Federal Aviation Administration August 24, 2009 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede 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 proposed superseding AD would require removal of 12 more P/Ns of FADECs. This proposed AD results from 20 additional reports received of loss of thrust control events since AD 2008-16-01 was issued. We are proposing this AD to prevent loss of thrust control of the airplane.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 216: Aeronautical Systems Security (Joint meeting with EUROCAE WG-72).
