The Boeing Company Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 777-200 and -300 series airplanes. The existing AD currently requires revising the airplane flight manual (AFM) to include in-flight procedures for pilots to follow in certain cold weather conditions and requires fuel circulation procedures on the ground when certain conditions exist. This new AD retains the fuel circulation procedures. This new AD also revises the AFM procedures required by the existing AD. This AD results from a report of a single-engine rollback as a result of ice blocking the fuel oil heat exchanger. We are issuing this AD to prevent ice from accumulating in the main tank fuel feed system, which, when released, could result in a restriction in the engine fuel system. Such a restriction could result in failure to achieve a commanded thrust, and consequent forced landing of the airplane.

Airbus Model A330 Airplanes, and Model A340-200 and A340-300 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A330, A340-200, and A340- 300 series airplanes. That AD currently requires repetitive inspections of a certain bracket that attaches the flight deck instrument panel to the airplane structure; related investigative and corrective actions if necessary; and replacement of the existing bracket with a titanium- reinforced bracket, which ends the repetitive inspections in the existing AD. This new AD adds requirements only for airplanes on which the existing bracket was replaced with a titanium-reinforced bracket in accordance with the existing AD. The additional requirement is a one- time inspection to determine if certain fasteners are broken or cracked, and corrective actions if necessary. This AD results from a report that incorrect torque values could damage the bracket. We are issuing this AD to prevent a cracked bracket. Failure of this bracket, combined with failure of the horizontal beam, could result in collapse of the left part of the flight deck instrument panel, and consequent reduced controllability of the airplane.

This amendment adopts a new airworthiness directive (AD) for the Trimble or FreeFlight Systems 2101 I/O Approach Plus global positioning system (GPS) navigation system (2101 I/O Approach Plus system) that requires a software upgrade for this system. This amendment is prompted by an incident that led to the discovery of several annunciation errors with the 2101 I/O Approach Plus system. The actions specified by this AD are intended to prevent a pilot from making an unsafe decision based on erroneous information provided by the 2101 I/O Approach Plus system, which could result in loss of control of the aircraft.
