2008-05-02: The FAA is superseding an existing airworthiness directive (AD), which applies to all EMBRAER Model EMB-135BJ, -135ER, -135KE, - 135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. That AD currently requires reviewing the airplane maintenance records for recent reports of vibration from the tail section or rudder pedals. The existing AD also currently requires repetitively inspecting the skin, attachment fittings, and control rods of rudder II to detect cracking, loose parts, wear, or damage; and related investigative/corrective actions if necessary. This new AD requires the existing repetitive inspection to be done with new service information. This new AD also requires replacing the locking tab washers on the control rods of the rudder II and installing springs on the hinge assemblies of the rudder II, which would terminate the repetitive inspection requirements. This AD results from reports of rudder vibration due to wear. We are issuing thisAD to prevent failure of multiple hinge fittings, which could result in severe vibration, and to prevent failure of the rudder control rods, which could result in jamming of the rudder II; and possible structural failure and reduced controllability of the airplane.
2023-18-01: The FAA is superseding Airworthiness Directive (AD) 2021-26-11 for all Rolls-Royce Deutschland Ltd. & Co. KG (RRD) Model RB211-Trent 875-17, 877-17, 884-17, 884B-17, 892-17, 892B-17, and 895-17 engines. AD 2021-26-11 required replacing the affected fuel pump on at least one affected engine. Since the FAA issued AD 2021-26-11, the FAA has determined that replacing all affected fuel pumps on all installed engines is necessary to address the unsafe condition. This AD was prompted by reports of single-engine events caused by water contamination, which led to corrosion on the fuel pump that resulted in loss of engine thrust. This AD requires replacing the affected fuel pump on at least one engine before further flight and replacing all affected fuel pumps within a specified compliance time. This AD would also prohibit installing any affected engine onto any airplane or any affected fuel pump onto any engine, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
2008-05-10: The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 757-200, -200PF, and -200CB series airplanes powered by Rolls-Royce engines. The existing AD currently requires repetitive inspections of the shim installation between the vertical flange and bulkhead, and repair if necessary. The existing AD also requires, for certain airplanes, an inspection for cracking of the four critical fastener holes in the horizontal flange, and repair if necessary. This new AD retains the requirements of the existing AD, and requires that the existing action be performed on airplanes without conclusive records of previous inspections. This AD results from our determination that an operator did not maintain records of previous inspections that are necessary to determine the appropriate corrective actions. We are issuing this AD to detect and correct cracks, loose and broken bolts, and shim migration in the joint between the aft torque bulkhead and thestrut-to-diagonal brace fitting, which could result in damage to the strut and consequent separation of the strut and engine from the airplane.
2008-04-18: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: It has been found that former revisions of the Maintenance Review Board Report (MRBR) of the EMB-120( ) aircraft do not fully comply with some Critical Design Configuration Control Limitations (CDCCL) and Fuel System Limitations (FSL). These limitations are necessary to preclude ignition sources in the fuel system, as required by RBHA-E88/SFAR-88 (Special Federal Aviation Regulation No. 88). * * * * * The potential of ignition sources, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2023-13-05: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by a report indicating fuselage skin lap splice cracking was found between stations (STA) 767 and STA 787, just below S-14R fuselage skin lap splice, where a lower skin panel buckle intersected the upper skin of the lap splice. Cracking was also found just below S-14R between STA 747 and STA 767. This AD requires an inspection for any repair at certain skin lap splices at S- 4, S-14, and S-24 and depending on the configuration, repetitive inspections for buckling, wrinkling, or bulging at affected skin lap splices and repair, repetitive inspections for cracking at affected locations common to fuselage skin on the left and right sides and repair, and alternative inspections and on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
2008-04-21: We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, and -500 series airplanes. This AD requires repetitive inspections for cracking of the body buttock line (BBL) 0.07 floor beam between body station (BS) 651 and BS 676 and between BS 698 and BS 717, and related investigative and corrective actions if necessary. This AD also provides an optional terminating action for the repetitive inspections. This AD results from reports of cracking in the BBL 0.07 floor beam. We are issuing this AD to prevent failure of the main deck floor beams at certain body stations due to fatigue cracking, which could result in rapid decompression of the airplane.
