2023-25-05: The FAA is superseding Airworthiness Directive (AD) 2022-07- 15, which applied to all Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2022-07-15 required replacing affected braking and steering control units (BSCUs) and revising the operator's existing FAA-approved minimum equipment list (MEL). This AD was prompted by a determination that a type 1 relay combined with an affected BSCU would induce BSCU freezing. This AD removes certain airplanes from the applicability, retains the requirements of AD 2022-07-15, requires an inspection for the relay type installed and replacement of type 1 relays with type 2 relays, limits the installation of affected BSCUs on certain airplanes and prohibits the installation of affected BSCUs for certain other airplanes 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.
2008-08-26: We are adopting a new airworthiness directive (AD) for all Boeing Model 767 airplanes. This AD requires a one-time inspection to determine the material of the forward and aft gray water drain masts. For airplanes having composite gray water drain masts, this AD also requires installation of a ground bracket and a bonding jumper between a ground bracket and the clamp on the tube of the forward and aft gray water composite drain masts. This AD results from a report of charred insulation blankets and burned wires around the forward gray water composite drain mast found during an inspection of the forward cargo compartment. We are issuing this AD to prevent a fire near a composite drain mast and possible disruption of the electrical power system caused by a lightning strike on a composite drain mast, which could result in the loss of several functions essential for safe flight.
2023-25-15: The FAA is superseding Airworthiness Directive (AD) 2020-24- 12, which applied to certain Airbus SAS Model A350-941 airplanes. AD 2020-24-12 required replacing certain center wing box (CWB) fasteners with fasteners having improved friction efficiency. This AD was prompted by reports that certain CWB fasteners had rotated inside the fastener holes due to insufficient friction for the application, and by the determination that additional work is necessary to ensure the correct application of the fuel vapor barrier structure paint on the outside of the CWB. This AD continues to require the actions in AD 2020-24-12; and requires the additional work; as specified in 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.
2008-08-18: 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: [L]eakage of hot wing anti-icing air from the Peri-seal housing. This results in an uncontrolled flow of high-pressure hot air to enter the forward (anti-icing) plenum chamber of the wing leading edge, potentially damaging the anti-icing barrier webs. Subsequently, the wing auxiliary spar can also be damaged by high- pressure hot air. * * * [D]eterioration of the Peri-seals enables the piccolo tubes to vibrate, resulting in a broken piccolo tube. * * * This condition, if not corrected, may cause heat damage to the front spar that potentially affects the wing's load capability. We are issuing this AD to require actions to correct the unsafe condition on these products.
2008-08-17: The FAA is adopting a new airworthiness directive (AD) for certain Kelly Aerospace Power Systems turbochargers. This AD requires a onetime visual inspection of suspect turbochargers for an excessive gap between the turbocharger turbine housing flange and the exhaust tube flange, and replacement of turbochargers that fail the gap inspection. This AD results from two reports of exhaust leakage occurring between the turbocharger turbine housing flange and the exhaust tube flange due to machining defects of the turbocharger turbine housing flange. We are issuing this AD to prevent hazardous amounts of carbon monoxide from entering the cabin, an increase in under-cowl temperatures hampering engine and accessory function, and loss of tailpipe retention, which could lead to an in-flight fire and loss of control of the airplane.
2023-25-03: The FAA is adopting a new airworthiness directive (AD) for certain Piaggio Aviation S.p.A. (Piaggio) Model P-180 airplanes. This AD is prompted by a report of corrosion on the various aluminum alloy reinforcements in the horizontal stabilizer (HS) central box caused by a humid environment inside the box from water ingress and/or condensation. This AD requires a one-time detailed inspection of the HS central box for corrosion; an assessment of the corrosion level; and depending on the determination, repetitive detailed inspections of the HS central box for corrosion and the internal composite structure for surface cracks, distortion, and damage; and repair or replacement of the HS assembly. Repair or replacement of the HS assembly is terminating action for the repetitive inspections. The FAA is issuing this AD to address the unsafe condition on these products.
2023-22-09: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a report that the axis index washers on the forward and rear main landing gear door hinges were found inverted in production. This AD requires a one-time detailed inspection of the axis index washers for correct installation, and, depending on findings, replacement of the axis index washers, 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.
2008-06-07: The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. That AD currently requires an accelerated schedule of repetitive testing of the elevator servo control loops, and corrective actions if necessary. This new AD retains the existing requirements, reduces the applicability of the existing AD, and adds terminating actions. This AD results from reports of failed elevator servo controls due to broken guides. We are issuing this AD to prevent failure of the elevator servo controls during certain phases of takeoff, which could result in an unannounced loss of elevator control and consequent reduced controllability of the airplane.
2008-06-52: This document publishes in the Federal Register an amendment adopting emergency airworthiness directive (AD) 2008-06-52 that was sent previously to all known U.S. owners and operators of certain TAE Model TAE 125-02-99 engines. This AD requires, before further flight, replacing the high-pressure fuel line and installing a high-pressure fuel line support. This AD results from reports of in-flight engine shutdown incidents on airplanes equipped with TAE 125-02-99 engines. We are issuing this AD to prevent an in-flight engine shutdown or engine fire due to a cracked fuel line.
2023-24-06: The FAA is superseding Airworthiness Directive (AD) 2021-25-04 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000 engines. AD 2021-25-04 required operators to revise the airworthiness limitations section (ALS) of their existing approved continuous airworthiness maintenance program by incorporating the revised tasks of the applicable time limits manual (TLM) for each affected model turbofan engine. Since the FAA issued AD 2021-05-04, the manufacturer revised the TLM to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, which prompted this AD. This AD requires revising the ALS of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, 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.
