AD: CFM International S.A. Turbofan Engines

AD NUMBER: 2015-04-02

PRODUCT: All CFM International S.A. (CFM) CFM56-7B series turbofan engines.

ACTION: Final Rule

SUMMARY: This AD was prompted by a dual engine thrust instability event that resulted in the overspeed and in-flight shutdown (IFSD) of one engine.

This AD requires modification of the engine by removing full authority digital engine control (FADEC) software, version 7.B.V4 or earlier, installed in the electronic engine controls (EECs) on CFM56-7B engines.

The FAA is issuing this AD to prevent a thrust instability event, which could lead to overspeed and IFSD of one or more engines, loss of thrust control, damage to the engine, and damage to the airplane.

DATES: This AD is effective March 31, 2015.
