Box 3707, Seattle, Washington 98124, or they may be examined at the FAA, Northwest Mountain Region, 9010 East Marginal Way South, Seattle, Washington 98108. \n\n\tThis amendment becomes effective January 25, 1985.
2024-10-11: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by a report indicating that the rigging pin in the bulkhead internal crank assembly of the overwing emergency exit door (OWEED) escape slide mechanism was not removed during production. This AD requires inspecting the OWEED escape slide mechanism to determine if a rigging pin is installed and, if installed, removing the rigging pin, as specified in Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2004-05-07: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that currently requires a one-time inspection to detect abrasion damage and installation discrepancies of the wire bundles located below the P37 panel, and corrective action if necessary. For airplanes already subject to the existing AD, this amendment requires inspecting to determine whether the existing location of a certain wire support standoff is adequate, relocating the wire support standoff if necessary, installing protective sleeving over the wire bundles, and installing wire bundle support clamps if necessary. This amendment also expands the applicability of the existing AD to include additional airplanes, and require inspecting the sleeving on certain wire bundles, and accomplishing corrective action if necessary, on those airplanes. The actions specified by this AD are intended to detect and prevent abrasion damage and correct installation discrepancies of the wire bundles located below the P37 panel, which could result in arcing to structure and consequent fire or loss of function of affected systems. This action is intended to address the identified unsafe condition.
2001-09-10: This amendment supersedes an existing airworthiness directive (AD), applicable to all McDonnell Douglas Model MD-11 series airplanes equipped with Pratt & Whitney Model PW4400 series engines, that currently requires revising the Airplane Flight Manual (AFM) to advise the flight crew of applicable operational limits. This amendment corrects a typographical error in one paragraph of the existing AD that resulted in a reference to an incorrect engine fan blade which is not subject to the requirements of that paragraph. The actions specified in this AD are intended to ensure that the flight crew is informed of applicable limitations in airplane performance, and to prevent reduced acceleration and climb performance relative to performance data in the AFM, which could result in the airplane overrunning the end of the runway during takeoff or landing, or impacting obstacles or terrain. This action is intended to address the identified unsafe condition.
2024-10-05: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. This AD was prompted by reports of operators finding frequent and severe damage to the blowout vent grilles throughout the lower lobe cargo compartment. This AD requires repetitive detailed inspections of certain decompression panels and pressure equalization valves, as applicable, in the forward and aft lower lobe cargo compartments for damage, and applicable on- condition actions. For certain airplanes, this AD also requires installation of decompression panels with billet grilles. For other certain airplanes, this AD also requires replacement of a certain soft bulkhead with a rigid bulkhead. For certain other airplanes, this AD requires installation of doublers to a certain bulkhead assembly panel. The FAA is issuing this AD to address the unsafe condition on these products.

2005-08-12: The FAA adopts a new airworthiness directive (AD) for certain CENTRAIR 101 series gliders. This AD requires you to replace non- strengthened rudder pedals with reinforced rudder pedals. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. We are issuing this AD to replace the non-strengthened rudder pedals and to prevent failure of the rudder controls. This failure could lead to loss of directional control of the glider.
2024-11-03: The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines, AG (IAE AG) Model V2500 engines. This AD was prompted by an analysis of an event involving an International Aero Engines, LLC (IAE LLC) Model PW1127GA-JM engine, which experienced a high-pressure compressor (HPC) 7th-stage integrally bladed rotor (IBR-7) separation that resulted in an aborted takeoff. This AD requires performing an angled ultrasonic inspection (AUSI) of certain high-pressure turbine (HPT) 1st-stage hubs and HPT 2nd-stage hubs for cracks and replacing if necessary. This AD also requires accelerated replacement of certain HPT 1st-stage hubs and HPT 2nd-stage hubs. The FAA is issuing this AD to address the unsafe condition on these products.
2024-08-09: The FAA is adopting a new airworthiness directive (AD) for certain GA8 Airvan (Pty) Ltd Model GA8 and GA8-TC320 airplanes. This AD is prompted by reports of insufficient electrical bonding of the solenoid (relay) box assembly that could result in degraded performance, errors, or intermittent failures of equipment connected to electrical Bus 1, Bus 2, associated electrical control, and protective devices fitted within or attached to the solenoid box. This AD requires inspecting for an existing wire connecting the relay box earth point to the ground power socket, and if one is not present, installing a mechanical connection. The FAA is issuing this AD to address the unsafe condition on these products.