2008-04-12: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 767-200, -300, and -300F series airplanes. That AD currently requires reworking the surface of the ground stud bracket of the left and right transformer rectifier units (TRUs) and the airplane structure mounting surface, and measuring the resistance from the bracket to the structure and the ground lugs to the bracket using a bonding meter. This new AD revises the applicability of the existing AD to include additional airplanes and requires, among other actions, installation of a new ground stud bracket using faying surface bonding. This AD results from a report of loss of all direct current (DC) power generation during a flight, due to inadequate electrical ground path between the ground bracket of the TRUs/main battery charger (MBC) and the structure. We are issuing this AD to prevent depletion of the main battery while in flight, resulting from the loss of both TRUs and theMBC, and consequent loss of all DC power, which could impact the safe flight and landing of the airplane due to the loss of function or malfunction of essential/critical systems and displays in the cockpit.
2023-16-06: The FAA is adopting a new airworthiness directive (AD) for all Hamilton Sundstrand Corporation (Hamilton Sundstrand) Model 14SF-17 and 14SF-19 propellers. This AD was prompted by a report of an auxiliary motor and pump failing to feather a propeller in flight. This AD requires replacement of a certain auxiliary motor and pump. This AD also prohibits installation of a certain auxiliary motor and pump on any propeller. The FAA is issuing this AD to address the unsafe condition on these products.
2008-04-20: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: During planned maintenance visit on two aircraft, corrosion was found on the upper surface of the wing lower skin panel N[deg]1, inside the Right Hand (RH) inboard dry bay. It was discovered that [certain] access panels * * * had been omitted from the access requirements of the associated AMM (airplane maintenance manual) task (AMM 05-25-40) until the August 2001 revision. The result is that some * * * inspections may have not been fully accomplished due to non-removal of [certain] panels * * *. If the area has not been inspected with the correct access, and if AIRBUS Service Bulletin (SB) A320-57-1121 has not been performed, then some aircraftcould remain insufficiently inspected until the next scheduled inspection. This may result in a high risk of corrosion findings greater than level 1. Corrosion findings greater than level 1 in the wing could result in reduced structural integrity of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2008-04-11: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 707 airplanes, and Model 720 and 720B series airplanes. This AD requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This AD also requires the initial performance of certain repetitive AWL inspections to phase in those inspections, and repair if necessary. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
2023-17-13: The FAA is adopting a new airworthiness directive (AD) for all BRP-Rotax GmbH & Co KG (Rotax) Model 912 F2, 912 F3, 912 F4, 912 iSc2 Sport, 912 iSc3 Sport, 912 S2, 912 S3, 912 S4, 914 F2, 914 F3, and 914 F4 engines; and Model 912 A, 912 A2, and 912 A3 engines included as part of the type certificated aircraft type design for various aircraft. This AD was prompted by a report of surface abnormalities on the affected propeller shaft, which could lead to increased wear of the propeller shaft bearings. This AD requires initial and repetitive inspections of the magnetic plug for the accumulation of metal chips to assess the condition of the propeller gearbox for wear of the propeller shaft bearings and removal of the affected propeller shaft from service and replacement with a part eligible for installation as a terminating action either immediately or at a certain time depending on inspection findings. This AD also prohibits installation of the affected propeller shaft on any engine. The FAA is issuing this AD to address the unsafe condition on these products.
2008-04-07: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Subsequent to accidents involving Fuel Tank System explosions in flight * * * and on ground, the FAA has published Special Federal Aviation Regulation 88 (SFAR88) * * * [which] required * * * [conducting] a design review against explosion risks. The unsafe condition is the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2008-04-09: We are adopting a new airworthiness directive (AD) to supersede AD 2007-16-14, which applies to all Taylorcraft (Taylorcraft) A, B, and F series airplanes. AD 2007-16-14 currently requires you to do an initial visual inspection of the left and right wing front and aft lift struts for cracks and corrosion and replace any cracked strut or strut with corrosion that exceeds certain limits. If the strut is replaced with an original design vented strut, AD 2007-16-14 requires you to repetitively inspect those struts thereafter. Since we issued AD 2007-16-14, we determined that the eddy current inspection method does not address the unsafe condition for the long term. We also determined that Models FA-III and TG-6 airplanes are not equipped with the affected struts. Consequently, this AD retains the actions required in AD 2007-16-14, except it removes the eddy current inspection method (provides 24-month credit if already done using this method), adds the radiograph method as an inspection method, changes the Applicability section, and changes the compliance time between the repetitive inspections. We are issuing this AD to detect and correct cracks and corrosion in the left and right wing front and aft lift struts. This condition, if not corrected, could result in failure of the lift strut and lead to in-flight separation of the wing. DATES: This AD becomes effective on March 28, 2008. On March 28, 2008, the Director of the Federal Register approved the incorporation by reference of Taylorcraft Aviation, LLC Service Bulletin No. 2007-001, Revision B, dated October 15, 2007, listed in this AD. As of August 20, 2007 (72 FR 45153, August 13, 2007), the Director of the Federal Register approved the incorporation by reference of Taylorcraft Aviation, LLC Service Bulletin No. 2007-001, Revision A, dated August 1, 2007, listed in this AD.
