2004-01-14: This amendment adopts a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC130B4 helicopters with a certain air intake cowling attachment fitting (fitting) installed. This action requires inspecting for broken or cracked forward fittings. If a broken or cracked fitting is found, inspecting the four center and aft fittings for cracks is required. Replacing broken fittings or certain cracked fittings is also required. This amendment is prompted by reports of cracked and broken fittings; one fitting failed after only 418 hours time-in-service (TIS). This condition, if not corrected, could result in failure of a forward fitting, an excess load on the other fittings, which could cause them to crack and break, which could result in loss of the air intake cowling in flight, and subsequent damage or loss of control of the helicopter, or both.
2004-01-12: This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-135 and -145 series airplanes, that requires operators to inspect the pitot-true air temperature (TAT) relays and the full authority digital engine control (FADEC) electronic interface resistor modules to detect contamination. This AD also requires operators to perform corrective action if necessary, clean the relay/connector pins and sockets, modify the seal between the cockpit console panels and the storm window, and/or install a new protective frame (protective sheets) at the cockpit relay supports. This action is necessary to detect and correct oxidation of the pitot-TAT relay, which could result in increased resistance and overheating of the relay and consequent smoke in the cockpit; and to detect and correct oxidation of the FADEC electronic interface resistor modules, which could result in in-flight uncommanded engine power roll back to idle. This action is intended to address the identified unsafe condition.
2003-26-12: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737-600, 737-700, 737-800, 757-200, and 757-300 series airplanes, that requires replacing existing video distribution unit (VDU) connectors with new, improved connectors or new wire assemblies (jumpers), and performing related actions, as applicable. This action is necessary to prevent a short circuit in a VDU connector and consequent arcing and damage to wiring within the connector, which could result in damage to adjacent systems or structure and possible smoke or fire in the airplane cabin. This action is intended to address the identified unsafe condition.
2003-26-07: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-90-30 airplanes, that requires a one-time general visual inspection of the circuit breakers to determine if discrepant circuit breakers are installed, and corrective action if necessary. This action is necessary to prevent internal overheating and arcing of circuit breakers and airplane wiring due to long-term use and breakdown of internal components of the circuit breakers, which could result in smoke and fire in the flight compartment and main cabin. This action is intended to address the identified unsafe condition.
2003-25-12: This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Falcon 900 EX and Mystere-Falcon 900 series airplanes. This action requires installing an attachment support assembly for the fire extinguishing piping in the baggage compartment. For certain airplanes this action also requires modifying the liner panel of the baggage compartment. The actions specified by this AD are intended to prevent distortion of the fire extinguishing discharge nozzle as a result of the nozzle not being secure, which could result in poor diffusion of the fire extinguishing agent in the event of a fire in the baggage compartment. This action is intended to address the identified unsafe condition.
2003-25-09: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300 B4-600 series airplanes, Model A300 B4-600R series airplanes, Model A300 C4-605R Variant F airplanes, and Model A300 F4-605R airplanes. This AD requires modification of certain components of the 115 Volts Alternating Current (VAC) supply wiring and of the fuel gauging system. This action is necessary to prevent short circuits between 115 VAC wiring and certain fuel system electrical wire runs with subsequent overheating of the cadensicon sensor thermistor or fuel level sensor, which could be great enough to ignite fuel vapors in the fuel tank and cause an explosion. This action is intended to address the identified unsafe condition.
2003-25-11: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing airplane models, that requires a one-time inspection to identify all H-11 steel bolts installed in the latch fittings of the cargo doors, repetitive inspections for cracked or broken H-11 steel bolts, and follow-on and corrective actions if necessary. This amendment also requires eventual replacement of all H-11 steel bolts in the latch fittings of the cargo doors with Inconel bolts. This action is necessary to prevent broken bolts in the latch fittings, which could reduce the capability of the door latch to keep the door closed, and result in loss of a cargo door and consequent rapid depressurization of the airplane. This action is intended to address the identified unsafe condition.
2003-25-02: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777-200 and 777-300 series airplanes, that requires application of high-temperature sealant in designated areas of the strut aft dry bay. The actions specified by this AD are intended to prevent leakage of hydraulic fluid into the strut aft dry bay, where high temperatures associated with the adjacent primary exhaust nozzle may ignite the fluid, resulting in an uncontrolled fire in the strut aft dry bay. This action is intended to address the identified unsafe condition.
2003-25-10: This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that currently requires an inspection to detect chafing or damage of the electrical wires leading to the terminal strips in the center accessory compartment (CAC) area, and corrective actions if necessary. That AD also currently requires revising the wire connection stack up of certain cable terminals at the electrical power center bays in the CAC, and replacing certain terminal strips with new strips and removing applicable nameplates at electrical power center bays. This amendment requires additional actions for improving the terminal strips and revises the applicability of the existing AD to include additional airplanes. The actions specified by this AD are intended to prevent arcing and sparking damage to the power feeder cables, terminal strips, and adjacent structure, and consequent smoke and fire in the CAC. This action is intended toaddress the identified unsafe condition.
2003-25-07: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A319 and A320 series airplanes, that currently requires revising the airplane flight manual to specify procedures for landing under certain conditions of gusty winds and turbulence. This amendment requires replacement of both Elevator and Aileron Computers (ELACs) having L80 standards with new ELACs having L81 standards, which terminates the requirements of the existing AD. The actions specified by this AD are intended to prevent activation of the high angle-of-attack protection during final approach for landing, which could result in loss of ability to flare properly during landings. This action is intended to address the identified unsafe condition.
