Airworthiness Directives; Airbus Model A330-200 and A330-300 Series Airplanes, and Model A340-200, A340-300, A340-500, and A340-600 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Investigation conducted by Thales on probes revealed oil residue between the stator and the rotor parts of the AoA [angle of attack] vane position resolvers. This oil residue was due to incorrect cleaning of the machining oil during the manufacturing process of the AoA resolvers. At low temperatures, this oil residue becomes viscous (typically in cruise) causing lag of AoA vane movement. Such condition could lead to discrepant AoA measurement. If not corrected, and if two or three AoA probes were simultaneously affected and provided wrong indications of the AoA to a similar extent, it could lead to a late activation of the angle of attack protection, which in combination with light at high angle of attack would constitute an unsafe condition.

Airworthiness Directives; The Boeing Company Model 727 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Model 727 airplanes. This proposed AD would require inspections for scribe lines in the fuselage skin at skin lap joints and butt joints, the skin at certain external approved repairs, the skin around external features such as antennas, and the skin at decals and fairings; and related investigative and corrective actions if necessary. This proposed AD results from reports of scribe lines found at skin lap joints and butt joints, around external repairs and antennas, and at locations where external decals had been cut. We are proposing this AD to detect and correct scribe lines, which can develop into fatigue cracks in the skin and cause rapid decompression of the airplane.
Airworthiness Directives; Eurocopter France (ECF) Model SA330F, G, and J; and AS332C, L, L1, and L2 Helicopters
We propose to adopt a new airworthiness directive (AD) for the specified ECF model helicopters. This proposed AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI AD states that EASA received a report of a rear hinged door on a Model AS332L1 helicopter opening in flight without loss of the door. Examinations revealed incorrect positioning of a door catch that resulted in incorrect locking and uncontrolled opening of the door. This condition, if not detected and corrected, can lead to the loss of the hinged door in flight, damage to the main or tail rotor blades, and subsequent loss of control of the helicopter.
Airworthiness Directives; BAE Systems (OPERATIONS) LIMITED Model BAe 146 and Avro 146-RJ Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: In June 2000, prompted by a crack found at the top of the NLG [nose landing gear] oleo, BAE Systems (Operations) Ltd issued Inspection Service Bulletin (SB) 32-158. This SB was classified mandatory by the UK [United Kingdom] Civil Aviation Authority under AD number 002-06-2000, requiring repetitive non- destructive testing (NDT) inspections for cracking on the upper end of the NLG oleo. The AD also provided an optional terminating action for the repetitive inspections, by embodiment of Messier-Dowty SB.146-32- 150. As part of a recent accident investigation, the examination of a fractured NLG main fitting showed that Messier-Dowty [M-D] SB.146-32- 150 had not been accomplished, although the records indicated that it had been. BAE Systems has determined that more NLG units could be similarly affected. These NLG units have been overhauled at Messier Services in Sterling, Virginia, in the United States. This condition, if not corrected, could result in NLG failure. Subsequently, investigation and analysis by M-D has identified the need for a reduction of the inspection threshold and the repetitive inspection interval for the affected NLG units and has replaced M-D SB 146-32-149 with M-D SB 146-32-174. The unsafe condition is cracking of the NLG, which could adversely affect the airplane's safe landing. The proposed
Airworthiness Directives; The Boeing Company Model 777-200 and -300 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Model 777-200 and -300 series airplanes. This proposed AD would require installing new operational software in the cabin management system, and loading new software into the mass memory card. This proposed AD results from an in-flight entertainment (IFE) systems review. We are proposing this AD to ensure that the flightcrew is able to turn off electrical power to the IFE system and other non-essential electrical systems through a switch in the flight compartment in the event of smoke or flames. In the event of smoke or flames in the airplane flight deck or passenger cabin, the flightcrew's inability to turn off electrical power to the IFE system and other non-essential electrical systems could result in the inability to control smoke or flames in the airplane flight deck or passenger cabin during a non- normal or emergency situation.
Airworthiness Directives; McDonnell Douglas Corporation Model DC-10-10, DC-10-10F, DC-10-30, DC-10-30F (KDC-10), DC-10-40, and DC-10-40F Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Model DC-10-10, DC-10-10F, DC-10-30, DC-10-30F (KDC-10), DC-10- 40, and DC-10-40F airplanes. This proposed AD would require installing a support bracket and coupler on the left and right wing-to-fuselage transition, and metallic overbraid on the left and right leading edge wire assembly. This proposed AD results from fuel system reviews conducted by the manufacturer, as well as reports that the fuel quantity system was affected by lightning-induced transients. We are proposing this AD to prevent lightning-induced transients to the fuel quantity indication system, which could cause voltage levels to go beyond original design levels between fuel tank probes and structure, and become a potential ignition source at the fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Learjet Inc. Model 45 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Learjet Inc. Model 45 airplanes. This proposed AD would require replacing aluminum fire extinguisher discharge tubes with new, improved tubes; checking the fire extinguisher container for certain serial numbers; replacing fire extinguisher containers that have affected serial numbers; inspecting the pressure indicator on certain fire extinguisher containers for discrepancies; and performing corrective action if necessary. This proposed AD results from a report of accidental discharge of a fire extinguisher container and damage to an aluminum discharge tube. Investigation revealed that following the discharge an inaccurate pressure indication, due to the indicator dial being incorrectly staked, showed that the container was fully charged. We are proposing this AD to prevent inaccurate pressure readings and subsequent damage to the discharge tubes during operation, which could result in failure of the fire extinguisher system and an uncontained fire in an emergency situation.
