2023-08-06: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters (Airbus) Model AS332C, AS332C1, AS332L, AS332L1, AS332L2, and EC225LP helicopters. This AD is prompted by modifications developed by Airbus to address a report of an emergency exit window that required excessive pushing force to jettison. This AD requires removing skived polytetrafluoroethylene tape (PTFE tape) (if installed) and replacing certain polychloroprene seals with silicone seals, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits installing a jettisonable window unless the actions required by this AD have been accomplished. The FAA is issuing this AD to address the unsafe condition on these products.
2023-07-10: The FAA is superseding Airworthiness Directive (AD) 96-12-11, which applied to all Canadair Model CL-215-1A10 airplanes. AD 96-12-11 required repetitive inspections to detect discrepancies of the microswitches fitted at the water door actuator; replacement of any discrepant microswitch; and modification of the water door actuator switches, which terminates the repetitive inspections. This AD continues to require the modification of the water door actuator switches. This AD also requires modification of the water door solenoid valve common grounds, adds airplanes to the applicability, and specifies a parts installation limitation for the water door solenoid valve. This AD was prompted by reports of uncommanded opening of the water doors during flight and water scooping. The FAA is issuing this AD to address the unsafe condition on these products.
2000-08-11: This amendment supersedes an existing airworthiness directive (AD), applicable to General Electric Company (GE) CF6-6, CF6-45, and CF6-50 series turbofan engines, that requires revisions to the Time Limits Section of the manufacturer's Instructions for Continued Airworthiness (ICA) to include required enhanced inspection of selected critical life-limited parts at each piece-part exposure. This action would add additional eddy current inspections (ECI) for the high pressure turbine rotor (HPTR) Stage 1 and 2 disks. This action is prompted by additional focused inspection procedures that have been developed by the manufacturer. The actions specified by this AD are intended to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
2014-12-05: We are superseding airworthiness directive (AD) 2007-10-07 for all Turbomeca S.A. Arriel 2B, 2B1, and 2B1A turboshaft engines. AD 2007-10-07 required an inspection of the splines of the coupling assembly and the hydro-mechanical metering unit (HMU) drive gear shaft for wear. This AD requires the same inspection and expands the affected population. This AD also removes Arriel 2B1A engines from the applicability. We are issuing this AD to prevent failure of the HMU drive gear shaft, which could lead to damage to the engine and damage to the airplane.
95-22-03: This amendment adopts a new airworthiness directive (AD) that applies to Beech Aircraft Corporation (Beech) Models 60 and A60 airplanes. This action requires incorporating flight manual supplement revisions into the Airplane Flight Manual (AFM) that would specify a minimum airspeed for operating the affected airplanes in icing conditions. Reports of several incidents and accidents on the affected airplanes related to flight in icing conditions prompted the proposed action. The actions specified by the proposed AD are intended to prevent loss of control of the airplane because of the airplane traveling too slowly in icing conditions.
2023-09-13: The FAA is superseding Airworthiness Directive (AD) 2019-18- 09, which applied to all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G airplanes; and Model C-130A, HP-C-130A, EC-130Q, C-130B, and C-130H airplanes. AD 2019-18-09 required a visual inspection of the center wing upper and lower rainbow fittings for cracks, an eddy current inspection of the center wing lower rainbow fittings for cracks, and replacement if necessary. This AD was prompted by an analysis of reported cracks showing repetitive inspections are needed to adequately address cracked inner tangs of the center wing lower rainbow fittings. This AD requires repetitive inspections of the center wing upper and lower rainbow fittings for cracks and replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
81-14-04: 81-14-04 SHORT BROTHERS LIMITED: Amendment 39-4152. Applies to Model SD3-30 series airplanes, certificated in all categories, which have Menasco Manufacturing main landing gear actuator assembly P/N 17900, Serial numbers MMC-003 through MMC-111, installed. To prevent gear-up landing caused by the main landing gear actuator's inability to unlock, accomplish the following within 500 landings after the effective date of this AD, unless already accomplished: Rework the actuator by cutting a venting groove across the contoured face of the profiled washer in accordance with Short Brothers Limited Service Bulletin No. SD3-32-86 Rev. 2 dated March 4, 1981, or later FAA approved revisions, or in a manner acceptable to the Chief, Seattle Area Aircraft Certification Office, FAA Northwest Region. The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1). All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to the addresses listed above. These documents may also be examined at FAA Northwest Region, 9010 East Marginal Way South, Seattle, Washington 98108. This amendment becomes effective July 8, 1981.
2004-25-19: The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) series airplanes. This AD requires revising the airplane flight manual to provide the flightcrew with procedures and limitations for operating an airplane with out-of-tolerance angle of attack (AOA) transducers. This AD also requires repetitive linearity tests of the AOA transducers, and corrective action if necessary. This AD is prompted by a report of premature wear of the potentiometers in AOA transducers having a certain part number. We are issuing this AD to prevent a delay in the stall computer commands for stall warning, stick shaker, and stick pusher operation, due to premature wear of the potentiometers of the AOA transducers, which may cause the airplane to enter a stall condition, and result in loss of control of the airplane.
2023-08-03: The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model G-1159A and G-1159B airplanes and all Model G-IV and GIV-X airplanes. This AD was prompted by a report that the ground spoiler actuator installation does not preclude improper hydraulic line connections that could result in unintended asymmetrical spoiler deployment. This AD requires incorporating corrective actions that physically prevent improper connection of the hydraulic lines to the ground spoiler actuator. The FAA is issuing this AD to address the unsafe condition on these products.
2023-09-10: The FAA is adopting a new airworthiness directive (AD) for all Saab AB, Support and Services Model 340A (SAAB/SF340A) and SAAB 340B airplanes. This AD was prompted by reports of excessive wear on certain starter generator brushes installed in the starter generator. This AD requires repetitive general visual inspections of the starter generator brushes installed in the starter generator and, depending on findings, replacement of the starter generator, and limits installation of affected generators, 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.
