2002-22-12: This amendment adopts a new airworthiness directive (AD), that is applicable to certain Titeflex Corporation high-pressure and medium- pressure hoses. This amendment requires inspecting certain Titeflex hoses for a date of manufacture, and if necessary, replacing the hose with a serviceable part. This amendment is prompted by reports of hoses that failed to meet the fire test requirements during laboratory testing. The actions specified by this AD are intended to prevent failure of a hose when exposed to fire.
2002-22-08: This amendment adopts a new airworthiness directive (AD) that is applicable to Hartzell Propeller Inc. model HD-E6C-3( ) propellers. This action requires replacement of the current design propeller blade thrust bearing with a new design propeller blade thrust bearing and visual and eddy current inspection (ECI) of propeller hubs for cracks. This amendment is prompted by reports of fractured thrust bearings observed during disassembly, one or more blades becoming jammed in position during operation, pitch change fork fractures causing loss of blade pitch control, and excessive vibration. The actions specified in this AD are intended to prevent loss of aircraft control due to loss of blade pitch control, inability to fully feather the propeller, hub fracture, and blade release.
2002-22-05: This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This action requires repetitive inspections to find cracks, fractures, or corrosion of each carriage spindle of the left and right outboard mid-flaps; and corrective action, if necessary. This action also provides for an optional action of overhaul or replacement of the carriage spindles, which would extend the repetitive inspection interval. This action is necessary to prevent severe flap asymmetry due to fractures of the carriage spindles on an outboard mid- flap, which could result in reduced control or loss of controllability of the airplane. This action is intended to address the identified unsafe condition.
2002-21-14: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 757-200, -200CB, and -300 series airplanes. This AD requires determining the part numbers of the master control valve on the pressure bottles that activate the off-wing escape slides, and performing corrective action if necessary. This action is necessary to prevent failure of an escape slide to deploy or inflate correctly, which could cause the slide to be unusable during an emergency evacuation and result in consequent injury to passengers or crewmembers. This action is intended to address the identified unsafe condition.
2002-21-08: This amendment adopts a new airworthiness directive (AD) that applies to certain Pilatus Aircraft Ltd. (Pilatus) Model PC-6 airplanes. This AD requires you to inspect the aileron assembly for correct configuration and modify as necessary. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. The actions specified by this AD are intended to correct improper aileron assembly configuration, which could result in failure of the aileron mass balance weight. Such failure could lead to loss of control of the airplane.
2002-20-09: This amendment adopts a new airworthiness directive (AD) that applies to certain Rockwell Collins, Inc. (Rockwell Collins) AFD-3010 adaptive flight display units that are installed on aircraft. This AD requires you to inspect the AFD-3010 unit to determine if it contains an MFP386 Application Specific Integrated Circuit (ASIC) device with a date code of 0128. This AD also requires you to have any AFD-3010 units with an MFP386 device with a date code of 0128 modified. This AD is the result of reports of a manufacturing defect. The actions specified by this AD are intended to prevent premature failure of the ASIC, which could result in the AFD-3010 unit displaying erroneous primary flight and engine parameter information. Such failure could lead to the pilot using incorrect information when making critical flight safety decisions.
2002-20-07: This amendment supersedes seven existing airworthiness directives (ADs), applicable to certain Boeing Model 737 series airplanes that, among other things, currently require replacing the main rudder power control unit (PCU) and PCU vernier control rod bolts; testing the main rudder PCU to detect certain discrepancies and to verify proper operation of the PCU; and revising the FAA-approved Airplane Flight Manual procedures to correct a jammed or restricted flight control condition. Instead, this amendment requires installation of a new rudder control system and changes to the adjacent systems to accommodate that new rudder control system. This amendment is prompted by FAA determinations that the existing system design architecture is unsafe due to inherent failure modes, including single-jam modes and certain latent failures or jams, which, when combined with a second failure or jam, could cause an uncommanded rudder hardover event and consequent loss of control of the airplane. Additionally, the current rudder operational procedure is not effective throughout the entire flight envelope. The actions specified by the proposed AD are intended to prevent the identified unsafe condition.
2002-20-02: This amendment adopts a new airworthiness directive (AD) for the specified Bell Helicopter Textron, A Division of Textron Canada (BHTC), model helicopters that requires removing sealant from the forward tooling hole in the right-hand upper fuel enclosure area. This amendment is prompted by the determination that fuel or water could accumulate in the right-hand upper fuel enclosure. The actions specified by this AD are intended to prevent accumulation of fuel in the right-hand upper fuel enclosure area, a fire, and a subsequent forced landing.
2002-15-51: This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2002-15-51, sent previously to all known U.S. owners and operators of the specified Sikorsky Aircraft Corporation (Sikorsky) helicopters by individual letters. This AD requires, before further flight, identifying and removing any main rotor blade (blade) that has been damaged by lightning and any blade with an unclear service history. This AD is prompted by the failure of a blade due to lightning strike damage. The actions specified by this AD are intended to prevent failure of a blade and subsequent loss of control of the helicopter.
2002-18-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-300, 747SP, and 747SR series airplanes, that requires one-time inspections for cracking in certain upper deck floor beams and follow-on actions. The actions specified by this AD are intended to find and fix cracking in certain upper deck floor beams. Such cracking could extend and sever floor beams adjacent to the body frame and result in rapid depressurization of the airplane. This action is intended to address the identified unsafe condition.
