 original issue, section 3. Accomplishment Instructions.
