Eclipse Aviation Corporation Model EA500 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Eclipse Aviation Corporation (Eclipse) Model EA500 airplanes. This AD requires you to incorporate information into the Limitations section of the airplane flight manual (AFM) that will require operation only in day visual flight rules (VFR), allow only a VFR flight plan, and maintain operation with two pilots. This AD is being issued because of three instances of loss of primary airspeed indication due to freezing condensation within the pitot system. The loss of air pressure in the pitot system could cause the stall warning to become unreliable and the stick pusher, overspeed warning, and autopilot to not function. The concern is heightened by the aerodynamic characteristics of the Eclipse Model EA500 airplane, which relies on the stall warning and the stick pusher to alert the pilot prior to the loss of aircraft control. The standby airspeed is reliable and not affected by this failure mode. A temporary AFM revision prohibits operation in instrument meteorological conditions (IMC), requires two pilots, and limits the airspeed and altitude envelope if the event occurs in flight. The AFM limitations and FAA operational rules allow Model EA500 flight crews to file an instrument flight rule (IFR) flight plan even though the airplane is not approved for flight in IMC. This potentially causes an undue workload burden and confusion when the pilot has to refuse any instructions that take them into IMC. We are issuing this AD to prevent an unsafe condition when Air Traffic Control's (ATC's) ability to maintain traffic separation is compromised because an airplane on an IFR flight plan cannot accept a flight plan into IMC.

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2007-09-51, sent previously to all known U.S. owners and operators of the specified MD Helicopters, Inc. (MDHI), model helicopters by individual letters. This AD requires, before further flight, removing each affected tail rotor blade assembly and inspecting the bore of the tail rotor blade root fitting. If the blade assembly does not have a smooth radius, the AD requires replacing it. The AD also requires identifying each airworthy tail rotor blade assembly with the applicable helicopter model. This amendment is prompted by a report of an accident after the loss of a tail rotor blade. The actions specified by this AD are intended to prevent the failure of a tail rotor blade and subsequent loss of control of the helicopter.

General Electric Company (GE) CF6-80 Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for GE CF6-80 series turbofan engines with fuel shroud retaining rings, part number (P/N) J204P0084, installed. This AD requires replacing those retaining rings with a more robust design fuel shroud retaining snap ring. This AD results from two events of external engine fuel leakage and a subsequent under-cowl engine fire. We are issuing this AD to prevent an under-cowl engine fire and damage to the airplane during an engine high vibration event.

General Electric Company CF34-10E Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF34-10E series turbofan engines. This AD requires revising the combustor case published life limit and removing combustor cases from service before reaching a reduced life limit. This AD results from GE's evaluation of the effects to the combustor case due to installing version 5.10 software in the full-authority digital electronic control (FADEC), and revising the combustor case published life limit. We are issuing this AD to prevent uncontained combustor case failure resulting in an in-flight engine shutdown and possible damage to the airplane.

General Electric Company (GE) CF6-80C2B Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for GE CF6-80C2B series turbofan engines with electronic control units (ECUs), installed on Boeing 747 and 767 series airplanes. This AD requires installing software version 8.2.Q1 to the engine ECU, which increases the engine's margin to flameout. This AD results from reports of engine flameout events during flight, including reports of events where all engines simultaneously experienced a flameout or other adverse operation. Though the root cause investigation is not yet complete, we believe exposure to ice crystals during flight is associated with these flameout events. We are issuing this AD to provide increased margin to flameout, which will minimize the potential of an all-engine flameout event caused by ice accretion and shedding during flight.

General Electric Company (GE) CF34-10E Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for GE CF34-10E series turbofan engines. That AD currently requires removing the fuel inlet strainer from main fuel pump (MFP) part number (P/N) 2043M12P03, installing a certain replacement flange as an interim repair, remarking the MFP to P/N 2043M12P04, and performing initial and repetitive visual inspections of the main fuel filter. This AD requires removing MFPs, P/Ns 2043M12P03, 2043M12P04, 837600-3, and 837600-4, from service and installing an improved MFP with a different P/N. This AD results from GE determining that the cause of MFP fuel strainer failure is a design problem with the strainer. We are issuing this AD to prevent engine in-flight shutdown due to MFP malfunctions.
