2002-09-11: This amendment supersedes Airworthiness Directive (AD) 2001-05-03, which applies to certain SOCATA-Groupe AEROSPATIALE (Socata) Model TBM 700 airplanes. AD 2001-05-03 currently requires you to apply Loctite on attaching bolt/screw threads of inboard, central, and outboard carriages; increase tightening torques of associated hardware; and replace central carriage attaching bolts. The French airworthiness authority has determined that certain service information referenced in AD 2001-05-03 be removed and additional inspection of the flap carriage attaching bolts, screws, and barrel nut be included. Therefore, this AD will retain the requirements of the current AD and will add the information communicated by the French airworthiness authority. The actions specified by this AD are intended to prevent the flap attaching bolts/screws from becoming loose and separating from the airplane, which could cause rough or irregular control. Such rough or irregular control could lead to the loss of control of the airplane.
2002-09-05: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 series airplanes, that requires a one-time inspection of the fuel-level sensing wires in the center fuel tank for damage and for clearance from the adjacent structure; and corrective action, if necessary. The actions specified by this AD are intended to detect and correct inadequate clearance between the fuel-level sensing wires in the center fuel tank and adjacent structures, which could lead to chafing of the wires, resulting in electrical arcing between the fuel-level sensing wires and the center fuel tank and a consequent fire or explosion in the center fuel tank. This action is intended to address the identified unsafe condition.
2002-08-51: This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2002-08-51 that was sent previously to all known U.S. owners and operators of Airbus Model A300 B2 and B4 series airplanes equipped with General Electric CF6-50 engines by individual notices. This AD requires deactivating both thrust reversers and revising the airplane flight manual (AFM) to require performance penalties during certain takeoff conditions to ensure that safe and appropriate performance is achieved for airplanes on which both thrust reversers have been deactivated. This action is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent uncommanded in-flight deployment of a thrust reverser, which could result in reduced controllability of the airplane.
2002-08-12: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A330 and A340 series airplanes. This action requires an inspection of the parking brake operated valve (PBOV) of the main landing gear to identify the part and serial numbers, and follow-on actions if necessary. This action provides for optional terminating action for the requirements of this AD. This action is necessary to prevent leakage of the PBOV and consequent failure of the "blue" hydraulic system, which could affect elements of the hydraulics for flaps, stabilizer, certain spoilers, elevator, rudder, and aileron. This action is intended to address the identified unsafe condition.
2002-08-14: This amendment adopts a new airworthiness directive (AD) that is applicable to all Airbus Model A300 B2 and B4; A300 B4-600, B4-600R, and F4-600R (collectively called A300-600); and A310 series airplanes. This action requires identification of the part number and serial number of the parking brake operated valve (PBOV); and, if necessary, inspection of the PBOV, including a functional check of the PBOV, and follow-on and corrective actions. This action also provides for optional terminating action for the requirements of this AD. This action is necessary to prevent loss of the yellow hydraulic system, which provides all the hydraulics for certain spoilers; elements of the hydraulics for flaps, stabilizer, pitch and yaw feel systems, pitch and yaw autopilot, and yaw damper; and elevator, rudder, and aileron. This action is intended to address the identified unsafe condition.
2002-08-15: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires an inspection of the tripod strut assembly of the inboard support of the leading edge slat of the wing for a preload condition, and follow-on actions. For certain airplanes, this AD also requires inspection and replacement of the existing tripod struts with new, adjustable struts, if necessary. This action is necessary to prevent damage to the tripod strut assembly due to a preload condition, which could result in loss of control of the inboard leading edge slat or separation of the slat from the airplane, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
2002-06-53: This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2002-06-53 that was sent previously to all known U.S. owners and operators of Airbus Model A319, A320, A321, A330, and A340 series airplanes equipped with certain Thales Avionics Digital Distance and Radio Magnetic Indicators (DDRMIs) by individual notices. This AD requires deactivation of certain Thales Avionics DDRMIs. This action is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the DDRMI, which could cause the loss of data from the affected computers to other systems and degradation or total failure of the computers, leading to reduced ability to control the airplane in adverse conditions.
2002-08-06: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 777-200 and -300 series airplanes. This action requires a one-time torque check (inspection) of the bolts that attach the pivot fittings to the horizontal stabilizer through the upper and lower titanium straps, to determine if the bolts are adequately torqued, and follow-on actions. This action is necessary to prevent failure of the pivot fittings, which could result in loss of control of the horizontal stabilizer and consequent loss of control of the airplane. This action is intended to address the identified unsafe condition.
2001-24-51: This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2001-24-51, which was sent previously to all known U.S. owners and operators of MD Helicopters, Inc. (MDHI) Model 600N helicopters by individual letters. This AD requires, within 5 hours time-in-service (TIS), inspecting both upper tailboom attachments, nutplates and both angles for a crack or thread damage and repairing or replacing any cracked or damaged part before further flight. Also, this AD requires replacing the upper right-hand (RH) tailboom attachment bolt (bolt) with a new bolt, and if the upper RH bolt is broken, replacing the three remaining bolts with airworthy bolts before further flight. Adding a washer to each bolt and modifying both upper access covers are also required. Thereafter, at specified intervals, inspecting the upper tailboom attachments and repairing or replacing any cracked part before further flight is required. This AD is prompted by the discoveryof a cracked bolt on a helicopter. The actions specified by this AD are intended to prevent failure of a tailboom attachment, loss of the tailboom, and subsequent loss of control of the helicopter.
2002-07-10: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737-200, -200C, -300, -400, and -500 series airplanes, that requires replacement of certain repairs in certain fuselage lap joints with improved repairs. This amendment also requires a high frequency eddy current inspection to find cracking of the repairs of the lower skin at the lower row of fasteners in the lap joints of the fuselage, and repair of any cracking found. This action is necessary to find and fix premature cracking of certain lap joint repairs, which could result in rapid decompression of the airplane. This action is intended to address the identified unsafe condition.
