2004-09-10: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747 series airplanes. This AD requires a one-time inspection of the potable water and drain lines in the forward and aft cargo compartments for indications of overheating of the heater tape, exposed foam insulation, missing or damaged protective tape, or debris around the potable water fill and drain lines; and corrective action, if necessary. This action is necessary to prevent overheating of the heater tape on potable water fill and drain lines, which may ignite accumulated debris or contaminants on or near the potable water fill and drain lines, resulting in a fire in the airplane. This action is intended to address the identified unsafe condition.
2004-09-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 and 400D series airplanes. This action requires installation of tie bars on the rails of the center passenger service units (PSU) panel in Zone A. This action is necessary to prevent PSU panels from moving and falling from the PSU support rails during takeoff and landing, which could result in injury to passengers and could impede evacuation of the passengers in an emergency situation. This action is intended to address the identified unsafe condition.
2004-09-05: This amendment adopts a new airworthiness directive (AD); applicable to certain Cessna Model 500, 501, 550, and 551 airplanes; that requires a one-time inspection of the brake stator disks to determine to what change level they have been modified (if any), and related investigative and corrective actions if necessary. This AD also requires that the existing markings on the piston housing of certain brake assemblies be eliminated. The actions specified by this AD are intended to prevent wheel lockups that may be caused by cracked or broken brake stator disks becoming jammed in the brake assembly and preventing rotation. Such jamming of the brake assembly may result in reduced directional control or braking performance during landing. This action is intended to address the identified unsafe condition.
2004-08-16: The FAA is adopting a new airworthiness directive (AD) for certain serial numbers (SNs) of NARCO Avionics Inc. AT150 transponders. This AD requires modification to the transponder by adding a resistor and transistor to the circuit board. This AD results from reports of AT150 transponders not recognizing and responding properly to Mode S interrogations from Mode S ground stations and Traffic Alert and Collision Avoidance System (TCAS-II) airborne equipment. We are issuing this AD to prevent loss of aircraft airspace separation and the possibility of mid-air collision.
2004-08-13: The FAA adopts a new airworthiness directive (AD) for certain BURKHARDT GROB LUFT-UND RAUMFAHRT GmbH & CO KG (Grob) Models G103 Twin ASTIR, G103 TWIN II, G103 TWIN III ACRO, and G103 C Twin III SL sailplanes. This AD requires you to replace the center of gravity (CG) release hook attachment brackets with brackets of improved design. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent abnormal or uncontrolled sailplane release due to cracked CG release hook attachment brackets. This condition could result in reduced or loss of sailplane control.
2004-08-05: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A300 series airplanes, that currently requires either a one-time ultrasonic inspection, or repetitive visual inspections and eventual ultrasonic inspection, to detect cracking of the longitudinal skin splice above the mid-passenger door panels, and corrective actions if necessary. This amendment requires repetitive ultrasonic inspections to detect cracking of certain skin lap joints in additional areas of the fuselage and repair if necessary. This amendment also expands the applicability of the existing AD to include additional airplanes. The actions specified by this AD are intended to detect and correct cracking of certain skin lap joints, which could result in reduced structural integrity and decompression of the airplane. This action is intended to address the identified unsafe condition. DATES: Effective May 26, 2004. The incorporation by reference of certain publications, as listed in the regulations, is approved by the Director of the Federal Register as of May 26, 2004. The incorporation by reference of a certain other publication, as listed in the regulations, was approved previously by the Director of the Federal Register as of February 22, 2000 (65 FR 5756, February 7, 2000).
2004-07-11: This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 767-400ER series airplanes, that requires repetitive high frequency eddy current inspections of the aft lower lugs of the deflection control track of the outboard flap for cracks, and replacement of any cracked deflection control track with a new track assembly. This action is necessary to prevent fatigue cracking in the aft lower lug run-out region of the deflection control track. Fatigue cracking of the deflection control track, if not detected and corrected in a timely manner, could result in the loss of the secondary load path for the outboard flap, resulting in the loss of the outboard flap and consequent reduced controllability of the airplane in the event that the primary load path also fails. This action is intended to address the identified unsafe condition.
2004-07-18: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, that requires replacement of landing gear control handle components with new, improved components. This action is necessary to prevent an inability to lower or retract the landing gear using the landing gear control handle, which could result in use of Emergency Procedures using the landing gear manual release. This action is intended to address the identified unsafe condition.
2004-07-20: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 and -400D series airplanes. This action requires an inspection to determine the routing configuration of wire bundle W4489 and related investigative/corrective actions. This action is necessary to prevent possible interference between wire bundle W4489 and the receptacle housing of the chiller boost fan, drain tubes, and adjacent structure, which could result in damage to the wire bundle and consequent arcing and fire. This action is intended to address the identified unsafe condition.
2004-05-28: This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters that requires installing a tail rotor blade (blade)-to-torsion bar attachment tuning weight assembly on each blade of the Quiet Fenestron tail rotor and replacing each blade attachment bushing. This amendment is prompted by the discovery of tail rotor induced vibrations during flight tests. The actions specified by this AD are intended to prevent vibration in the tail rotor and the pilot's anti- torque pedals, blade pitch control failure, and subsequent loss of control of the helicopter.
