AD NUMBER: 2008-16-01
MANUFACTURER: General Electric
SUBJECT: Airworthiness Directive 2008-16-01
SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for GE CF34-8E series turbofan engines with certain
part number (P/N) full authority digital engine controls (FADECs)
This AD requires reprogramming the FADEC software from version
8Ev5.40 to an FAA-approved software version.
This AD results from six loss of thrust control events from the
same software fault scenario.
We are issuing this AD to prevent loss of thrust control and
controllability of the airplane.
