2001-14-16: This amendment adopts a new airworthiness directive (AD), applicable to certain Gulfstream Model G-V series airplanes, that requires repetitively replacing the existing nose wheel steering actuator with a new or reworked actuator having the same part number. The actions specified by this AD are intended to prevent loss of nose wheel steering control without a corresponding alert message annunciation due to the effects of moisture intrusion into the rotary variable displacement transducer (RVDT) inside the steering actuator, and consequently, an over steering condition. If an over steering condition were to occur during landing, the airplane could depart the runway. This action is intended to address the identified unsafe condition.
94-24-10: This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB SF340A and SAAB 340B airplanes, that requires repetitive inspections to detect cracking of the tray stop spindle and backrest spindle bosses on the inboard sections of certain seats; and replacement of the inboard sections, if necessary. This amendment also requires repair and identification of the modification plate, which would terminate the requirement to inspect repetitively. This amendment is prompted by reports of fatigue cracking in the vicinity of the tray stop spindle and backrest spindle bosses, which could lead to excessive movement and eventual failure of the backrest on these seats during aft loading. The actions specified by this AD are intended to prevent failure of the backrest on these seats, which could inhibit emergency egress.
2008-06-08: 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: Cracking has been found on the centre fuselage top aft longeron at Rib `0' on an in-service aircraft. * * * This condition could result in reduced structural integrity of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2001-14-04: This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 767-300 series airplanes modified by Supplemental Type Certificate ST00118SE, that requires modification of the in-flight entertainment (IFE) system and revision of the Airplane Flight Manual. This action is necessary to ensure that the flight crew is able to remove electrical power from the IFE system when necessary and is advised of appropriate procedures for such action. Inability to remove power from the IFE system during a non-normal or emergency situation could result in inability to control smoke or fumes in the airplane flight deck or cabin. This action is intended to address the identified unsafe condition.
2020-10-04: The FAA is adopting a new airworthiness directive (AD) for all General Electric Company (GE) GE90-110B1 and GE90-115B model turbofan engines with a certain interstage high-pressure turbine (HPT) rotor seal installed. This AD requires initial and repetitive ultrasonic inspections (USIs) of the interstage HPT rotor seal and, depending on the results of the inspection, replacement of the interstage HPT rotor seal with a part eligible for installation. This AD also requires the removal of the interstage HPT rotor seal at the next engine shop visit. This AD was prompted by investigative findings from an event involving an uncontained interstage HPT rotor seal failure that resulted in debris penetrating the fuselage and the other engine. The FAA is issuing this AD to address the unsafe condition on these products.
2001-14-06: This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 737-300, -400, and -500 series airplanes, that requires repetitive inspections of certain connectors located in the main wheel wells to detect discrepancies; and corrective action, if necessary. This amendment is prompted by reports indicating engine shutdown during flight due to uncommanded movement of the engine shutoff valve. These actions are necessary to detect and correct discrepancies of certain connectors located in the main wheel wells, which could result in electrical arcing of the connectors, uncommanded closure of the engine fuel shut-off valves, and consequent in-flight loss of thrust or engine shutdown from lack of fuel.
2018-18-05: We are adopting a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes. This AD was prompted by a determination that more restrictive maintenance instructions and airworthiness limitations are necessary. This AD requires updating the maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance requirements and airworthiness limitations. We are issuing this AD to address the unsafe condition on these products.
2018-16-14: We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron Inc. (Bell) Model 212, Model 412, and Model 412EP helicopters. This AD requires replacing the emergency flotation system (EFS) tube assembly. This AD was prompted by a report of an EFS tube assembly failure. The actions of this AD are intended to address an unsafe condition on these products.
2018-18-04: We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report of protective caps that were not removed from fire extinguishing lines in certain areas of the engines. This AD requires an inspection for the presence of protective caps on fire extinguishing lines, and corrective action. We are issuing this AD to address the unsafe condition on these products.
94-23-04: This amendment adopts a new airworthiness directive (AD), applicable to Garrett Turbine Engine Company ATF3 series turbofan engines, that requires a one-time inspection for cracks of the curvic and bore area of the high pressure turbine (HPT) rotor assembly disk, and replacement, if necessary, with a serviceable disk. This amendment is prompted by several reports of cracks discovered during routine inspections of HPT rotor assembly disks. The actions specified by this AD are intended to prevent an uncontained failure of the HPT rotor assembly disk.
