MANUFACTURER: General Electric Company (GE) CF6
Turbofan Engines SUBJECT: Airworthiness Directive 2011-23-04 ACTION: Final rule
SUMMARY: The FAA is superseding an existing
airworthiness directive (AD) for the engines identified above. That
AD currently requires initial and repetitive visual inspections of
the forward engine mount assembly side links for cracks, stripping
and reapplying the Sermetel W coating on the side links at every
exposure of the side link. This new AD requires those same
inspections, stripping and reapplying the Sermetel W coating, and
adds two part numbers to the applicability. This AD was prompted by
a review of the inspection program, which revealed that GE had
omitted two affected side link part numbers from the applicability.
The FAA is issuing this AD to prevent failure of the side links and
possible engine separation from the airplane.
