2021-11-14: The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW169 helicopters. This AD was prompted by reports of failed nose landing gear (NLG) retraction actuators during the acceptance test procedures on the ground on the final assembly line. This AD requires depending on the helicopter configuration, various modifications, installation checks, inspections of the NLG and main landing gear (MLG) retraction actuators and of the plungers of the NLG and MLG up down lock actuators, and corrective actions if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
2004-05-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319 and A320 series airplanes, that requires an inspection of the clearance space between the fuel quantity indication (FQI) probes located in the center fuel tank and the adjacent structure, an inspection of the position of the support bracket for each probe, an inspection of the part number for each support bracket, and corrective action if necessary. The actions specified by this AD are intended to prevent the loss of FQI of the center fuel tank, and electrical arcing between the FQI probes and the adjacent structure in the event that the airplane is struck by lightning. Such arcing could create a potential ignition source within the center fuel tank and an increased risk of a fuel tank explosion and fire. This action is intended to address the identified unsafe condition.
2021-11-11: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 Freighter series airplanes. This AD was prompted by a report indicating occurrences of broken brackets of the support structure of the halon fire extinguishing bottle 4005WX; investigation showed that fatigue cracks initiated in the attachment brackets at the cross beams due to dynamic loading, and in some cases propagated in the struts. This AD requires replacing the support brackets of the 4005WX fire extinguisher bottle with reinforced support brackets, and replacing the strut assembly at the affected location, 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.
46-46-02: 46-46-02\tNORTH AMERICAN: Was Mandatory Note 6 of AD-2-575-3.) Applies to Army BC-1A, AT-6, -6A, -6B, -6C; Navy SNJ-2, -3, -4 Aircraft.\n \n\tTo be accomplished prior to January 1, 1947. \n\n\tInspect all airplanes having Vest Two-Place Chum Seats installed prior to October 9, 1946, to determine that an elevator rear stop is installed on the horizontal stabilizer rear spar directly in front of the elevator horn and that the modification incorporates revised self-aligning rudder balance brackets, rudder balance cable, rudder pedal adjustment bar and reinforcement plates on forward side of firewall at the balance pulley bracket attachment points in accordance with Vest Installation Instructions dated October 9, 1946.
2004-05-06: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10-10, DC-10-10F, DC- 10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F airplanes; and Model MD-11 and MD-11F airplanes. This amendment requires replacement of the left and right number one passenger door bolted lower seal-to-retainer and girt bar view window assemblies with new, double-flush riveted assemblies. This action is necessary to prevent the number one passenger door slide from inflating before it has cleared the slide cover, which could result in the slide being unusable during an emergency evacuation and consequent injury to passengers or airplane crewmembers. This action is intended to address the identified unsafe condition.
2010-26-54: We are adopting a new airworthiness directive (AD) for the products listed above. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires obtaining written approval from the Manager, Wichita Aircraft Certification Office (ACO), to operate the airplane. This written approval must clearly state that operation is approved per Emergency AD 2010-26-54. This AD was prompted by a Cessna Model LC41-550FG airplane that suffered a significant structural failure in the wing during a production acceptance flight test. We are issuing this AD to prevent catastrophic failure of the wing due to disbonding of the wing skin from the wing spar.
2021-10-21: The FAA is superseding Airworthiness Directive (AD) 2019-07-07 for various Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK117 and Model BO-105 helicopters. AD 2019-07-07 required removing certain part numbered swashplate bellows (bellows) from service, cleaning and inspecting certain parts, and depending on the inspection results removing certain parts from service, applying torque, and repetitively inspecting the swashplate assembly (swashplate). This AD retains certain requirements of AD 2019-07-07, expands the installation prohibition, adds additional inspections, and updates the applicable service information. The FAA is issuing this AD to address an unsafe condition on these products.
2004-05-02: The FAA adopts a new airworthiness directive (AD) for all AeroSpace Technologies of Australia Pty Ltd. (ASTA) Models N22B, N22S, and N24A airplanes. This AD requires you to repetitively inspect wing fittings for fatigue defects, replace or correct defective wing fittings, and replace the stub wing front spar assembly and wing fitting when fatigue life limits are reached. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Australia. We are issuing this AD to detect and correct defects in the wing strut upper end fittings, wing strut lower end fittings, stub wing strut pick up fittings, and the stub wing front spar assembly. These defects could result in failure of the fittings or spar assembly and lead to reduced structural capability or reduced controllability of the airplane.
67-14-05: 67-14-05 BRITISH AIRCRAFT: Amdt. 39-398 Part 39 Federal Register April 14, 1967. Applies to Model BAC 1-11 200 Series Airplanes. Compliance required as indicated. To prevent fatigue failure of the nose landing gear steering jack cylinder gland nut, accomplish the following: (a) Replace aluminum alloy gland nuts P/N AB44-229 having less than 4,900 hours' time in service on the effective date of this AD with unused aluminum alloy gland nuts of the same part number or with steel gland nuts P/N AB44-1793, before the accumulation of 5,000 hours' time in service. (b) Replace aluminum alloy gland nuts P/N AB44-229 having 4,900 or more hours' time in service on the effective date of this AD with unused aluminum alloy gland nuts having the same part number or with steel gland nuts P/N AB44-1793, within the next 100 hours' time in service. (c) Aluminum alloy gland nuts P/N AB44-229 installed as replacement parts in complying with either (a) or (b) must be replaced before the accumulation of 5,000 hours' time in service. (British Aircraft Corporation (BAC) One-Eleven Alert Service Bulletin 32-A-PM 2496 pertains to this subject.) This directive effective May 14, 1967.
2004-05-08: This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9-31 and DC-9-32 airplanes, that requires replacement of certain power relays, and subsequent repetitive cleaning, inspecting, repairing, and testing of certain replaced power relays. This action is necessary to prevent internal arcing of the left and right generator power relays, auxiliary power relays, and external power relays, and consequent smoke and/or fire in the cockpit and cabin. This action is intended to address the identified unsafe condition.
