2005-23-18: The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F27 Mark 050 airplanes. This AD requires a one-time inspection of the bleed air supply ducts to determine if blanking plugs are present and a one-time inspection of the entire area of the engine nacelle for heat damage; and corrective actions if necessary. This AD also requires replacement of the blanking plugs with clamping devices. This AD results from heat damage in areas adjacent to the bleed air supply duct assembly. We are issuing this AD to prevent rupture of the bleed air supply duct, which could lead to hot bleed air leaking into the engine controls area and result in heat damage to control cables, electrical wiring, hydraulic components, and fuel lines, and consequent fire.
2005-23-02: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319-100 series airplanes, Model A320-111 airplanes, Model A320-200 series airplanes, and Model A321-100 series airplanes equipped with any additional center tank (ACT). This AD requires identifying the part number of the ACT and, for certain ACTs, replacing the outer ACT manhole cover and seal. This AD results from reports of an ACT fuel transfer failure due to air leakage around the seal of the outer manhole covers of the ACTs. We are issuing this AD to prevent this leakage, which could result in fuel or fuel vapor leaking into the cargo compartment, and consequent increased risk of a fire in the cargo compartment.
2005-23-14: The FAA is adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 airplanes. This AD requires repetitively replacing the low-stage check valve and associated seals of the right-hand engine bleed system.

We are issuing this AD to prevent failure of the low-stage check valve, which could result in an engine shutting down during flight.
2005-23-13: The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-135 airplanes, and Model EMB-145, -145ER, - 145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This AD requires modification of the logic of the steering system of the nose landing gear (NLG) wheel. This AD results from reports of the loss of directional control of the airplane on the ground after an internal failure of the NLG wheel steering system. We are issuing this AD to prevent failure of the NLG wheel steering system, which could result in reduced controllability of the airplane.
2005-23-07: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 727 airplanes. This AD requires revising the Limitations section of the airplane flight manual to prohibit resetting a tripped circuit breaker for a fuel pump. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prohibit the resetting of a tripped circuit breaker for a fuel pump, which could allow an electrical fault to override the protective features of the circuit breaker, and could result in sparks inside the fuel tank, ignition of fuel vapors, and consequent fire or explosion.
2005-22-13: The FAA adopts a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Models PC-12 and PC-12/45 airplanes. This AD requires you to inspect the left and right main landing gear (MLG) assemblies for any part number (P/N) 532.10.12.077 or FAA- approved equivalent part number bolts that do not have white primed and painted heads; and replace any bolt found with new P/N 532.10.12.077F or FAA-approved equivalent part number bolts in all MLG assemblies. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Switzerland. We are issuing this AD to detect and correct any P/N 532.10.12.077 or FAA- approved equivalent part number bolts that do not have white primed and painted heads, which could result in corrosion of the bolt and consequent failure of the bolt. This failure could lead to MLG collapse during airplane landing and take-off operations with consequent loss of airplane control.
2005-22-09: The FAA is adopting a new airworthiness directive (AD) for all Aerospatiale Model ATR42 and ATR72 airplanes. This AD requires a one- time inspection to determine the part number or markings of the fuel quality indicator (FQI) and replacement of any FQI having an incorrect part number. This AD results from a report that an FQI having an incorrect part number was installed on a Model ATR72 airplane. We are issuing this AD to ensure that a correct FQI is installed. An incorrect FQI could result in fuel starvation to the engine and consequent engine shutdown during flight.
2005-22-05: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A320-111, -211, -212, and -231 airplanes. This AD requires, for certain airplanes, modifying the cables and access holes to the inner tank fuel pumps; and, for certain other airplanes, inspecting the fuel pump access holes and modifying the access holes, if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent chafing of the fuel pump cables, which could result in electrical arcing and possible ignition of fuel vapors and consequent explosion of the fuel tank.
