2024-12-10: The FAA is adopting a new airworthiness directive (AD) for all Centerpointe Aerospace Inc. (Centerpointe) Model S-58BT, S-58DT, S- 58ET, S-58FT, S-58HT, and S-58JT helicopters. This AD was prompted by an indication of a crack on the angle gearbox mount (AGBM). This AD requires repetitively performing a fluorescent penetrant inspection (FPI) of the AGBM at specified time intervals and, depending on the results, removing the AGBM from service. The FAA is issuing this AD to address the unsafe condition on these products.
2024-11-02: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a determination that new or more restrictive maintenance tasks are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance tasks. The FAA is issuing this AD to address the unsafe condition on these products.
2008-13-29: We are adopting a new airworthiness directive (AD) for all McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD- 83), DC-9-87 (MD-87), and MD-88 airplanes. This AD requires repetitive inspections for cracking of the overwing frames from stations 845 to 905 (MD-87 stations 731 to 791), left and right sides, and corrective actions if necessary. This AD results from reports of cracked overwing frames. We are issuing this AD to detect and correct such cracking, which could sever the frame, increase the loading of adjacent frames, and result in damage to adjacent structure and loss of overall structural integrity of the airplane.
2024-14-04: The FAA is adopting a new airworthiness directive (AD) for all International Aero Engines, LLC (IAE LLC) Model PW1122G-JM, PW1124G1- JM, PW1124G-JM, PW1127G1-JM, PW1127G1A-JM, PW1127G1B-JM, PW1127G-JM, PW1127GA-JM, PW1129G-JM, PW1130G-JM, PW1133G-JM, and PW1133GA-JM engines. This AD was prompted by an in-flight shutdown (IFSD) caused by the fracture of a low-pressure compressor (LPC) 1st-stage integrally bladed rotor (IBR-1). This AD requires removal and replacement of affected LPC key washers and affected LPC IBR-1 and installation of inlet guide vane (IGV) spacers. The FAA is issuing this AD to address the unsafe condition on these products.
2024-12-08: The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This AD was prompted by a report of a landing gear not locked indication during the final approach, which led the flight crew to declare an emergency. This AD requires reviewing maintenance records of the main landing gear (MLG) assemblies to determine whether the MLG was modified according to a certain service bulletin or restored during overhaul maintenance; inspecting the left and right MLG locking-stay bracket assemblies to verify that the correct attaching hardware is correctly installed on the brackets; replacing nuts having certain part numbers (P/Ns); replacing the locking-stay bracket assembly, if necessary; and prohibits the installation of affected parts on the MLG locking-stay bracket assembly; as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2008-13-24: 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 on in-service aircraft that some aileron tab bellcrank assemblies were not in accordance with the definition drawings. The main item concerned is the retainer Part Number S2711004620000, which has been manufactured with a hole larger than it should be, or redrilled out of limits. The function of the retainer is to maintain the spacer in position in case of rupture or loss of the bolt which links the tab control rod to the bellcrank assembly. If the diameter of the retainer hole is out of limit, the retainer function is lost and fail-safe installation is no longer ensured. This condition, if not corrected, could lead to loss of theaileron tab bellcrank functionality, resulting in diminished control of the aircraft. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
2008-14-11: We are adopting a new airworthiness directive (AD) for certain Boeing Model 777-200, -200LR, -300, and -300ER series airplanes. This AD requires a one-time inspection to determine the part number of the cargo compartment fire suppression filter/regulator. This AD also requires, for certain airplanes, a revision of the "Maximum Diversion Time in Minutes'' for ETOPS operation specified in the Operations Specifications. For certain airplanes, this AD also provides for optional replacement of the cargo compartment fire suppression filter/ regulator, which would allow revision of the "Maximum Diversion Time in Minutes'' for ETOPS operation specified in the Operations Specifications to restore the airplane's full ETOPS capability. This AD results from a report that the filter/regulator installed in the cargo fire suppression system did not meter the Halon for the certified duration during ETOPS flight tests. We are issuing this AD to prevent ETOPS operation with insufficient cargo fire suppression capability, which could result in an uncontained fire in the cargo compartment.
2024-13-02: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes and Model 737-700, -800, and -900ER series airplanes. This AD was prompted by multiple reports of passenger service unit (PSU) oxygen generators shifting out of position within their associated PSU assemblies because of a retention failure. This AD requires a general visual inspection of the PSU oxygen generator installation to determine the configuration of the thermal pads of the retention straps and applicable on-condition actions. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
2008-14-10: We are adopting a new airworthiness directive (AD) for all Lockheed Model 382, 382B, 382E, 382F, 382G, and 382J series airplanes. This AD requires, among other actions, an inspection to determine whether a certain upper engine mount bolt is installed, and replacement of any discrepant upper engine mount bolt with a new one. This AD results from a report indicating that several upper engine mount bolts manufactured by a certain supplier broke during installation. We are issuing this AD to prevent failure of the upper engine mount bolts, which could result in reduced structural capability of an engine mount, and possible separation of a strut and engine from the airplane during flight.
2008-13-23: 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 maintenance water has been found in the elevator [assembly]. The unsafe condition is water or ice accumulating in the elevator assembly, which could result in corrosion and consequent reduced structural integrity of the flight control surface, or an unbalanced flight control surface. These conditions could result in reduced controllability of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
