2004-05-23: This amendment supersedes an existing airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters that currently requires certain inspections of the main rotor swashplate bearing (bearing) and plugging the nonrotating swashplate vent holes and barrel nut orifices. This amendment eliminates most of those AD actions, which are now included in the Airworthiness Limitations section of the maintenance manual, but retains the requirements for the inspections and lubrication of the main rotor swashplate. This amendment also clarifies that repetitive maintenance of the main rotor swashplate and bearing is required at intervals not to exceed 100 hours time-in-service (TIS). This amendment is prompted by the need to clarify the AD wording to avoid any misinterpretation of the required interval for inspecting and lubricating the main rotor swashplate and bearing. The actions specified by this AD are intended to prevent failure of the bearing and subsequent loss of control of the helicopter.
2004-05-16: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-200 and -300 series airplanes, that requires repetitive inspections of the aft pressure bulkhead web, and corrective action, if necessary. This action is necessary to detect and correct fatigue cracks in the aft pressure bulkhead web, which could result in uncontrolled rapid decompression. This action is intended to address the identified unsafe condition.
2004-05-19: This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 737-600, -700, -700C, -800, and -900 series airplanes. This action requires an inspection of the rear spar attach pins and front spar attach bolts that attach the horizontal stabilizers to the horizontal stabilizer center section for damage; and follow-on or corrective actions, as applicable. This action is necessary to detect and correct damaged rear spar attach pins or front spar attach bolts, which may lead to failure of the bolts or pins, and consequent loss of the stabilizer and loss of controllability of the airplane. This action is intended to address the identified unsafe condition.
2004-05-05: This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-2C, B4-103, and B4-203 series airplanes, that currently requires a one-time inspection of the space between the fuel quantity indication (FQI) probes and any adjacent structures for minimum clearance, and corrective action if necessary. This amendment expands the applicability in the existing AD and requires the subject one-time inspection on additional airplanes. The actions specified by this AD are intended to prevent the possibility of electrical arcing to the fuel tank if the airplane should be struck by lightning. Such arcing could create a potential ignition source within the fuel tank and an increased risk of a fuel tank explosion and fire. This action is intended to address the identified unsafe condition.
2004-05-09: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas airplane models, that requires a one-time inspection for chafing of wiring in the left-hand tunnel area of the forward cargo compartment, repair if necessary, and coiling and stowing of excess wiring. This action is necessary to prevent wire chafing and subsequent shorting to structure in the forward cargo compartment, which could result in smoke or fire in the airplane. This action is intended to address the identified unsafe condition.
2003-22-07 R1: The FAA is revising Airworthiness Directive (AD) 2003-22-07, which applies to all Mitsubishi Heavy Industries, Ltd. (Mitsubishi) MU- 2B series airplanes. AD 2003-22-07 requires incorporating information into the Limitations Section of the Airplane Flight Manual (AFM) that requires pilot training before flight into known or forecast icing conditions after a certain date. AD 2003-22-07 resulted from the development of a new training video that includes information that is critical to safety of the MU-2B series airplanes. This AD revision is the result of the FAA incorrectly stating in the actions required by AD 2003-22-07 that on or before June 15, 2004 (the effective date of AD 2003-22-07), no person may serve as pilot-in-command (PIC) of a MU-2B series airplane in a flight into known or forecast icing conditions, unless the PIC has received the required training. Consequently, this AD will correct the actions required in AD 2003-22-07 to require those actions on or after June15, 2004. We are issuing this AD to ensure that the Icing Awareness Training (IAT) requirement continues after June 15, 2004, in order to decrease the chance of icing-related incidents or accidents of the MU-2B series airplanes due to pilot error.
2004-04-11: This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Mystere-Falcon 50 series airplanes, that requires applying PR (fuel tank sealant) and installing PR patches over the internal side panel recesses of the left-hand and right-hand feeder tanks at certain frames and stringers. This action is necessary to prevent possible fuel ignition in the event of a lightning strike and consequent uncontained rupture of the fuel tank(s). This action is intended to address the identified unsafe condition.
2004-01-51: 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.
2004-04-04: 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.
2004-03-36: This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires a one-time inspection of certain engine control cables to determine the batch number on the end fitting, and replacement of affected cables with new cables. This action is necessary to prevent failure of defective engine control cables, which could result in loss of the engine controls, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
