2004-20-10: The FAA adopts a new airworthiness directive (AD) for all Valentin GmbH & Co. Taifun 17E sailplanes. This AD requires you to do an operational check of the front wing-locking mechanism left and right, inspect stop key movement, inspect wing and fuselage side root ribs, inspect the wing side shear force fittings, and take any corrective actions that may be required. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect and correct malfunction of wing-locking mechanism, which could result in failure of the wing-locking mechanism disengagement. This failure could lead to unlocking of wing in flight and consequent loss of control of the sailplane.
2022-19-04: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-2C series airplanes. This AD was prompted by a report that insufficient clearance was found between the right stabilizer trim shut-off control wire (bundle W0589) and an elevator control cable. This AD requires a one-time inspection for insufficient clearance between the elevator control cable and wire bundle W0589 on the airplane's left crown, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
2013-17-03: We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 and -300 series airplanes; Model A340-200 and - 300 series airplanes; and Model A340-541 and -642 airplanes. This final rule was prompted by reports of wing tip brakes (WTBs) losing their braking function in service due to heavy wear on the brake discs. WTBs are designed to stop and hold the mechanical transmission of slats and flaps in certain failure cases. This final rule requires repetitive operational tests of certain WTB pressure-off-brakes (POBs) for performance on the flap and slat systems, and replacement of any affected WTB with a new or serviceable part if the test fails. This final rule also requires eventual replacement of all affected WTBs with a new part, which terminates the repetitive tests. We are issuing this final rule to prevent loss of the WTB braking function, and consequent inability of the flap or slat system to be stopped and held in [[Page 53636]] position during operation, which could result in loss of control of the airplane.
2004-20-14: This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Model A300 B4 series airplanes and all Airbus Model A300-600 series airplanes. That AD currently requires a one-time high frequency eddy current inspection to detect cracking of the splice fitting at fuselage frame (FR) 47 between stringers 24 and 25; and corrective actions if necessary. This amendment requires new repetitive inspections of an expanded area and adds airplanes to the applicability in the existing AD. The actions specified by this AD are intended to detect and correct cracking of the splice fitting at fuselage FR 47, which could result in reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
77-21-07: 77-21-07 MESSERSCHMITT-BOLKOW-BLOHM (MBB): Amendment 39-3061. Applies to Model BO-105A and BO-105C helicopters, Serial Number V4 through V10, and S1 through S160, certificated in all categories. Compliance required within the next 600 hours time in service after the effective date of this AD, unless already accomplished. Remove socket connections 1 VED and 1 VEE from main relay box, remove plugs 110 VVa and 210 VVa together with associated receptacles and wiring bundles, and install generator wiring assembly, in accordance with subparagraph 2B of MBB Service Bulletin No. 90-11 dated April 17, 1975, or an FAA-approved equivalent. This amendment becomes effective November 14, 1977.
2022-19-13: The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD was prompted by the identification of certain parts needing maintenance actions, including life limits and maintenance tasks. This AD requires incorporating into existing maintenance records requirements (airworthiness limitations), 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.
2022-20-06: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A320-251N, -253N, and -271N airplanes; and Model A321-251N, -253N, -271N, and -272N airplanes. This AD was prompted by the failure of an electronic centralized aircraft monitor (ECAM) warning to be triggered during heating of several sensing elements of the over-heat detection system (OHDS) loop sequentially during flight test operation procedures. This AD requires revising the existing airplane flight manual (AFM) with an AFM Temporary Revision (TR) to provide procedures to operate the airplane without functioning bleed leak detection; revising the operator's existing FAA-approved minimum equipment list (MEL); and modifying the electrical connections of the bleed monitoring computers (BMCs), which allows for the removal of the AFM TR and the MEL revision; 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.
2022-19-01: The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-2B67/P model turbofan engines. This AD was prompted by the detection of an iron inclusion in a forging, which may reduce the fatigue life of certain low-pressure turbine rotor (LPTR) stage 4 disks and LPTR stage 6 disks. This AD requires the removal of certain LPTR stage 4 disks and LPTR stage 6 disks from service and replacement with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
2004-20-11: The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300 B2 and B4 series airplanes; and certain Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes; and Model C4-605R Variant F airplanes (collectively called A300-600). This AD requires an inspection of the skin panels of the wing slats for damage and certain repairs, and applicable related investigative/corrective actions if necessary. This AD is prompted by the results of an engineering evaluation that revealed that several repairs and some allowable damage limits specified in the structural repair manuals do not provide adequate static and/or fatigue strength for repaired wing slats. We are issuing this AD to find and fix previously done repairs of the wing slats that have inadequate static and/or fatigue strength, which, if not corrected, could result in loss of the slats and consequent reduced controllability of the airplane.
2013-16-22: We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. This AD was prompted by reports of chafing between the auxiliary power unit (APU) electronic starter controller (ESC) power cables and the airplane tail cone firewall. This AD requires a detailed inspection for damage to the insulation and inner conductors of the APU ESC power cables, installing a new grommet support in the tail cone firewall, and corrective actions if necessary. We are issuing this AD to detect and correct damage to the APU ESC power cable harness, which if not corrected, could result in reduced structural integrity of the fuselage and empennage in the event of fire penetration through the firewall.
