94-18-01: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 757 and 767 series airplanes, that requires modification of the latch hook installation for the number two cockpit window frame. This amendment is prompted by reports of the flight crew executing rejected takeoffs (RTO) and air turnbacks (ATB) due to false "closed" indications for the number two cockpit window. The actions specified by this AD are intended to prevent unlatched (not completely closed) number two cockpit windows and the resultant execution of RTO's and ATB's by the flight crew.
2002-14-11: This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that currently requires replacing the ground support bracket(s); and rerouting the ground cables of the galley external power and main external power, or ground cables of the main external power; as applicable. This amendment requires a general visual inspection of the ground cables of the main external power and galley external power for excessive length, as applicable; and corrective actions, if necessary. This amendment is prompted by the FAA's determination that currently required actions may not adequately address the identified unsafe condition. The actions specified by this AD are intended to prevent arcing and heat damage to the attachment points of the main external and galley power receptacle ground wire, insulation blankets outboard and aft of the receptacle area, and adjacent power cables, which could result in smoke and fire inthe forward cargo compartment. \n\n\tThe incorporation by reference of McDonnell Douglas Alert Service Bulletin MD11-24A138, dated April 3, 2000, as listed in the regulations, was approved previously by the Director of the Federal Register as of January 8, 2001 (65 FR 75616, December 4, 2000).
2002-14-09: This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 and MD-11F airplanes, that currently requires replacement of the existing terminal strips and supports above the main cabin area; and installation of spacers between terminal strips and mounting brackets in the avionics compartment; as applicable. This amendment requires replacing the applicable terminal strips in the avionics compartment with new terminal strips. This amendment also requires performing an inspection to detect arcing damage of the surrounding structure of the terminal strips and electrical cables in the avionics compartment, and repairing or replacing any damaged component with a new component. This amendment is prompted by reports of arcing between the power feeder cables and support brackets of the terminal strips on airplanes previously modified per the existing AD. The actions specified by this AD are intended to prevent electrical arcingcaused by power feeder cable terminal lugs grounding against terminal strip support brackets, which could result in smoke and fire in the main cabin or avionics compartment. \n\n\tThe incorporation by reference of McDonnell Douglas Alert Service Bulletin MD11-24A150, dated March 25, 1999, as listed in the regulations, was approved previously by the Director of the Federal Register as of March 23, 2000 (65 FR 8025, February 17, 2000).
2023-19-04: The FAA is adopting a new airworthiness directive (AD) for all Aircraft Industries, a.s. Model L-420, L 410 UVP-E20, and L 410 UVP-E20 CARGO airplanes. This AD was prompted by reports of the pressure plates within the main landing gear (MLG) wheel brake unit malfunctioning. This AD requires replacing certain MLG wheel brake units with serviceable parts and prohibits installing an affected part on any airplane. The FAA is issuing this AD to address the unsafe condition on these products.
94-14-14: This amendment adopts a new airworthiness directive (AD) that applies to certain Piper Aircraft Corporation (Piper) PA28R, PA28RT, and PA44 series airplanes. This action requires installing a certain nose landing gear modification kit. Several service difficulty reports of collapsed nosegear on the affected airplanes prompted this action. In particular, these reports reveal failure of the bolt (AN4-20) connecting the lower drag link of the nosegear to the upper drag link. The actions specified by this AD are intended to prevent nose gear collapse because of AN4-20 bolt failure, which could lead to airplane damage.
2002-14-15: This amendment supersedes an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that currently requires an inspection of the powered drive unit power wires within three feet of each affected powered drive unit termination for mechanical damage; and repair, if necessary. That AD also currently requires revising the wire harnesses; splicing any additional length wire; routing and installing parts; and replacing the floor panels with new and retained floor panels. This amendment revises the existing requirements by improving the routing of the wire harnesses. This amendment is prompted by the FAA's determination that the currently required modification does not adequately preclude the identified unsafe condition. The actions specified in this AD are intended to ensure that the powered roller pans are positioned properly. Improperly positioned powered roller pans could pierce a powered roller wire harness and cause sparkingthat could ignite adjacent insulation material, which could result in smoke and fire in the center cargo compartment of the airplane.
2023-18-02: The FAA is superseding Airworthiness Directive (AD) 2020-06- 10, which applied to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2020-06-10 required repetitive inspections for cracking of the vertical stiffeners of the left- and right-hand sides of the window frames and corrective actions if necessary. Since the FAA issued AD 2020-06-10, it was determined that certain compliance times need to be reduced. This AD retains the requirements of AD 2020-06-10, with amended compliance times, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
2002-14-07: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 and -11F airplanes, that requires relocation of the mod block tracks on the flight compartment floor beams in the avionics compartment beneath the Captain's and First Officer's seats. This action is necessary to prevent chafing and compression of electrical wiring at the upper track mod blocks on the flight compartment floor beams in the avionics compartment beneath the Captain's and First Officer's seats, which could result in electrical arcing and consequent smoke and/or fire in the cockpit. This action is intended to address the identified unsafe condition.
2023-18-03: The FAA is adopting a new airworthiness directive (AD) for all Viking Air Limited (Viking) (type certificate previously held by Bombardier Inc. and de Havilland, Inc.) Model DHC-3 airplanes. 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 corrosion, wear, and fatigue-related degradation in aging aircraft. This AD requires incorporating into the existing maintenance records for your airplane the actions and associated thresholds and intervals, including life limits, specified in a supplemental inspection and corrosion control manual for Model DHC-3 airplanes. This AD also requires completing all the initial tasks identified in this manual and reporting corrosion findings to Viking. The FAA is issuing this AD to address the unsafe condition on these products.
94-13-04: This amendment adopts a new airworthiness directive (AD), applicable to Schweizer Aircraft Corporation and Hughes Helicopters, Inc. Model 269A, 269A-1, 269B, 269C, and TH-55A series helicopters, that requires mandatory replacement of all the clevis pins associated with the belt drive clutch control installation. This amendment is prompted by an accident involving the separation of the belt drive clutch control spring assembly (spring assembly) from the idler pulley assembly. The actions specified by this AD are intended to prevent separation of the spring assembly from the idler pulley assembly, loss of power to the main rotor system, and a subsequent forced landing.