2023-15-06: The FAA is adopting a new airworthiness directive (AD) for all Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes.

The MCAI describes the unsafe condition as: [T]he FAA has published a set of new rules related to the fuel tank safety, including the Special Federal Aviation Regulation 88 (SFAR 88). The JAA (Joint Aviation Authority) has issued an Interim Policy JAA INT/POL 25/12, to recommend the application of a similar requirement to the National Aviation Authorities (NAA) [of Europe]. * * * * * * * * ATR carried out a safety review on the fuel tank systems and zones adjacent to the fuel tanks on all ATR models * * *. * * * * * The unsafe condition is the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2008-04-03: We are adopting a new airworthiness directive (AD) for Eurocopter Model AS-365N2 and N3, SA-365C, C1 and C2, and SA-365N and N1 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency (EASA), the Technical Agent for France, with which we have a bilateral agreement, states in the MCAI: This Emergency Airworthiness Directive is issued following several reports of tightening torque loss detected on the main rotor hub (MRH)-to-main rotor mast bolted attachment. These findings were made on EUROCOPTER-assembled attachments with less than 300 operating hours. A loss of tightening torque on the MRH-to-main rotor mast attachment bolt could lead to loss of the main rotor head. This AD requires actions that are intended to address the unsafe condition caused by a loss of tightening torque on the MRH attachment bolts.
2023-16-01: The FAA is superseding Airworthiness Directive (AD) 2023-12- 20, which applied to certain Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. AD 2023-12-20 required replacing certain oxygen system hoses and prohibited installing affected oxygen hoses. Since the FAA issued AD 2023-12-20, the FAA has learned of an error in a required compliance time. This AD retains the requirements of AD 2023-12-20, with a revised compliance time for the replacement. The FAA is issuing this AD to address the unsafe condition on these products.
2008-04-05: We are adopting a new airworthiness directive (AD) for Eurocopter Deutschland (Eurocopter) Model EC135 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The European Aviation Safety Agency (EASA), the Technical Agent for the Federal Republic of Germany, with which we have a bilateral agreement, states in the MCAI: During a flight a burning odour [sic] could be smelled in the cabin. Its reason was a short circuit in the LH cable channel, which was caused by a damaged wire harness. The wire harness was damaged by the side channel cover's attachment hardware. The rubbing and chafing of the wiring harnesses in the tunnels underneath the channel cover, against the screws and rivets attaching the channel covers, could lead to a short circuit of the wiring harness. This AD requires actions that are intended to address this unsafe condition by preventing a short circuit resulting from a damaged wiring harness, which could subsequently lead to a fire in the helicopter.
2023-14-10: The FAA is superseding Airworthiness Directive (AD) 2019-21- 06, which applied to certain Ipeco Holdings Limited (Ipeco) pilot and co-pilot seats. AD 2019-21-06 required modification and re- identification of the affected seats, initial and repetitive inspections of the affected track lock springs and, depending on the findings, replacement of the track lock springs with a part eligible for installation. Since the FAA issued AD 2019-21-06, the FAA determined the need for a mandatory terminating action to the track lock spring inspections. This AD is prompted by reports of track lock spring failures occurring on affected seats. This AD retains the requirements of AD 2019-21-06. This AD also adds a mandatory terminating action for the initial and repetitive inspections of the affected track lock springs.
