2000-16-52: This document publishes in the Federal Register an amendment adopting Emergency Airworthiness Directive (AD) 2000-16-52 which was sent previously to all known U.S. owners and operators of Eurocopter France (ECF) Model AS350B3 helicopters by individual letters. This AD requires visually inspecting the heat shield attachment areas on the tail rotor drive shaft forward fairing (fairing) for a crack. This AD also requires, at specified time intervals, removing the fairing and inspecting the heat shield attachment areas on the fairing for a crack. If a crack is found, this AD requires replacing the fairing with an airworthy fairing. This amendment is prompted by an in-flight loss of the fairing heat shield due to cracking in the areas where the heat shield is attached to the fairing. The actions specified by this AD are intended to prevent an in-flight loss of the heat shield, impact with tail or main rotor blades, and subsequent loss of control of the helicopter.

2005-03-15: The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. This AD requires repetitive inspections to detect discrepancies of the fuselage skin and reinforcing plates along the wing to fuselage fairing access panels on the left- and right-hand sides of the airplane, and repair if necessary. This AD also provides for an optional terminating action for the repetitive inspections. This AD is prompted by a report of chafing on the wing to fuselage fairing panels. We are issuing this AD to prevent chafing of the fuselage skin and reinforcing plates, which could lead to reduced structural integrity of the airplane's fuselage.
2023-17-12: The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd. & Co. KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. This AD was prompted by reports of cracks on affected intermediate-pressure compressor (IPC) rotor shaft balance lands. This AD requires repetitive on-wing or in-shop borescope inspections (BSIs) of the affected IPC rotor shaft balance land for cracks and replacement of any IPC rotor shaft if necessary and prohibits the installation of an affected IPC rotor shaft on any engine, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
95-08-01: This amendment adopts a new airworthiness directive (AD), applicable to certain Jetstream Model 4101 airplanes, that requires modification of the spoiler system. This amendment is prompted by reports of fatigue failures of the tee fittings of the spoiler bleed nipples. The actions specified by this AD are intended to ensure that the tee fittings do not fail, and subsequently lead to loss of the main system hydraulics.
2005-03-08: This amendment adopts a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS350B, BA, B1, B2, B3, C, D, D1, and EC130 B4 helicopters that requires removing and modifying the fuel bleed lever. This amendment is prompted by some cases of loss of the fuel bleed lever in flight. If the tension of the control cable is too low, the cable may vibrate out of its notch, resulting in the fuel bleed lever separating from the hinge. The actions specified by this AD are intended to prevent a fuel bleed lever from separating and striking the tail rotor blade (blade), resulting in damage to or loss of a blade, and subsequent vibration and loss of control of the helicopter.
2023-17-10: The FAA is adopting a new airworthiness directive (AD) for certain Vulcanair S.p.A. Model V1.0 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 identifies the unsafe condition as corrosion on the lower fuselage truss. This AD requires a detailed visual inspection of the right-hand (RH) and left-hand (LH) lower rear attachments of the fuselage truss for corrosion, a tactile inspection of the lower rear attachments for missing sealant, and a general visual inspection of the lower fuselage truss welded pipes for corrosion and the related rivets for missing stems and, depending on findings, additional inspections and actions (including a tap test) and applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
2023-17-04: The FAA is superseding Airworthiness Directive (AD) 2022-04-04 for certain Continental Aerospace Technologies, Inc.