2005-22-06: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747- 200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. This AD requires doing a one-time high-frequency eddy current inspection and repetitive detailed inspections for cracks in the frame web of main entry door number 1; and repairing the door frame web if necessary. This AD also provides for optional terminating action for the repetitive inspections. This AD is prompted by reports of cracking at the upper aft corner of the cutout for main entry door number 1 in the station 488 frame web. We are issuing this AD to detect and correct cracks in the frame web. These cracks could cause the frame to break and lead to rapid decompression of the airplane.
2005-21-05: The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) (formerly Rolls- Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH) models BR700- 710A1-10 and BR700-710A2-20 turbofan engines. That AD currently requires initial and repetitive visual and ultrasonic inspections of fan discs, part numbers (P/Ns) BRR18803, BRR19248, and BRR20791 for cracks, and if necessary, replacement with serviceable parts. This ad requires those same inspections for discs having old design P/N fan blades installed, and, extends the inspection interval for fan discs having new design P/N fan blades installed. Also, this AD adds as optional terminating action to the inspections, installation of certain P/N new fan discs, certain P/N new fan blades, and engine fan speed (N1) Keep Out Zone software. This AD results from a revised RRD service bulletin (SB) that introduces relaxed inspection intervals for certain P/N combinations of fan discs and fanblades, and introduces improved design fan discs and fan blades. DATES: This AD becomes effective November 25, 2005. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of November 25, 2005. The Director of the Federal Register previously approved the incorporation by reference of certain other publications as listed in the regulations as of April 28, 2003 (68 FR 17727, April 11, 2003).
2005-21-02: This amendment supersedes an existing airworthiness directive (AD) for the MD Helicopters, Inc. (MDHI) Model 369A, H, HE, HM, HS, D, and E helicopters with a certain part-numbered main rotor blade (blade) and modified with a Helicopter Technology Company, LLC (HTC), Supplemental Type Certificate (STC) No. SR09172RC, SR09074RC, or SR09184RC. That AD currently requires recording on the component history card or equivalent record (record) each torque event (TE) on each blade, inspecting both surfaces of the blade, and replacing any cracked blade with an airworthy blade. Also, that AD establishes life limits for certain part-numbered blades. This amendment revises the model applicability, adds MDHI part-numbered blades, removes any reference to the life limits of the blades, changes the requirements for inspecting the blades, and revises the STC applicability. This amendment also provides that compliance with portions of certain documents constitutes alternative methods of compliance with portions of this AD, contains editorial changes for clarification, and makes some corrections. This amendment is prompted by additional reports of cracked blades and by the comments received in response to AD 2003-24- 01. The actions specified in this AD are intended to detect fatigue cracking of the blade to prevent blade failure and subsequent loss of control of the helicopter.
2005-20-14: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-620, A310-304, A310-324, and A310-325 airplanes. This AD requires installing fused adaptors between the external wiring harness and the in-tank wiring at the connectors on the fuel tank wall of the auxiliary center tank (ACT). This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an ignition source in the ACT, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
2005-20-20: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-301, -321, -322, -341, and -342 airplanes; and Model A340-200 and A340-300 series airplanes. This AD requires installing lockplates on the main landing gear (MLG) and center landing gear (CLG) wheel assemblies, as applicable, to keep the tie bolts in position in the wheel assembly in the event of a tie bolt failure. This AD results from reports of tie bolts that were broken or missing from the MLG wheel assembly; in some cases the wheels have ruptured and caused damage to other equipment in the adjacent area. We are issuing this AD to prevent damage to the wheel assembly and equipment in the area adjacent to the MLG and CLG, which could result in a decrease in braking function and possible runway over-run.
2005-20-17: The FAA is adopting a new airworthiness directive (AD) for certain Airbus airplane models, as specified above. This AD requires modifying the parking brake system to automatically restore the normal brake if the parking brake pressure decreases below a certain threshold. This AD results from a report of failure of the parking brake while the airplane was on the holding point of the runway before takeoff, leading to a runway departure. We are issuing this AD to ensure normal braking is available to prevent possible runway departure in the event of failure of the parking brake.
