2004-16-07: The FAA is adopting a new airworthiness directive (AD) for GE CT7-2D1 turboshaft engines. This AD requires replacing certain turbine stage 2 aft cooling plates, part number (P/N) 6064T0P02. This AD results from an uncontained failure of a turbine stage 2 aft cooling plate in a GE CT7 turboprop engine. We are issuing this AD to prevent a similar uncontained failure of turbine stage 2 aft cooling plates in GE CT7-2D1 turboshaft engines.
2004-15-16: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A310 series airplanes, that requires modification of certain wires in the right-hand wing. This action is necessary to ensure that fuel quantity indication wires are properly separated from wires carrying 115-volt alternating current (AC). Improper separation of such wires, in the event of wire damage, could lead to a short circuit and a possible ignition source, which could result in a fire in the airplane. This action is intended to address the identified unsafe condition.
2004-15-19: The FAA adopts a new airworthiness directive (AD) for certain the New Piper Aircraft, Inc. (Piper) Model PA-46-500TP airplanes. This AD requires you to inspect (one-time) for the existence of any protective cover over the percussion caps or silicon tube installed over the end of the trigger mechanism pin of the oxygen generators, and remove any protective cover or silicon tube found. This AD is the result of reports of the above conditions found on the affected airplanes. We are issuing this AD to detect and remove any protective cover over the percussion cap, or any silicon tube over the end of the trigger mechanism pin, which could result in failure of the emergency oxygen system. This failure could lead to the crew and passengers not being able to get oxygen in an emergency situation.
2004-15-13: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and Model MD-88 airplanes, that requires replacement of certain freeze protection ribbon heaters in the lavatory water supply system, and flushing, cleaning, and sterilizing the potable water system; disconnecting, coiling, and stowing the wiring of the freeze protection ribbon heater; or removal of freeze protection heaters. This action is necessary to prevent failure of freeze protection ribbon heaters, which could result in the charring, scorching, smoking, and shorting out of freeze protection ribbon heaters in the lavatory water supply system. This condition, if not corrected, could also result in electrical arcing of freeze protection ribbon heaters, leading to fire and damage to water lines and components under the lavatory sink. This action is intended to address the identified unsafe condition.
2004-15-09: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model DHC-8-101, -102, -103, -106, - 201, -202, -301, -311, and -315 airplanes. This amendment requires an inspection of the fuel tube assembly of the auxiliary power unit (APU) for clearance from adjacent components; and an inspection of the fuel tube assembly and the bleed air duct shroud for discrepancies (insufficient clearance, nicks, dents, chafing, or other damage); and related investigative and corrective actions if necessary. This amendment also requires relocation of certain support clamps on the APU fuel tube assembly. This action is necessary to prevent a fuel leak caused by chafing of the APU fuel tube assembly, which could result in fire in the center wing area. This action is intended to address the identified unsafe condition.
2004-15-05: This amendment adopts a new airworthiness directive (AD), applicable to certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series airplanes, that requires replacing the existing bellows inlet duct of the auxiliary power unit (APU) system with a new, improved rectangular metallic bellows inlet duct. This action is necessary to prevent air from the APU bay being ingested into the flight deck and passenger cabin resulting in poor air quality and, if the air is contaminated, possible incapacitation of the flightcrew and passengers. This action is intended to address the identified unsafe condition.
2004-15-01: The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon) Model 390 airplanes. This AD requires you to inspect the hydraulic tube/hose assemblies, the engine fuel feed tube assemblies, and the engine wire harnesses for proper clearance and damage (as applicable). If improper clearance or damage is found on any assembly, you must replace and/or modify the affected assembly. This AD is the result of reports of loss of the hydraulic system functions during different operations caused by improper clearance between certain components. This resulted in damage to the tubing in the hydraulic system assemblies. Analysis shows a similar condition on the engine fuel feed assemblies. We are issuing this AD to detect, correct, and prevent such damage or improper clearance in the affected areas, which could result in failure of one or more of these systems. These failures could lead to loss of hydraulic system operations, engine shutdown, and false readings for fuel pressure, oil pressure, and other oil indications. These conditions could consequently result in reduced or loss of control of the airplane.
2004-14-24: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120 series airplanes, that currently requires measuring the gap between the bellcrank and the body of the rotary variable inductive transducers (RVITs) of the aileron and elevator, performing corrective action if necessary, and torquing the bolt that attaches the bellcrank to the RVIT shaft. This amendment requires replacing the aileron and elevator RVIT bellcranks with new, improved bellcranks. The actions specified by this AD are intended to prevent restricted movement of the aileron or elevator, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
2004-14-08: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300-600 and A310 series airplanes, that requires modification of the attachment system of the insulation blankets of the forward cargo compartment and related corrective action. This action is necessary to prevent failure of the attachment system of the cargo insulation blankets, which could result in detachment and consequent tearing of the blankets. Such tearing could result in blanket pieces being ingested into and jamming the forward outflow valve of the pressure regulation subsystem, which could lead to cabin depressurization and adversely affect continued safe flight of the airplane. This action is intended to address the identified unsafe condition.
2004-14-21: The FAA adopts a new airworthiness directive (AD) for all Stemme GmbH & Co. Models S10, S10-V, and S10-VT sailplanes. This AD requires you to remove the drive shaft assembly and ship it to the service department of Stemme GmbH & Co. The engine is mounted behind the two side-by-side seats. The engine combined with the carbon fiber drive shaft turn the centrifugally extended propeller. After an initial visual inspection, the service department will perform an operational check to determine whether the drive shaft can be further used or must be replaced. Once corrective action is identified, a drive shaft will be shipped to you for installation. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect and correct incorrectly glued drive shafts, which could result in drive shaft failure. During self-takeoff or critical periods of landing, failure of the drive shaft could leadto loss of control of the sailplane.
