Airbus Helicopters Helicopters
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2004-01-51, which was sent previously to all known U.S. owners and operators of the specified Eurocopter France (Eurocopter) model helicopters by individual letters. This AD requires, before further flight, for helicopters with less than 10 hours time-in-service (TIS) since installing a main or combiner gearbox received from Eurocopter Marignane, France, replacing these affected gearboxes with appropriate airworthy gearboxes received from another source. This action is prompted by a report of a free wheel unit slipping during the single engine phase of an acceptance flight that resulted in an engine overspeed and an engine shutdown. The actions specified by this AD are intended to prevent engine overspeed, an engine shut-down, and subsequent loss of control of the helicopter.

General Electric Company CF34-8E Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF34-8E series turbofan engines, with certain serial number (SN) master variable geometry (VG) actuators installed. This AD requires initial and repetitive reviews of the airplane computer systems for master VG actuator fault messages. This AD also requires replacement of actuators reported faulty by the Full Authority Digital Engine Control (FADEC). This AD results from nine reports of CF34-8C master VG actuator electrical signal faults, one report of which was a dual-channel fault, resulting in the FADEC commanding the engine power to idle. We are issuing this AD to prevent VG master actuator dual-channel electrical signal faults which will cause an uncommanded reduction of thrust to idle with a subsequent loss of the ability to advance thrust above idle; and which could result in a multi-engine loss of thrust if dual-channel faults occur on more than one engine simultaneously.

Rolls-Royce Corporation (Formerly Allison Engine Company) AE 3007 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Corporation (RR) (formerly Allison Engine Company) AE 3007A, AE 3007A1/1, AE 3007A1/2, AE 3007A1, AE 3007A1/3, AE 3007A1P, and AE 3007A3 turbofan engines. That AD currently requires initial and repetitive inspections for bearing material contamination of the engine oil system. This AD requires the same inspections but with an extended repetitive inspection interval, and adds terminating actions to the repetitive inspections required by this AD. This AD is prompted by design changes introduced by the manufacturer that reduce the axial load on the No. 1 bearing. We are issuing this AD to prevent the rapid failure of the No. 1 bearing, which could result in smoke in the cabin and an uncommanded in-flight engine shutdown.

General Electric Company (GE) CF6-80 Series Turbofan Engines
The FAA is superseding two existing airworthiness directives (ADs) for GE CF6-80 series turbofan engines with certain stage 1 high- pressure turbine (HPT) rotor disks. Those ADs currently require initial and repetitive inspections of certain stage 1 HPT rotor disks for cracks in the bottom of the dovetail slot. This action retains the initial inspection requirement, as a qualification for the mandatory rework procedures for certain disks, and continues repetitive inspections only for the disks for which the rework procedures are not yet defined. This action requires reworking certain disks before further flight. In addition, this AD expands the population of affected engines and removes certain CF6-80E1 series disks from service. This AD results from the manufacturer's investigation and development of a rework procedure that chamfers the aft breakedge of the dovetail slot bottom. We are issuing this AD to detect and prevent cracks in the bottoms of the dovetail slots that could propagate to failure of the disk and cause an uncontained engine failure.

Air Cruisers Company Emergency Evacuation Slide/Raft System
The FAA is superseding an existing airworthiness directive (AD) for a certain Air Cruisers Company Emergency Evacuation Slide/Raft System. That AD currently requires a one-time unpacking and subsequent repacking of the slide/raft systems, identified by basic part number (P/N) with dash numbers, and serial numbers (SNs) listed in the AD, and mandates repacking of all other slide/raft systems of the same design at the next required normal maintenance schedule of the slide/raft system. This AD contains the same requirements but replaces the specific slide/raft system P/N dash numbers with the word "-series", reduces the number of affected slide/raft systems to the SNs identified in paragraph (g) of the AD, and eliminates mandating the utilization of the applicable Folding Procedures for subsequent repacking of all slide/raft systems of the same design during the normal scheduled maintenance. This AD is prompted by recent information received that Air Cruisers Company has made modifications which have added new dash numbers to the slide/raft system basic P/N. This has affected some of the SN slide/raft systems listed in the AD. We are issuing this AD to prevent failure of the slide/raft to properly inflate, which could impede the emergency evacuation of passengers in the event of an airplane emergency.