2005-20-18: The FAA is superseding two existing airworthiness directives (AD), which apply to certain Boeing transport category airplanes. One AD currently requires doing certain inspections to detect cracks and corrosion around the lower bearing of the actuator attach fittings of the inboard and outboard flaps; repairing if necessary; and either overhauling the fittings or replacing them, which ends certain repetitive inspections. The other AD currently requires certain other inspections to detect discrepancies of the actuator attach fittings of the flaps, and follow-on and corrective actions if necessary, which ends the repetitive inspections of the first AD. For certain airplanes, this AD requires new inspections for discrepancies of the actuator attach fittings of the flaps, and follow-on and corrective actions if necessary, which ends the repetitive inspections of both existing ADs. For all airplanes, this AD requires repetitive overhaul/replacements of the actuator attach fittings of both the inboard and outboard flaps. This AD results from reports of cracks of the actuator attach fittings of the trailing edge flaps. We are issuing this AD to prevent cracking and other damage of the actuator attach fittings of the trailing edge flaps, which could result in abnormal operation or \nretraction of a trailing edge flap, and possible loss of controllability of the airplane. \n\nDATES: This AD becomes effective November 8, 2005. \n\n\tOn May 8, 2003 (68 FR 19937, April 23, 2003), the Director of the Federal Register approved the incorporation by reference of Boeing Alert Service Bulletin 747-57A2316, dated December 19, 2002. \n\n\tOn August 3, 2001 (66 FR 34526, June 29, 2001), the Director of the Federal Register approved the incorporation by reference of Boeing Service Bulletin 747-57A2310, Revision 1, dated November 23, 1999; and Boeing Service Bulletin 747-57A2310, Revision 2, dated February 22, 2001.
2005-20-23: The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211 Trent 875, 877, 884, 892, 892B, and 895 series turbofan engines. That AD currently requires repetitive application of dry film lubricant (DFL) to low pressure compressor (LPC) fan blade roots. This AD requires the same actions but at more frequent intervals than the existing AD. This AD also adds the Trent 884B engine to the list of engine models affected, adds a fan blade part number (P/N) to the affected list of fan blades, and relaxes the initial DFL repetitive application compliance time for certain fan blades that have never been removed from the disk. This AD results from discovering DFL in worse condition than anticipated on fan blades fitted to disks previously run for a significant period. This AD also results from the need to update the list of engine models affected, and to update the list of fan blade part numbers affected. We are issuing this AD to prevent LPC fan bladeloss, which could result in an uncontained engine failure and possible aircraft damage.
2005-19-06: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747- 200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. This AD requires repetitive detailed and ultrasonic inspections of the thrust links of the rear engine mounts for any crack or fracture and corrective actions if necessary. This AD results from the finding of a fractured forward lug of the rear engine mount thrust link on the number one strut. We are issuing this AD to detect and correct cracked or fractured thrust links that could lead to the loss of the load path for the rear engine mount bulkhead and damage to other primary engine mount structure, which could result in the in-flight separation of the engine from the airplane and consequent loss of control of the airplane.
2005-19-05: The FAA is adopting a new airworthiness directive (AD) for certain Aerospatiale Model ATR42-500 airplanes. This AD requires inspecting for correct installation of the fastener that attaches the ground braids on the elevator, modifying the forward bonded assembly of the elevator control rod, and corrective action if necessary. This AD results from a functional test of the elevator trim tab control rod of the leading edge, which showed that, in a full-up elevator condition with the tab fully down, interference could occur between the tab control rod and the forward edge of the lower skin of the elevator. We are issuing this AD to prevent discrepancies between the elevator trim tab control rod and the forward edge of the lower skin of the elevator, which could result in reduced control of the elevator and consequent reduced controllability of the airplane.
2005-20-03: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive inspections of the intercostal webs, attachment clips, and stringer splice channels for cracks; and corrective action if necessary. This AD is prompted by reports of fatigue cracks on several Boeing Model 737-200 series airplanes. We are issuing this AD to detect and correct fatigue cracking of the intercostals on the forward and aft sides of the forward entry door, which could result in loss of the forward entry door and rapid decompression of the airplane.
