Abstract
The FAA is superseding an existing airworthiness directive (AD) for GE CF34-8E series turbofan engines with certain part number (P/N) full authority digital electronic controls (FADECs) installed. That AD currently requires removing certain P/N FADECs. This superseding AD requires removal of 12 more P/Ns of FADECs. This AD results from 20 additional reports received of loss of thrust control events since AD 2008-16-01 was issued. We are issuing this AD to prevent loss of thrust control of the airplane.
