2020-03-15: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A321-211, -212, -213, -231, and -232 airplanes. This AD was prompted by a report of erroneous positioning of affected parts on the skin of the fuselage during the pre-drill phase, which could result in unwanted drill-starts. This AD requires inspections for the presence of unwanted drill-starts on affected parts, and an inspection for cracks and corrective action if necessary, 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.
94-14-01: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires replacement of the thrust reverser flow restrictor devices with one-way (check) valve restrictors. This amendment is prompted by reports of piston seal leakage found during actuator overhaul on certain Model 767 series airplanes. The actions specified by this AD are intended to prevent possible deployment of a thrust reverser in flight and subsequent reduced controllability of the airplane.
2007-26-18: We are adopting a new airworthiness directive (AD) for the products listed above. 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 describes the unsafe condition as: "An accumulator cylinder had material defects and suffered an in-flight burst failure causing damage to the aircraft structure.'' We are issuing this AD to require actions to correct the unsafe condition on these products.
2001-12-11: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model DHC-7 series airplanes, that requires modification of the pressure hoses to the ground spoiler actuators. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent blockage of pressure hoses to the ground spoiler actuators, leading to uncommanded deployment of the ground spoilers, resulting in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
2020-03-19: The FAA is adopting a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
94-14-03: This amendment adopts a new airworthiness directive (AD), applicable to certain Nordskog water heaters and coffee makers. This amendment requires an inspection to determine whether certain discrepant pressure relief valves have been installed in certain galley water heaters and coffee makers; and either replacement of the discrepant valves, or discontinued use of the water heaters or coffee makers and installation of placards indicating that these units are not to be used. This amendment is prompted by reports of injuries to cabin crew members that resulted from explosions of galley water heaters. The actions specified by this AD are intended to prevent explosions of galley water heaters and coffee makers, and subsequent injuries to passengers or cabin crew members.
2007-26-16: We are adopting a new airworthiness directive (AD) for certain Cessna Model 680 airplanes. This AD requires inspecting the routing of the aft fairing wire bundle assembly for adequate separation between the wiring and the hydraulic line; inspecting for chafing or damage of the wire bundle assembly and for damage to the hydraulic line, and doing corrective actions if necessary. This AD results from an incident report which indicated that a hydraulic leak and wire chafing, including signs of heat damage, were found within the lower tail cone fairing area. Similar wire chafing has also been found on other airplanes. We are issuing this AD to detect and correct wire chafing, and inadequate separation of the wiring and hydraulic line, which could lead to electrical arcing and a hydraulic leak and could result in a potential source of ignition and consequent fire.
2020-03-24: The FAA is adopting a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate \n\n((Page 11290)) \n\nnew or more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
2001-12-09: This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Mystere-Falcon 900 and Falcon 900EX series airplanes, that requires replacement of the protective screens of the underfloor structure boxes at frame 25. This amendment is necessary to prevent water from collecting and freezing in the structure boxes at frame 25, which could result in jamming of the flight controls and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
96-24-17 R1: This document clarifies information in airworthiness directive (AD) 96-24-17, which applies to Don Luscombe Aviation History Foundation (Luscombe) Models 8, 8A, 8B, 8C, 8D, 8E, 8F, T-8F airplanes. AD 96-24-17 currently requires installing new inspection holes, modifying the wing tip fairings, and inspecting the wing spars for intergranular corrosion. The actions specified in AD 96-24-17 are intended to prevent wing spar failure from intergranular corrosion, which could result in structural failure of the wings and loss of control of the airplane. The AD was published with an Appendix providing an alternative method of compliance. Since issuance of AD 96-24-17, the FAA has re-examined the Appendix and has determined that clarification of certain inspections procedures is needed. This action clarifies the procedures specified in the Appendix of AD 96-24-17.
