95-21-06: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires replacement of the fire extinguisher distribution pipe and attachments in the lower deck cargo compartment fire extinguishing system. This amendment is prompted by a report indicating that, in response to a smoke warning in the forward cargo compartment on one airplane, bottle 2 of the fire extinguishing system did not discharge extinguishing agent into the cargo compartment due to a blockage of the discharge pipe by debris within it. The actions specified in this AD are intended to ensure that, in the event of a fire, adequate fire extinguishing agent is discharged into the cargo compartment.
2023-21-08: The FAA is superseding Airworthiness Directive (AD) 2021-21-13 for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000 engines. AD 2021-21-13 required the operator to revise the airworthiness limitation section (ALS) of their existing approved aircraft maintenance program (AMP) by incorporating the revised tasks of the applicable time limits manual (TLM) for each affected model engine. Since the FAA issued AD 2021-21-13, the manufacturer has revised the TLM, introducing new and more restrictive instructions. This AD is prompted by the manufacturer revising the engine TLM life limits of certain critical rotating parts. This AD requires revisions to the ALS of the operator's existing approved AMP, 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.
2023-22-11: The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. (Embraer) Model EMB-505 airplanes. This AD was prompted by an occurrence of corrosion on the clutch retaining bolt of the aileron autopilot servo mount. This AD requires repetitively replacing the clutch retaining bolt and washer of the aileron autopilot servo mount, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
97-07-03: This amendment supersedes Airworthiness Directive (AD) 81-11-04 that applies to The New Piper Aircraft, Inc. (Piper) Models PA31, PA31-300, PA31-325, and PA31-350 airplanes that have Cleveland nose wheel assembly part number (P/N) 40-76B installed. AD 81-11-04 currently requires inspecting the nose wheel flange for cracks. The repetitive inspections terminate by replacing the nose wheel assembly with Cleveland P/N 40-140, which is an improved design. This action is prompted by the lack of designation of Piper Model PA31P in the Applicability section of AD 81-11-04, and the subsequent failure of a nose wheel assembly on a Piper Model PA31P airplane during taxiing operations. The actions specified by this AD are intended to prevent the failure of the nose wheel, which if not corrected, could result in loss of control of the airplane during taxiing, take-off, or landing operations.
76-20-08: 76-20-08 LOCKHEED-CALIFORNIA COMPANY: Amendment 39-2742 as amended by Amendment 39-2916. Applies to Model L-1011-385 series airplanes, certificated in all categories. Compliance required as indicated. To prevent possible collapse of a main landing gear assembly due to failure of one or both of the two main landing gear upper side brace spherical bearing trunnion retaining bolts, accomplish the following: (a) Within the next 75 hours' time in service after the effective date of this AD accomplish the following checks, inspections, repairs or replacements as necessary, in accordance with accomplishment instructions of the Lockheed-California Company Alert Service Bulletin 093- 32-A115, dated September 1, 1976, or later FAA-approved revisions. (1) Prior to each flight, perform a visual check of each main landing gear upper side brace trunnion joint and verify that the two trunnion bearing cap retaining bolts P/Ns 76754-18-71 or 69680v18-71 or 69680-18-71 are in place and that no obvious structural deformation of the trunnion bearing caps P/Ns 1504393-109 or -110 has occurred. (2) If one or both retaining bolts P/Ns 76754-18-71 or 69680v18-71 or 69680-18-71 are missing or if a structural deformation of the trunnion bearing caps P/Ns 1504393-109 or -110 appears to have occurred, before further flight replace both retaining bolts and inspect the side brace support fitting P/Ns 1504393-107 or -108 and the trunnion bearing caps P/Ns 1504393-109 or -110 for structural damage and replace or repair as necessary the parts found to be damaged. (3) The checks required by this AD may be performed by a flight crew member. (b) Equivalent checks, inspections, repairs and replacements may be used when approved by the Chief, Aircraft Engineering Division, FAA, Western Region. (c) Compliance is required on or before March 31, 1978, unless already accomplished: Accomplish the modification of the main landing gear upper side brace trunnion jointsin accordance with Paragraph 2, Accomplishment Instructions, of the FAA approved Lockheed-California Company Service Bulletin 093-32-115, Revision I, dated March 18, 1977 or later FAA approved revisions. (d) Accomplishment of the modification of the upper side brace trunnion joints in accordance with paragraph (c) will remove the need for accomplishment of the requirements of paragraph (a). Amendment 39-2742 became effective October 18, 1976. This amendment 39-2916 becomes effective June 17, 1977.
2005-05-04: The FAA is adopting a new airworthiness directive (AD) for all Aerospatiale Model ATR 42-200, -300, and -320 series airplanes. This AD requires inspecting to determine the part and serial number of the swinging lever of the main landing gears (MLG) and replacing the swinging lever if necessary. This AD is prompted by a report that, on an airplane lined up for takeoff, the swinging lever of the left MLG collapsed when engine power was applied. We are issuing this AD to prevent fracture of the MLG swinging lever, which could result in collapse of the swinging lever and reduced structural integrity and possible collapse of the MLG during operations on the ground.
2023-21-09: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 777-200, 777-200LR, 777-300, 777-300ER, and 777F series airplanes. This AD was prompted by a report of a ''FLAPS DRIVE'' caution message in flight due to the torque trip indicator of the No. 2 trailing edge (TE) flap transmission assembly being in the set position, which resulted in an air turn-back. This AD requires an inspection or records review to determine the serial numbers of the TE flap transmission and gearbox assemblies, and applicable on-condition corrective actions. This AD also limits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
95-19-02: This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F28 Mark 0100 series airplanes, that requires replacement of the flight control lock (FCL) handle and switch with a modified unit. This amendment is prompted by a report of sudden engagement of the FCL system during approach for landing. The actions specified by this AD are intended to prevent inadvertent engagement of the FCL system during flight and subsequent reduced controllability of the airplane.
2005-05-01: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757 series airplanes. This AD requires identification of the part number for the cable assembly for the lower anti-collision light, and related \ninvestigative and corrective actions if necessary. This AD is prompted by a report of damage caused by an electrical arc in a connector on the cable assembly for the lower anti-collision light. We are issuing this AD to prevent an electrical arc in the cable assembly for the lower anti-collision light, which could result in a fire in a flammable leakage zone of the airplane.
2015-02-25: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by fuel system reviews conducted by the manufacturer. This AD requires replacing a fitting that is part of the refuel control solenoid valve assembly. 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 fuel tank explosions and consequent loss of the airplane.
