Raytheon Aircraft Company Beech Models 45 (YT-34), A45 (T-34A, B-45), and D45 (T-34B) Airplanes
This document supersedes Airworthiness Directive (AD) 99-12- 02, which currently requires flight and operating limitations on Raytheon Aircraft Corporation (Raytheon) Beech Models 45 (YT-34), A45 (T-34A, B-45), and D45 (T-34B) airplanes. AD 99-12-02 resulted from a report of an in-flight separation of the right wing on a Raytheon Beech Model A45 (T-34A) airplane. The AD was issued as an interim action until the development of FAA-approved inspection procedures. Raytheon has developed procedures to inspect the wing spar assemblies of the above-referenced airplanes. This AD requires repetitive inspections of the wing spar assembly for cracks with replacement of any wing spar assembly found cracked (unless the spar assembly has a crack indication in the filler strip where the direction of the crack is toward the outside edge of the filler strip). This AD also includes a reporting requirement of the results of the initial inspection and maintains the flight and operating restrictions required by AD 99-12-02 until accomplishment of the initial inspection. The actions specified by this AD are intended to prevent wing spar failure caused by fatigue cracks in the wing spar assemblies and ensure the operational safety of the above-referenced airplanes.

Aerospatiale Model ATR42-200, -300, -320, and -500 Series Airplanes, and Model ATR72 Series Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR42-200, -300, -320, and - 500 series airplanes and Model ATR72 series airplanes, that requires temporarily revising the Airplane Flight Manual (AFM) to add tests of the engine fire protection system and conducting those tests prior to each flight. This amendment also requires replacement of defective engine fire handles with serviceable fire handles, which terminates the revision of the AFM and the repetitive tests of the engine fire protection system. These actions are necessary to prevent intermittent improper functioning of the engine fire handles, due to a machining defect of the control shaft bore guide, which could result in malfunction of the trigger (squib), and failure to activate one of the two engine fire extinguishers. This action is intended to address the identified unsafe condition.

Boeing Model 747 Series Airplanes
This amendment supersedes an existing airworthiness directive (AD), applicable to all Boeing Model 747 series airplanes, that currently requires repetitive inspections to detect cracking of the forward and aft inner chords and the splice fitting of the forward inner chord of the station 2598 bulkhead, and repair, if necessary. This amendment adds repetitive inspections of an expanded inspection area, which ends the inspections specified in the existing AD. This amendment also limits the applicability of the existing AD. This amendment is prompted by reports indicating that fatigue cracking was found on airplanes that had accumulated fewer total flight cycles than the threshold specified in the existing AD. The actions specified by this AD are intended to detect and correct fatigue cracking of the forward and aft inner chords, the frame support, and the splice fitting of the forward inner chord of the upper corner of the station 2598 bulkhead, which could result in reduced structural capability of the bulkhead and the inability of the structure to carry horizontal stabilizer flight loads.

This amendment supersedes an existing airworthiness directive (AD), applicable to all Boeing Model 767 series airplanes, that currently requires revising the Airplane Flight Manual (AFM) to include procedures that will ensure that the center tank fuel pumps are not operated with less than 1,000 pounds of fuel in the center tank. This amendment requires a further revision of the AFM to specify conditions for minimum fuel weight requirements and procedures for ground transfer of fuel for certain airplanes, repetitive inspections to detect discrepancies of the center tank override or override/jettison fuel pump, as applicable, and replacement of any discrepant pump with a new or serviceable pump. This amendment also requires that any override or override/jettison fuel pump without a diffuser be restored to a configuration that incorporates a diffuser. Additionally, this amendment requires installation of a new configuration center tank override or override/jettison fuel pump with a cast- in diffuser, which terminates the AFM revisions and repetitive inspections. The actions specified by this AD are intended to prevent ignition of fuel vapors due to the generation of sparks, to prevent a potential ignition source inside the fuel tank caused by steel-to-steel contact during dry fuel pump operation, and to ensure satisfactory fuel pump and fuel system operation.

Pratt and Whitney PW4000 Series Turbofan Engines
This amendment supersedes two airworthiness directives (AD's), 2000-22-01 and 2001-09-07, that both apply to Pratt and Whitney (PW) model PW4000 series turbofan engines. AD 2000-22-01 requires that operators limit the number of PW4000 engines equipped with the high pressure compressors (HPC) in the cutback stator (CBS) configuration to no more than one engine on each airplane, and prohibits the installation of engines with HPC modules in the CBS configuration after the effective date of that AD. AD 2001-09-07 requires that operators limit the number of engines with potentially reduced stability to no more than one engine on each airplane, and remove those engines before exceeding certain cyclic limits. Reports of HPC surges in PW4000 engines that have the HPC in the CBS configuration prompted those AD's. This Amendment will limit the number of PW4000 engines with potentially reduced stability on each airplane by applying rules based on airplane and engine configuration, and require that engines that exceed HPC compressor cyclic limits based on cycles-since-overhaul (CSO) are removed from service. This AD will also limit the number of engines with HPC CBS configuration to one on each airplane, and will establish a minimum rebuild standard for engines that are returned to service. This Amendment is prompted by further analyses of compressor surges in PW4000 engines. The actions specified by this AD are intended to prevent multiple-engine power losses due to high pressure compressor (HPC) surge and to reduce the rate of single-engine surge events.

Rockwell Collins, Inc. CTL-92 Transponder Control Panels
This amendment adopts a new airworthiness directive (AD) that applies to certain Rockwell Collins, Inc. (Rockwell Collins) CTL-92 transponder control panels that are installed on aircraft. This AD requires you to modify the altitude encoder inputs of the CTL-92 transponder control panels. This AD is the result of reports of noise generation within the CTL-92 transponder control panels that the transponder can interpret and transmit as a random altitude. Air traffic control (ATC) and traffic alert and collision avoidance system (TCAS)-equipped aircraft can then interpret these erroneous random altitudes as valid altitudes. The actions specified by this AD are intended to prevent such erroneous altitude interpretations, which could result in reduced vertical separation or unsafe TCAS resolution advisories.
