2016-20-12: We are superseding Airworthiness Directive (AD) 2012-20-07 for certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 2012-20-07 required revising the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness (ICA) to incorporate new limitations for fuel tank systems, and revising the maintenance program to incorporate revised fuel maintenance and inspection tasks. This new AD requires revising the maintenance or inspection program to incorporate revised fuel airworthiness limitations. This AD was prompted by Airbus issuing more restrictive maintenance requirements and/or airworthiness limitations. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
2015-10-03: We are superseding Airworthiness Directive (AD) 2014-09-05, for certain Airbus Model A330-200 and -300 series airplanes, and Model A340-200 and -300 series airplanes. AD 2014-09-05 required repetitive inspections of certain sidestay upper cardan pins of the main landing gear (MLG) and associated nuts and retainer assemblies, and pin replacement if necessary. This AD was prompted by a determination that a previously optional measurement is necessary to address the identified unsafe condition. This new AD continues to require a detailed inspection for visible chrome of each affected MLG sidestay upper cardan pin, associated nuts, and retainer assembly, and pin replacement if needed, and adds new requirements for measuring cardan pin clearance dimensions (gap check), doing corrective actions, and reporting all findings. We are issuing this AD to detect and correct migration of the sidestay upper cardan pin, which could result in disconnection of the sidestay upper arm from the airplane structure, and could result in a landing [[Page 30609]] gear collapse and consequent damage to the airplane and injury to occupants.
97-20-10 R1: This amendment revises an existing airworthiness directive (AD), applicable to certain de Havilland Model DHC-8-100, -200, and -300 series airplanes, that currently requires modification of the attitude and heading reference systems (AHRS). That action was prompted by a report of loss of power to both AHRS s during flight due to a faulty terminal block to which the signal ground for the AHRS s is connected. The actions specified by that AD are intended to prevent simultaneous power loss to both AHRS s, which could result in reduced controllability of the airplane. This amendment reduces the applicability of the existing AD.
98-07-23: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A340 series airplanes. This action requires revising the Airplane Flight Manual (AFM) to provide the flightcrew with procedures to prevent thrust loss during initial climb. This action also requires installing a new or modified electronic control unit on each engine, which, when accomplished, terminates the requirement for the AFM revision. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent significant thrust loss during initial climb, which could result in an increased risk of collision with obstacles in the initial climb path of the airplane.
2001-19-51: This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2001-19-51, which was sent previously to all known U.S. owners and operators of Eurocopter France (ECF) Model SA341G, SA342J, and SA-360C helicopters by individual letters. This AD requires, before further flight, replacing a certain unairworthy main rotor head torsion tie bar (tie bar) with an airworthy tie bar. This AD also requires revising the limitations section of the maintenance manual by adding a life limit for certain tie bars. This AD is prompted by an accident involving an ECF Model SA341G helicopter due to the failure of a tie bar. The actions specified by this AD are intended to prevent failure of a tie bar, loss of a main rotor blade, and subsequent loss of control of the helicopter.
2015-10-07: We are superseding airworthiness directive (AD) 2014-01-01 for all Turbomeca S.A. Arrius 2F turboshaft engines. AD 2014-01-01 required a one-time inspection of the ejector assembly nozzle of certain serial number (S/N) lubricating devices and, if a discrepancy was found, removal and replacement of the affected ejector assembly nozzle with a part eligible for installation. This AD requires the same action as AD 2014-01-01 and expands the list of affected S/N lubricating devices. This AD was prompted by the determination that additional lubricating devices, identifiable by S/N, may have an incorrect bonding of the nozzle on the ejector assembly. We are issuing this AD to prevent failure of the ejector assembly nozzle, which could lead to an in- flight shutdown (IFSD) of the engine, damage to the engine, and damage to the helicopter.
98-06-24: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires modification to reinforce the joints of certain fuselage frames. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent fatigue cracking of the fuselage frames, which could result in reduced structural integrity of the airplane.
97-15-12: This amendment adopts a new airworthiness directive (AD) that applies to certain Burkhart Grob, Luft-und Raumfahrt (Grob) Model G 109 sailplanes. This action requires installing a damper and new bell crank lever on the rudder, in addition to adjusting the weight and balance of the sailplane, to correct the tendency of flutter at specific excitation frequencies. For those Grob Model G 109 sailplanes that have previously accomplished this installation, a modification to the damper and bell crank lever, and adjustment to the weight and balance is required. These actions are prompted by the discovery of rudder vibration problems during testing of two Grob Model G 109 sailplanes. The actions specified by this AD are intended to prevent vibration of the rudder, which could result in structural damage and eventual loss of control of the sailplane.
2015-10-06: We are adopting a new airworthiness directive (AD) for certain Lycoming TIO-540-AJ1A reciprocating engines. This AD was prompted by several reports of cracked engine exhaust pipes. This AD requires inspection of the engine exhaust pipes for cracks and replacement of the turbocharger mounting bracket. We are issuing this AD to prevent failure of the exhaust system due to cracking, which could lead to uncontrolled engine fire, harmful exhaust gases entering the cabin resulting in crew incapacitation, and damage to the airplane.
