98-26-01: This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A310 series airplanes, that requires various inspections to detect fatigue cracks at certain locations on the fuselage, horizontal stabilizer, and wings and tail, and repair or modification, if necessary; and installation of doublers. This amendment also adds new inspections and reduces certain inspection intervals. This amendment is prompted by results of full-scale fatigue testing of a Model A310 series airplane, which revealed fatigue cracks at those locations. The actions specified by this AD are intended to prevent reduced structural integrity of the fuselage, horizontal stabilizer, and wings.
2014-09-02: We are adopting a new airworthiness directive (AD) for certain M7 Aerospace LLC Models SA26-T, SA26-AT, SA226-AT, SA226-T, SA226-T(B), SA226-TC, SA227-AC (C-26A), SA227-AT, SA227-TT, SA227-BC (C-26A), SA227-CC, and SA227-DC (C-26B) airplanes. This AD was prompted by reports of jamming of the aileron control cable chain in the pilot and copilot control columns due to inadequate lubrication and maintenance of the chain. This AD requires repetitively replacing and lubricating the aileron chain, sprocket, and bearings in the control columns. We are issuing this AD to correct the unsafe condition on these products.
2003-13-10: The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Corporation (formerly Allison Engine Company, Allison Gas Turbine Division, and Detroit Diesel Allison) models 250-C30R/3, -C30R/ 3M, -C47B, and -C47M turboshaft engines. This AD requires initial and repetitive electrical signal inspections of the hydromechanical unit (HMU) Power Lever Angle (PLA) potentiometer. This AD is prompted by an investigation by the National Transportation Safety Board (NTSB), which revealed that a potential undetected failure of the PLA potentiometer electrical signal could cause uncommanded and sudden changes in engine power. The actions specified in this AD are intended to prevent uncommanded and sudden changes in engine power.
87-08-01: 87-08-01 AVIONS PIERRE ROBIN: Amendment 39-5601. Applies to Model R2160 (all serial numbers) airplanes certificated in any category. Compliance: Required as indicated, unless already accomplished. To preclude the loss of rudder control, accomplish the following: (a) Within the next 10 hours time-in-service (TIS) after the effective date of this AD, visually inspect for cracks the area of each rudder bar adjacent to the point where the vertical and horizontal tubes are joined in accordance with the instructions of Avions Pierre Robin Service Bulletin (S/B) No. 109, dated April 28, 1986 (hereinafter referred to as APR S/B No. 109). If any crack is found, before further flight, reinforce all the rudder bars in accordance with the modification specified in APR S/B No. 109. (b) Within the next 100 hours TIS after the effective date of this AD, unless previously modified in accordance with paragraph (a) of this AD, reinforce all the rudder bars in accordance withthe modification specified in APR S/B No. 109. (c) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished. (d) An equivalent means of compliance with this AD may be used if approved by the Manager, Aircraft Certification Staff, AEU-100, Europe, Africa, and Middle East Office, FAA, c/o American Embassy, B- 1000 Brussels, Belgium. All persons affected by this directive may obtain a copy of the document referred to herein upon request to Avions Pierre Robin, Aerodrome de DIJON-Val-Suzon, Darois, Fontaine-Les-Dijon, France F-21121; or may examine the document referred to herein at FAA, office of the Regional Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106. This amendment becomes effective on April 20, 1987.
2014-08-01: We are superseding Airworthiness Directive (AD) 2014-03-08 for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014- 03-08 required an inspection to determine the part number of the interconnecting struts installed on the wings, identifying the part number and the serial number of the associated target and proximity sensor if applicable, and replacing or re-identifying the flap interconnecting strut if applicable. This new AD corrects a typographical error that affects the definition of a serviceable interconnecting strut. This AD was prompted by a report that an investigation showed that when a certain combination of a target/ proximity sensor serial number is installed on a flap interconnecting strut, a ``target FAR'' signal cannot be detected when it reaches the mechanical end stop of the interconnecting strut. We are issuing this AD to detect and correct a latent failure of the flap down drive disconnection due to an already-failed interconnecting strut sensor, which could result in asymmetric flap panel movement and consequent loss of control of the airplane.
2014-07-07: We are superseding an airworthiness directive (AD) 87-02-04 for British Aerospace (Operations) Limited Model HP.137 Jetstream MK.1, Jetstream Series 200, and Jetstream Series 3101 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 cracking of the forward main landing gear yoke pintle resulting from corrosion pits leading to stress corrosion. We are issuing this AD to require actions to address the unsafe condition on these products.
68-12-01: 68-12-01 SIAI-MARCHETTI: Amdt. 39-607. Applies to Model S.205/22R airplanes, Serial Numbers 213 through 4-125. Compliance required as indicated. To avoid the possibility of flames or harmful gases passing from the engine compartment into the cockpit or other parts of the airplane, within the next 200 hours' time in service after the effective date of this AD, unless already accomplished, incorporate sealing plates and apply fireproof sealant "Stabond HT-4" or an FAA-approved equivalent at the firewall and nose wheel well, in accordance with Siai-Marchetti Service Bulletin No. 205B19, dated January 13, 1968, or later RAI-approved issue, or FAA-approved equivalent. This amendment becomes effective July 5, 1968.
2014-07-01: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747 airplanes. This AD was prompted by reports of cracking in particular areas of the bulkhead structure at body station (BS) 2598. This AD requires repetitive inspections, including post-repair and post-modification inspections, for cracking in the bulkhead structure at BS 2598; certain one-time inspections of certain fasteners and support frame modifications on certain airplanes; related investigative and corrective actions, if necessary; and an interim modification that would terminate certain repetitive inspections. We are issuing this AD to detect and correct fatigue cracking of the BS 2598 bulkhead structure, which could adversely affect the structural integrity of the bulkhead and the horizontal stabilizer support structure, and result in loss of controllability of the airplane.
2025-04-10: The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+/EC635T2+, EC135T3, MBB-BK 117 C-2, MBB-BK 117 D-2, and MBB-BK 117 D-3 helicopters. This AD was prompted by reports of malfunctioning emergency fuel shut-off switches on the warning unit. This AD requires inspecting certain switches on the warning units, and depending on the results, replacing or repairing the warning unit. This AD also allows installing certain warning units provided certain requirements are met. These actions are 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.
2014-07-10: We are adopting a new airworthiness directive (AD) for Ballonbau W[ouml]rner GmbH Models NL-280/STU, NL-380/STU, NL-510/STU, NL-640/STU, NL-840/STU, and NL-1000/STU balloons. 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 current inspection intervals are no longer adequate to ensure timely detection of deterioration or damage. We are issuing this AD to require actions to address the unsafe condition on these products.
