- 19 engines, all serial numbers. These engines are known to be installed o n, but not limited to, Boeing 747 series and Lockheed Martin Corporation L

- 1011 (TriStar) series aeroplanes.
Reason: Since 2006, a number of l ow p ressure t urbine (LPT) Stage 3 b lade failure s have been reported , each resulting in engine i n - f light shut

- down

. Engineering analysis on those occurrences indicates that blades with an accumulated life of 11 0 00 flight cycles ( FC ) or more have an increased risk of failure

. This condition, if not detected and corrected, could lead to release of LPT Stage 3 blade debris and consequent (partial or complete) loss of engine power, po ssibly resulting in reduced control of the aeroplane

. T o address this potential ly unsafe condition, RR issued Alert Non

- Modification Service Bulletin (NMSB) RB.211

- 72

- A H790 to introduce a life limit for certain LPT Stage 3 blades

. For the reasons described above, this AD requires implementation of the reduced life limit and replacement of the affected L PT Stage 3 blades that have already reached or exceeded 11 0 00 FC since new.
