Airworthiness Directives; BAE Systems (Operations) Limited Model BAe 146 Series Airplanes

Wed, Mar 10 2004 11:00:00 GMT

This amendment adopts a new airworthiness directive (AD), applicable to all BAE Systems (Operations) Limited Model BAe 146 series airplanes, that requires repetitive general visual inspections of the inside of the condenser regenerative air ducts, air cycle machine turbine outlet, and the jet pump ducts on each air conditioning pack to detect oil and/or oil breakdown products leaking from the engine(s) or auxiliary power unit (APU). This AD also requires further inspections and replacement of any affected engine, APU, or component with a serviceable part, if necessary. This action is necessary to prevent impairment of the operational skills and abilities of the flightcrew caused by oil or oil breakdown products in the cabin air, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.

Airworthiness Directives; Boeing Model 707 and 720 Series Airplanes

Wed, Mar 10 2004 11:00:00 GMT

This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 707 and 720 series airplanes, that requires inspection of the bolt forward of the wing front spar upper chord on the overwing support fittings of the inboard and outboard nacelle struts to verify that BACB30US type bolts are installed. If any other type of bolt is found, this amendment requires replacement with a new BACB30US type bolt. This action is necessary to prevent separation of the engine from the airplane due to stress corrosion cracking and consequent fracturing of the bolts. This action is intended to address the identified unsafe condition.

Airworthiness Directives; Bombardier Model DHC-8-401 and -402 Airplanes

Wed, Mar 10 2004 11:00:00 GMT

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Bombardier Model DHC8401 and 402 airplanes. This action requires a records review to determine the repair/ modification status of the airplane, and followon and corrective actions as necessary. This action is necessary to prevent cracks in the lower fuselage skin due to fatigue damage in the vicinity of the Number 2 VHF antenna, which could result in rapid decompression of the airplane. This action is intended to address the identified unsafe condition.

Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

Wed, Mar 10 2004 11:00:00 GMT

This amendment adopts a new airworthiness directive (AD) that is applicable to all Bombardier Model CL6002B19 (Regional Jet Series 100 & 440) airplanes. This action requires repetitive inspections of the left and right engine throttle control gearboxes for wear, and corrective action if necessary. This action is necessary to prevent excessive wear of the gearboxes and subsequent movement or jamming of the engine throttle; movement of the throttle towards the idle position brings it close to the fuel shutoff switch, which could result in an inflight engine shutdown. This action is intended to address the identified unsafe condition.

Airworthiness Directives; Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 Airplanes

Wed, Mar 10 2004 11:00:00 GMT

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Bombardier airplanes as listed above. This action requires lubrication of the flap actuators, repetitive measurements (``checks'') of the backlash of the flap actuators, determination of the next backlash measurement interval, and replacement of discrepant actuators with new or overhauled actuators if necessary. This action is necessary to prevent the mechanical disconnection of a flap actuator, which, if followed by failure of the flap panel's second actuator due to increased loading, could result in flap asymmetry and consequent loss of controllability of the airplane. This action is intended to address the identified unsafe condition.

Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135 and -145 Series Airplanes

Wed, Mar 10 2004 11:00:00 GMT

This amendment supersedes an existing airworthiness directive (AD), applicable to all Model EMB135 and 145 series airplanes, that currently requires repetitive inspections to detect discrepancies of both verticaltohorizontal stabilizer bonding jumpers and the connecting support structure, and corrective action if necessary. This amendment requires modification of the bonding jumpers, including the installation of a protective cover to the elevator control cables, which terminates the requirements of the existing AD. The actions specified by this AD are intended to prevent damaged or severed bonding jumpers, which, in the event of a lightning strike, could result in severed elevator control cables and consequent reduced elevator control capability and reduced controllability of the airplane. This action is intended to address the identified unsafe condition.

Airworthiness Directives; Eurocopter France Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D,

Wed, Mar 10 2004 11:00:00 GMT

This amendment supersedes an existing airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters that currently requires certain inspections of the main rotor swashplate bearing (bearing) and plugging the nonrotating swashplate vent holes and barrel nut orifices. This amendment eliminates most of those AD actions, which are now included in the Airworthiness Limitations section of the maintenance manual, but retains the requirements for the inspections and lubrication of the main rotor swashplate. This amendment also clarifies that repetitive maintenance of the main rotor swashplate and bearing is required at intervals not to exceed 100 hours timeinservice (TIS). This amendment is prompted by the need to clarify the AD wording to avoid any misinterpretation of the required interval for inspecting and lubricating the main rotor swashplate and bearing. The actions specified by this AD are intended to prevent failure of the bearing and subsequent loss of control of the

Airworthiness Directives; Rolls-Royce Deutschland (RRD) (Formerly Rolls-Royce, plc) TAY 611-8, TAY 620-15, TAY

Wed, Mar 10 2004 11:00:00 GMT

The FAA is adopting a new airworthiness directive (AD) for certain RRD TAY 6118, TAY 62015, TAY 65015, and TAY 65154 series turbofan engines with iceimpact panels installed in the low pressure (LP) compressor case. This AD requires
[[Page 11306]]
inspecting all iceimpact panels and fillers in the LP compressor case for certain conditions, and if necessary, replacing any iceimpact panels and fillers that have those conditions. This AD results from two reports of iceimpact panels that released during flight, one of which resulted in reduction of power in both engines. We are issuing this AD to prevent release of iceimpact panels due to improper bonding that can result in loss of thrust in both engines.

Airworthiness Directives; Cessna Aircraft Company Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H Airplanes

Wed, Mar 10 2004 11:00:00 GMT

The FAA proposes to supersede Airworthiness Directive (AD) 20032413, which applies to certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H airplanes that are equipped with a certain Honeywell KAP 140 autopilot computer system installed on the center instrument control panel near the throttle. AD 20032413 currently requires you to install an update to the operating software of certain KAP 140 autopilot computer system, change the unit's part number, and change the software modification identification tab. This proposed AD is the result of the FAA inadvertently omitting four affected Honeywell KAP 140 autopilot computer system part numbers and an affected airplane serial number from the applicability section of AD 20032413. This proposed AD retains the actions required in AD 20032413, corrects the applicability section, and incorporates a revised installation bulletin issued by Honeywell.