2005-20-01: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive inspections of the stiffeners at left buttock line (LBL) and right buttock line (RBL) 6.15 for cracks; and replacement of both stiffeners with new, improved stiffeners if any stiffener is found cracked. This AD also allows replacement of both stiffeners at LBL and RBL 6.15 with new, improved stiffeners, which terminates the repetitive inspections. This AD is prompted by reports of cracks in the stiffeners at LBL and RBL 6.15 on the rear spar of the wing center section. We are issuing this AD to detect and correct cracks in the stiffeners at LBL and RBL 6.15, which could result in damage to the keel beam structure and consequently reduce the capability of the airplane to sustain flight loads.
2005-19-26: The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model ATP airplanes and Model HS 748 airplanes. This AD requires doing a detailed inspection of the drain pipes of the fuel cross feed system and certain electrical cables for chafe damage; doing an inspection to determine the clearance between the cable loom and the cross feed drain pipe; and doing corrective actions if necessary. This AD results from a fire in the dry area of the wing due to severe chafe damage between an electrical cable and the fuel cross feed drain pipe. We are issuing this AD to prevent chafe damage of the electrical cable and fuel cross feed drain pipe that could lead to fuel leakage from the drain pipe and an ignition source from the electrical cable, which could result in a fire in the dry area of the airplane wing.
2005-19-16: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A320-111 airplanes and Model A320-200 series airplanes. This AD requires installing a bonding strip between each of the two water scavenge jet pumps of the center fuel tank and the rear spar in section 21. This AD results from the results of fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an ignition source for fuel vapor in the wing, which could result in fire or explosion in the center wing fuel tank.
2005-19-13: The FAA is adopting a new airworthiness directive (AD) for all British Aerospace Model HS 748 airplanes. This AD requires modifying the undercarriage of the nose landing gear (NLG). This AD results from a report that pintle pins could be installed in an incorrect manner during maintenance without maintenance personnel being aware (or having feedback) that the pin was installed incorrectly. We are issuing this AD to prevent jamming or collapse of the NLG, which could result in damage to the airplane structure or injury to passengers or crew.
2005-18-14: The FAA is superseding an existing airworthiness directive (AD) that applies to all Dassault Model Falcon 10 series airplanes. The existing AD currently requires revising the airplane flight manual (AFM) and installing a placard in the flight deck to prohibit flight into known or forecasted icing conditions. In lieu of the AFM revision and placard installation, that AD allows identifying the part number of each flexible hose in the wing (slat) anti-icing system, performing repetitive inspections of each hose for delamination, and performing corrective actions if necessary. This AD adds the following actions (also in lieu of the AFM revision and placard installation): New repetitive inspections for delamination at reduced intervals, corrective actions if necessary, and an additional AFM revision to include a statement to track flight cycles when the slat anti-icing system is activated. This AD also provides an option to repetitively replace the existing flexible hoses with improved flexible hoses, which terminates the repetitive inspection requirements. This AD results from a report of in-service delamination of a flexible hose in the slat anti-icing system at a time earlier than previously reported. We are issuing this AD to prevent collapse of the flexible hoses in the slat anti-icing system, which could lead to insufficient anti-icing capability and, if icing is encountered in this situation, could result in reduced controllability of the airplane. DATES: This AD becomes effective September 26, 2005. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of September 26, 2005. On April 26, 2005 (70 FR 18282, April 11, 2005), the Director of the Federal Register approved the incorporation by reference of Dassault Alert Service Bulletin F10-A312, dated February 25, 2005, including the Service Bulletins Compliance Card. We must receive any comments on this AD by November 8, 2005.
2005-18-12: The FAA is adopting a new airworthiness directive (AD) for certain Hartzell Propeller Inc. propellers. This AD requires inspecting the propeller blades and other critical propeller parts for corrosion and mechanical damage. This AD results from two events where a "Z- shank" blade failed and separated and the results of teardown inspections that detected corrosion in the blade bore. We are issuing this AD to detect corrosion and mechanical damage that can cause failure of a propeller, which could result in loss of control of the airplane.
