2016-05-10: We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters with certain external life rafts. This AD requires installing a sheath kit on the left-hand and right-hand raft deployment control systems. This AD is prompted by a report that the life raft deployment control could not be adjusted due to problems with the life raft deployment linkage. This unsafe condition, if not corrected, could result in failure of the external life raft to deploy and prevent evacuation of passengers during an emergency.
46-12-01: 46-12-01 CESSNA: (Was Mandatory Note 8 of AD-722-5.) Applies Only to AT-17 and UC-78 Series Airplanes. Inspection required immediately. On all AT-17 or UC-78 Series airplanes that have not been re-covered with grade A fabric at time of (or subsequent to) the original civil certification, inspect the fabric on wings and control surfaces to determine that the fabric complies with grade A fabric standards and has a sample breaking strength of at least 56 pounds. The lacing cord should also be checked and should have a breaking strength of at least 56 pounds when tested double. This inspection will require the testing of one or more samples of fabric and cord, the location from which the samples are to be taken and the number necessary will be determined by the CAA representative.
2024-23-09: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A321-251NX, -252NX, -253NX, -271NX, and -272NX airplanes. This AD was prompted by the discovery during a quality review performed during manufacturing, that a torque strip indicator (material "Dykem") had been applied on the orifice fitting on certain slides' inflation reservoirs' venting holes. This AD requires an inspection for discrepancies of affected parts (certain reservoirs having certain orifices) and replacement of discrepant affected parts, and prohibits installing affected 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.
99-18-18 R1: This amendment revises an existing airworthiness directive (AD) that is applicable to Dowty Aerospace Propellers Model R381/6-123-F/5 propellers, that requires initial and repetitive visual and ultrasonic inspections of propeller blades for cracks across the camber face, and, if blades are found cracked, replacement with serviceable blades. This amendment is prompted by an engineering analysis of field service data and certification testing that indicate that the repetitive visual inspection interval can be safely increased and that the ultrasonic inspections can be eliminated. The actions specified in this proposed AD are intended to detect propeller blade cracks and propagation, which if not detected could result in propeller blade separation and possible aircraft loss of control.
2016-03-03: We are superseding airworthiness directive (AD) 2013-11-13 for all Rolls-Royce plc (RR) Viper Mk. 601-22 turbojet engines. AD 2013-11- 13 required reducing the life of certain critical parts. This AD adds two new engine models and additional engine parts to the applicability. This AD was prompted by a determination by RR that additional parts for the RR Viper Mk. 601-22 as well as additional engine models are affected. We are issuing this AD to prevent failure of life-limited parts, which could lead to an uncontained part release, damage to the engine, and damage to the airplane.
51-02-02: 51-02-02 TEMCO: Applies to All Models GC-1A and GC-1B Airplanes Through Serial Number 3760, Except Those Equipped With Hanlon-Wilson Muffs. Compliance required by February 15, 1951. To prevent engine malfunctioning due to pieces of asbestos from the carburetor heat muff entering the carburetor, remove all asbestos strips on the right-hand (carburetor heat) muff. After removal of the asbestos, peen the muff collars to provide a tight fit on the exhaust stacks. This supersedes AD 47-25-08.
2024-24-07: The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by a determination that the overhead bin attachment could fail under certain conditions. This AD requires replacing existing overhead bin hook assemblies and support tubes with a different type, as specified in a Transport Canada AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.
2016-03-07: We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200, -200 Freighter, and -300 series airplanes, and all Airbus Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of premature aging of certain chemical oxygen generators in the passenger compartment that resulted in failure of the generators to activate. This AD requires inspecting to determine if certain passenger chemical oxygen generators are installed, and replacement of affected generators. We are issuing this AD to prevent failure of the chemical oxygen generator to activate during an emergency situation, which could result in unavailability of oxygen and possible incapacitation of the occupants.
2024-24-06: The FAA is superseding Airworthiness Directive (AD) 2023-03- 09, which applied to certain ATR-GIE Avions de Transport R[eacute]gional Model ATR72-101, -102, -201, -202, -211, -212, and - 212A airplanes. AD 2023-03-09 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2023-03- 09 and 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.
2003-07-13: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 757 series airplanes, that currently requires repetitive inspections for excessive wear of the internal and external splines of the torque tube couplings of the trailing edge flaps, and replacement of the couplings, if necessary. That AD also provides an optional modification that, if installed, constitutes terminating action for the inspection requirements. This amendment expands the applicability of the existing AD and requires new inspections of the torque tube assemblies and certain gearbox assemblies and universal joints in the drive system for the inboard trailing edge flaps, and follow-on actions if necessary. For certain airplanes, this amendment also adds a new optional modification, which, if installed, terminates certain inspections. The actions specified by this AD are intended to prevent separations in the drive system for the inboard trailing edge flaps, which could cause a flap skew condition that could result in damage to the flaps or fuselage, and consequent reduced controllability of the airplane.
