2006-15-17: The FAA is adopting a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires modification of the wiring distribution of the alternating current bus transfer power system and the right-hand and left-hand windshield anti- icing system, as necessary. This AD results from a report of electrical sparks coming out of the flight deck from a panel behind the left seat. We are issuing this AD to prevent failure of the sliding window heating element(s), due to electrical overload, which could result in smoke and fire in the cockpit.
2024-01-08: The FAA is superseding Airworthiness Directive (AD) 2019-16- 11, which applied to certain Airbus SAS Model A300 F4-605R and FR-622R airplanes. AD 2019-16-11 required repetitive high frequency eddy current (HFEC) inspections of the aft lower deck cargo door (LDCD) frame forks; a one-time check of the LDCD clearances; a one-time detailed visual inspection of hooks, eccentric bushes, and x-stops; and corrective actions if necessary. This AD was prompted by a determination that the threshold for the (repetitive) HFEC inspection needs to be corrected, and the LDCD frame forks modified. This AD continues to require the actions in AD 2019-16-11, requires correcting the HFEC inspection threshold and modifying the LDCD frame forks, and prohibits the installation of affected LDCDs under certain conditions; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2024-01-09: The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a report of a steering control unit (SCU) filter plate connector that does not meet the certification requirements for exposure of electronic components to high intensity radiated field environments, which could result in malfunction of the nose wheel steering (NWS) system. This AD requires determining if the SCU is an affected SCU, replacing all affected SCUs, and rigging and testing the NWS control. This AD also prohibits installing an affected SCU on any airplane. The FAA is issuing this AD to address the unsafe condition on these products.
2023-26-08: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This AD was prompted by a determination that a combination of system faults and procedural actions will cause the ground spoilers to deploy in the air. This AD requires revising the existing airplane flight manual (AFM) to add revised procedures. The FAA is issuing this AD to address the unsafe condition on these products.
2008-10-02: The FAA is adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) 172, 175, 180, 182, 185, 206, 207, 208, 210, and 303 series airplanes. This AD requires you to inspect the alternate static air source selector valve to assure that the part number identification placard does not obstruct the alternate static air source selector valve port. If the part number identification placard obstructs the port, this AD requires you to remove the placard, assure that the port is unobstructed, and report to the FAA if obstruction is found. This AD results from reports of improper installation of the part number identification placard on the alternate static air source selector valve. The actions specified by this AD are intended to prevent erroneous indications from the altimeter, airspeed, and vertical speed indicators, which could cause the pilot to react to incorrect flight information and possibly result in loss of control.
2024-01-05: The FAA is superseding Airworthiness Directive (AD) 2022-01- 07, which applied to certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2022-01-07 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD retains the actions required by AD 2022-01-07 and also requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2008-09-14: We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-600, -700, -700C, -800 and -900 series airplanes. This AD requires inspecting ground blocks GD261 and GD264 for corrosion, measuring the electrical bond resistance between the ground blocks and the airplane structure, separating the ground wires for the fuel boost pump circuit between ground blocks GD261 and GD264, and doing corrective actions if necessary. This AD results from a report of random flashes of the six fuel pump low pressure lights and intermittent operation of the fuel boost pumps. We are issuing this AD to prevent the simultaneous malfunction of all six fuel boost pumps, which could cause the engines to operate on suction feed and potentially flame out.
2008-09-15: We are 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 for any cracking of or damage to the left side and right side flight deck No. 2, No. 4, and No. 5 windows and corrective actions if necessary. This AD results from reports of in-flight departure and separation of the flight deck windows. We are issuing this AD to detect and correct cracking in the vinyl interlayer or damage to the structural inner glass panes of the flight deck No. 2, No. 4, and No. 5 windows, which could result in loss of a window and rapid loss of cabin pressure. Loss of cabin pressure could cause crew communication difficulties or crew incapacitation.
2024-01-01: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company (Boeing) Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by reports of undetected water leaks from the faucet control module (FCM) migrating below the passenger floor in multiple lavatory locations during flight, and into the electronic equipment bay(s). This AD requires repetitive general visual inspections of the area under all lavatory washbasins for evidence of intermittent and active leaks at the FCM and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
2023-26-02: The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by reports from the supplier that some overheat detection sensing elements of the bleed air leak detection system were manufactured with insufficient salt fill, which can result in an inability to detect hot bleed air leaks. This AD requires revising the existing airplane flight manual (AFM) to include procedures to prevent takeoff with an active bleed air leak annunciated while on the ground. This AD also requires testing the overheat detection sensing elements, marking each serviceable sensing element with a witness mark, and replacing each nonserviceable part with a serviceable part. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
