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.
2002-07-02: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Israel Aircraft Industries, Ltd., Model Galaxy airplanes and Model Gulfstream 200 series airplanes. This action requires repetitive inspections of the main landing gear (MLG) actuators for leakage of hydraulic fluid, a one-time inspection of the MLG actuators for internal abrasions or scratches, and replacement of the MLG actuator with a new or serviceable or new, improved actuator, if necessary. This action also provides an optional terminating action for the repetitive inspections. This action is necessary to prevent failure of an MLG actuator to fully extend and retract, which could prevent proper engagement of the downlock mechanism and result in collapse of the MLG during landing. This action is intended to address the identified unsafe condition.
2002-06-16: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-300 airplanes. This action requires removing each sidewall-mounted reading light in the attendant crew rest compartment, installing cover plates in place of the existing reading lights, removing each reading light switch, and installing a new reading light in place of the existing light switch. This action is necessary to prevent contact between the occupant of the attendant crew rest compartment and the sidewall-mounted reading lights, which could result in possible injury to the occupant; and to prevent contact between various flammable materials and the sidewall-mounted reading lights, which could cause charring or melting of the heated material, and consequent emission of toxic or noxious gases. This action is intended to address the identified unsafe condition.
2002-06-12: This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Mystere-Falcon 50 series airplanes, that requires repetitive tests of double-skin feeder tanks for fuel leaks, and corrective actions, if necessary. It also requires modification of seals in the feeder tanks, which terminates the repetitive leak tests. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign airworthiness authority. The actions specified by this AD are intended to prevent fuel leaks from the feeder tanks, which could result in fuel vapors in the cabin that could come into contact with ignition sources. The actions are intended to address the identified unsafe condition.
2002-06-06: This amendment adopts a new airworthiness directive (AD) that applies to certain Rockwell Collins TDR-94 and TDR-94D Mode S transponders that derive altitude information from a Gillham (gray code) encoded pressure altitude source and are installed on airplanes. This AD requires you to have the unit modified to prevent erroneous altitude reporting. This AD is the result of reports that erroneous altitude resolutions could occur when the affected transponders are utilized in areas with other airplanes equipped with certain aircraft collision avoidance system (ACAS) or traffic alert and collision avoidance system (TCAS) configurations. The actions specified by this AD are intended to prevent these erroneous altitude resolutions from causing a reduction in the intended ACAS or TCAS Change 7 separation margins. Such a condition could result in air traffic control or the pilot making flight decisions that put the airplane in unsafe flight conditions.
2002-06-05: This amendment adopts a new airworthiness directive (AD), applicable to various transport category airplanes equipped with certain Mode C air traffic control (ATC) transponders manufactured by Rockwell Collins, Inc. This amendment requires testing each transponder; replacing certain parts in any transponder that fails the initial test with new parts and performing additional test(s); and making repairs, as necessary, so that the transponder passes the test. This amendment is prompted by reports that indicate that the equipment used to conduct earlier tests of certain transponders did not detect certain malfunctions. An airplane equipped with such malfunctioning transponders could transmit inaccurate data concerning its altitude to a nearby airplane equipped with the traffic alert and collision avoidance system (TCAS II), causing the TCAS II to issue an erroneous resolution advisory to the pilot. The actions specified by this AD are intended to prevent transmission of inaccurate data concerning altitude from one airplane to another, which could cause the pilot receiving the data to change course, either ascending or descending, and possibly lead to a mid-air collision or near mid-air collision.
2002-06-02: This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 747 series airplanes. This action requires repetitive inspections for cracking of the upper skin of the horizontal stabilizer center section and the rear spar upper chord, and repair, if necessary. This action is necessary to find and fix such cracking, which could lead to reduced structural capability of the horizontal stabilizer center section, and result in loss of controllability of the airplane. This action is intended to address the identified unsafe condition.
2002-05-04: This amendment supersedes Airworthiness Directive (AD) 77-15- 06, which applies to all SOCATA--Groupe AEROSPATIALE (Socata) Models MS 892A-150, MS 892E-150, MS 893A, MS 893E, Rallye 150T, and Rallye 150ST airplanes. AD 77-15-06 currently requires you to repetitively inspect the engine mount assembly for cracks, repair any cracks found, and modify the brackets on airplanes with right angle engine mounts. This AD is the result of the French airworthiness authority's determination that updated service information and additional aircraft should be added to the applicability of AD 77-15-06. This AD retains the inspection and repair requirements of the current AD and adds the information communicated by the French airworthiness authority. The actions specified by this AD are intended to detect and correct cracks in the engine mount assembly. Such a condition could cause the engine mount assembly to fail, which could result in loss of control of the airplane.
2002-04-03: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Fokker Model F27 Mark 050 series airplanes. This action requires reinforcement of the structural provisions for the Global Positioning System (GPS) antenna by replacement of existing fasteners with new fasteners, and installation of conical washers and a doubler plate at stringer 26, as applicable. This action is necessary to prevent cracking of the structure of the fuselage pressure vessel in the area of the GPS antenna, leading to reduced structural integrity of the fuselage pressure vessel, which could result in depressurization of the airplane. This action is intended to address the identified unsafe condition.
2002-03-14: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B19 series airplanes, that requires repetitive inspections for cracking of the left and right lower wing planks, and repair, if necessary. The actions specified by this AD are intended to find and fix such cracking, which could result in reduced structural integrity of the wing. This action is intended to address the identified unsafe condition.
