2003-13-07: This amendment adopts a new airworthiness directive (AD) that applies to all Short Brothers and Harland Ltd. (Shorts) Models SC-7 Series 2 and SC-7 Series 3 airplanes. This AD requires you to repetitively inspect all flight control system rods for corrosion and cracks, replace any cracked rod, and repair corrosion damage or replace any corroded rod depending on the extent of the damage. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by this AD are intended to prevent failure of any flight control system rod caused by cracks or corrosion. Such failure could lead to complete failure of the flight control system with consequent loss of control of the airplane.
2013-26-07: We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by reports of certain sliding windows that were difficult to operate after landing. This AD requires a detailed inspection to identify part numbers of sliding windows and sliding window seals, and modification if necessary. This AD also includes an optional replacement. We are issuing this AD to detect and correct incorrect seals, which could lead to the functional loss of the sliding window as an exit, possibly preventing the flightcrew from safely evacuating the airplane during an emergency.
2013-26-06: We are superseding airworthiness directive (AD) 2010-19-01 for certain Rolls-Royce Corporation (RRC) AE 3007A series turbofan engines. AD 2010-19-01 required removing certain high-pressure turbine (HPT) stage 2 wheels, or performing inspections on them, and reduced their approved life limits. This new AD clarifies the AE 3007A turbofan engine model applicability, further reduces the approved life limits of affected HPT stage 2 wheels, and eliminates the inspections required by the existing AD. This AD was prompted by additional analysis that concluded that lower life limits for the affected HPT stage 2 wheels are necessary. We are issuing this AD to prevent uncontained failure of the HPT stage 2 wheel, damage to the engine, and damage to the airplane.
2013-26-04: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, -400D, and -400F series airplanes. This AD was prompted by a report of water leakage into the main deck cargo wire integration unit (WIU). The water flowed from the main deck floor panels, through disbonded seams in the aft main equipment center (MEC) drip shield gutter, then onto the WIU. This AD requires cleaning the aft MEC drip shield gutter; and doing a one-time general visual inspection for disbonded seams, and repair if necessary. This AD also requires installing a fiberglass reinforcement overcoat to the underside of the bonded seams of the aft MEC drip shield gutters. We are issuing this AD to prevent water penetration into the MEC, which could result in the loss of flight critical systems.
2018-07-17: We are adopting a new airworthiness directive (AD) for certain Safran Helicopter Engines, S.A., Arrius 2B1, 2B1A, 2B2, and 2K1 turboshaft engines. This AD requires inspecting the power turbine wheel (PTW) assembly and replacing the PTW if the turbine blade dampers are found missing. This AD was prompted by the manufacturer reporting a number of PTW assemblies may have been assembled without the blade dampers. We are issuing this AD to address the unsafe condition on these products.
2013-26-01: We are adopting a new airworthiness directive (AD) for all CFM International (CFM) S.A. CFM56-3 and CFM56-7B series turbofan engines with certain accessory gearboxes (AGBs) not equipped with a handcranking pad ``oil dynamic seal'' assembly. This AD was prompted by 42 events of total loss of engine oil from CFM56 series turbofan engines while in flight. This AD requires an independent inspection to verify re-installation of the handcranking pad cover after removal of the pad cover for maintenance until installation of a handcranking pad oil dynamic seal assembly. We are issuing this AD to prevent loss of engine oil while in flight, which could result in engine failure, loss of thrust control, and damage to the airplane.
2025-05-15: The FAA is adopting a new airworthiness directive (AD) for all General Electric Company (GE) Model CT7-2E1 engines. This AD was prompted by a revised analysis using an updated stress model, which calculated that the actual life limit of the CT7-2E1 stage 2 turbine aft cooling plate is less than the current life limit. This AD requires revision of the airworthiness limitations section (ALS) of the existing CT7-2E1 engine maintenance manual (EMM) and the operator's existing approved maintenance program or inspection program, as applicable, to incorporate a reduced life limit for this part. The FAA is issuing this AD to address the unsafe condition on these products.
2003-12-13: This amendment adopts a new airworthiness directive (AD) for Agusta S.p.A (Agusta) Model A109K2 helicopters. This action requires a visual check of each tail rotor blade (blade) for a crack; a visual inspection of each blade for a crack at specified intervals; and if necessary, a dye-penetrant inspection. Replacing any cracked blade with an airworthy blade before further flight is also required. This amendment is prompted by a report of a crack that occurred on an Agusta Model A109K2 blade. The actions specified in this AD are intended to detect fatigue cracks on the blades, which could result in loss of the blades and loss of control of the helicopter.
2018-07-10: We are adopting a new airworthiness directive (AD) for Embraer S.A. Models EMB-500 and EMB-505 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 improperly tied castle nuts on the aileron, rudder, and elevator trim tab (or autotab) attachment bolts. We are issuing this AD to require actions to address the unsafe condition on these products.
2013-26-02: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a report that traces of oil could be found in the crew oxygen system due to the use of incorrect pressure testing procedures during manufacturing. This AD requires cleaning the crew oxygen system. We are issuing this AD to detect and correct oil contaminants, which could cause an ignition and result in a fire in the oxygen system.
