2008-01-03: The FAA is adopting a new airworthiness directive (AD) for certain Learjet Model 45 airplanes. This AD requires revising the Airworthiness Limitations section of the airplane maintenance manual to incorporate certain inspections and compliance times to detect fatigue cracking of certain principal structural elements (PSEs). This AD results from new and more restrictive life limits and inspection intervals for certain PSEs. We are issuing this AD to ensure that fatigue cracking of various PSEs is detected and corrected; such fatigue cracking could adversely affect the structural integrity of these airplanes.
2001-12-14: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 series airplanes, that requires an inspection to detect miswiring of diodes in the heating system of the pitot static probes, and corrective action, if necessary. The actions specified by this AD are intended to prevent reduced power to the heating system of the pitot static probes, leading to ice accumulation on the pitot static probes, which could result in erroneous airspeed or altitude indications to the flight crew, and consequent reduced operational safety in all phases of flight. This action is intended to address the identified unsafe condition.
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.
