95-11-15 R1: This action confirms the effective date of Airworthiness Directive (AD) 95-11-15 R1, which applies to Alexander Schleicher Segelflugzeugbau (Alexander Schleicher) Model ASK 21 gliders. AD 95-11-15 R1 requires replacing the parallel rocker with a part of improved design and incorporating flight manual revisions, but only for those gliders with the automatic elevator connection incorporated. AD 95-11-15 was the result of two incidents of the parallel rocker breaking at the elevator connection on the affected gliders. Since that time, the FAA has determined that the AD should only affect those Model ASK 21 gliders equipped with the automatic elevator connection. The actions specified in this AD are intended to continue to prevent possible loss of elevator control that could result from a broken parallel rocker.
60-08-02: 60-08-02 BOEING: Amdt. 131 Part 507 Federal Register April 9, 1960. Applies to All Model 75 Series Aircraft Operated in Restricted Category With a Gross Weight Exceeding 3,200 Pounds. Compliance required not later than June 1, 1960, and at each 100 hours' time in service thereafter. Due to reports of cracked longerons, the following shall be accomplished: Visually inspect the fuselage longerons and fuselage diagonal bracing for cracks in the vicinity of the lower wing front spar attach fittings. All cracked structural members shall be repaired or replaced in accordance with CAR 18.
2002-01-20: This amendment adopts a new airworthiness directive (AD), applicable to certain BAE Systems (Operations) Limited Model BAe 146- 200A series airplanes, that requires replacement of the signal summing units (SSUs) for the stall identification system with new, improved parts. The actions specified by this AD are intended to prevent stall identification and stall warning signals from occurring at the same time, leading the flight crew to take action based on erroneous information, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
99-13-04: This amendment adopts a new airworthiness directive (AD) that applies to certain Cessna Aircraft Company (Cessna) Models 206H and T206H airplanes. This AD requires inspecting the left and right wing aileron control bellcrank stop bolts and lock nuts for flush and tight contact with the surface of the threaded boss on each end of the yoke assemblies, and accomplishing follow-on and corrective actions, as applicable. This AD is the result of an inspection on one of the affected airplanes that showed that the aileron control bellcrank stop bolt had partially backed out of the threaded boss. The actions specified by this AD are intended to detect and correct loose aileron control bellcrank stop bolts, which could result in restricted movement of the ailerons with possible partial or complete loss of aileron control.
99-12-06: This amendment adopts a new airworthiness directive (AD) that requires replacing certain AlliedSignal Inc. VN 411B VHF navigation receivers installed on aircraft if the receivers do not have Modification 21 incorporated. This AD is the result of a report of navigation receiver interference during landing operations. The actions specified by this AD are intended to prevent VHF navigation receiver interference from frequency modulation (FM) radio station broadcasts, which could cause distortion of the navigation audio and deflection of the desired flight path of the airplane during landing operations with possible loss of control of the airplane.
2019-23-14: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by significant changes made to the airworthiness limitations (AWLs) related to fuel tank ignition prevention and the nitrogen generation system. This AD requires revising the existing maintenance or inspection program, as applicable, to include new or revised AWLs. The FAA is issuing this AD to address the unsafe condition on these products.
2006-05-10: The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ airplanes. This AD requires a one-time detailed inspection for corrosion of the hinge bracket assembly of the left and right main landing gear (MLG) doors, and corrective action if necessary. This AD results from in-service reports of hinge bracket failures on the MLG doors. We are issuing this AD to prevent failure of the hinge bracket on the MLG door, which could result in separation of the door, consequent structural damage to the airplane, and possible injury to people on the ground.
2019-25-19: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 airplanes. This AD was prompted by a report of dislodged passenger door girt bars. This AD requires modification of the girt bar retention mechanism of the affected doors, 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.
2019-24-01: The FAA is adopting a new airworthiness directive (AD) for Airbus SAS Model A318 and A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes; Model A330-200 and A330-200 Freighter series airplanes; Model A340-200 and -300 series airplanes; and Model A340-500 and -600 airplanes (except for airplanes equipped with flammability reduction means (FRM) approved by the FAA as compliant with the Fuel Tank Flammability Reduction (FTFR) rule). This AD was prompted by the FAA's analysis of the fuel system reviews on these models conducted by the manufacturer. This AD requires modifying the fuel quantity indicating system (FQIS) to prevent development of an ignition source inside the center fuel tank due to electrical fault conditions. This AD also provides alternative actions for cargo airplanes. This AD does not apply to airplanes equipped with FRM approved by the FAA. The FAA is issuing this AD to address the unsafe condition on these products.
2006-05-08: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 series airplanes. This AD requires installing a new washer between the lower wing surface and the jam nut of the sump drain valve assembly. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent energy from a lightning strike on the bushing for the sump drain valve from arcing to the inside of the center fuel tank wall, which could create an ignition source in the fuel tank and result in a fuel tank explosion.
