2024-14-07: The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.

Applies to Models 206, U206, U206A, U206B, U206C, U206D, U206E, U206F, and U206G (R/Ns 206-0001 thru U20606065); P206, P206A, P206B, P206C, P206D, and P206E (S/Ns P206-0001 thru P20600647); 207 and 207A (S/Ns 20700001 thru 20700681); 210D, 210E, 210F, 210G, 210H, 210J, 210K, 210L, 210M, and 210N (S/Ns 21058221 thru 21064226) airplanes certificated in any category which are equipped with Continental Model IO-520-( ) engines. Compliance: Required within 100 hours time-in-service after the effective date of this AD and each 100 hours time-in-service thereafter, until modified in accordance with paragraph (b) of the AD. To eliminate the possibility of engine power reduction due to ingestion of pieces of a failed engine induction airbox outboard duct, accomplish the following: (a) Visually inspect the engine induction airbox outboard duct lower skin for cracks. (b) If cracks are found, prior to further flight, either replace theinduction airbox outboard duct with a Cessna Part Number 1250705-8 duct or repair the skin of the existing duct in accordance with the repair procedures of FAA Advisory Circulars AC 43.13-1A and AC 43.13-2A using material at least .040 inches thick. (c) An equivalent means of compliance with this AD may be used if approved by the Manager, Aircraft Certification Office, FAA, 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209. Cessna Single Engine Customer Care Service Information Letter SE84-20 dated November 2, 1984, covers the subject matter of this AD. This amendment becomes effective on June 20, 1985.
2024-13-07: The FAA is adopting a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a notice from a supplier reporting that torque wrenches used to install the air driven generator (ADG) downlock cam nut were out of calibration, which resulted in a higher torque level setting than required during the initial production installation of the affected cam nut. This AD requires replacement of the affected ADG locking cam screw and cam nut, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2016-25-20: We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model EC130B4, EC130T2, AS350B, AS350B1, AS350B2, AS350B3, AS350BA, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD requires inspecting each bi- directional suspension cross-bar (cross-bar). This AD was prompted by two reports of cracks in a cross-bar. These actions are intended to prevent the unsafe condition on these products.
2023-25-07: The FAA is superseding Airworthiness Directive (AD) 2023-04- 10, which applied to all Dassault Aviation Model MYSTERE-FALCON 900 airplanes. AD 2023-04-10 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2023-04- 10, and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive 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.
2016-25-28: We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS355NP helicopters. This AD requires removing and installing the fire extinguishing system pipes. This AD is prompted by the discovery that the left-hand and right-hand fire extinguishing discharge systems were incorrectly connected. The actions of this AD are intended to correct the unsafe condition on these products.
2016-25-21: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by reports of electrical shorts of the motor stator wiring burning a hole through the housing of the motor of the cabin air compressor (CAC). This AD requires installing modified inboard and outboard CAC modules on the left-hand (LH) side and right-hand (RH) side cabin air conditioning and temperature control system (CACTCS) packs. We are issuing this AD to prevent the unsafe condition on these products.
2016-25-16: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports of two cases where the main landing gear (MLG) failed to fully extend; it was determined that interference between the MLG door and the MLG fairing seal prevented the MLG door from opening fully. This AD requires repetitive inspections of the MLG fairing, fairing seal, door, and adjacent structures; and replacement or repair of affected parts and fasteners, or removal of the MLG door, if necessary. This AD also requires installation of a safety guide in the MLG fairing and an increase of the spacing between the MLG door and the fairing, which would terminate the repetitive inspections. We are issuing this AD to address the unsafe condition on these products.
