Airworthiness Directives; CFM International, S. A. CFM56-5B Series Turbofan Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
––––––––––––––––––––––––––––––––––
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for CFM International, S. A.
CFM56-5B series turbofan engines. This AD requires reviewing exhaust gas temperature (EGT)
monitoring records to determine EGT deterioration margin, and for airplanes where both engines
have greater than 80° centigrade (C) deterioration of EGT margin, borescope-inspecting the highpressure
compressor (HPC) of both engines. This AD also requires removing from service any engine
that does not pass the borescope inspection, and if both engines pass, removing and replacing one of
the engines with an engine that has 80 °C or less deterioration of EGT margin. This AD also requires
continuous monitoring of EGT margin on engines in service, to prevent two engines on an airplane
from having greater than 80 °C of deterioration of EGT margin. This AD results from an Airbus
A321 airplane powered by CFM56-5B1/P turbofan engines experiencing HPC stalls during climb out
after takeoff. We are issuing this AD to prevent HPC stalls, which could prevent continued safe flight
or landing.
DATES: This AD becomes effective December 31, 2008.
We must receive any comments on this AD by March 2, 2009.
