2023-02-13: The FAA is superseding Airworthiness Directive (AD) 2020-21- 19, which applied to certain Dassault Aviation Model FALCON 900EX airplanes. AD 2020-21-19 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 2020-21-19, and also requires revising the existing maintenance or inspection program, as applicable, to incorporate additional 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.
72-24-05: 72-24-05 MCDONNELL DOUGLAS: Amdt. 39-1566. Applies to Model DC-9-10 series airplanes certificated in all categories. \n\n\tCompliance required within the next 3,000 hours' time in service after the effective date of this AD, unless already accomplished. \n\n\tTo prevent possible injury to the forward flight attendant, remove the entry door closing assist handle, P/N 3918664-1, and install a handle, P/N 3924268-1, per McDonnell Douglas Service Bulletin No. 25-31, dated May 4, 1966, or McDonnell Douglas Service Bulletin No. 25-185, dated March 31, 1972, or later FAA-approved revisions, or an equivalent modification approved by the Chief, Aircraft Engineering Division, FAA, Western Region. \n\n\tThis amendment becomes effective January 3, 1973.
95-26-05 R1: This amendment rescinds an existing Airworthiness Directive (AD) for Robinson Helicopter Company (Robinson) Model R44 helicopters, which currently requires revisions to the R44 Rotorcraft Flight Manual (RFM). The RFM revisions limit operations in high winds and turbulence. The RFM revisions also provide information about main rotor stall and mast bumping with recommendations for avoiding these situations and additional emergency procedures for use in certain conditions. This amendment is prompted by the FAA's determination that the limitations and the procedures required by that AD are no longer necessary to correct an unsafe condition. The actions specified by this AD rescind all the requirements of AD 95-26-05, Amendment 39-9463, Docket 95-SW- 30-AD.
2004-12-14: This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires an inspection of the alternating current (AC) power cables, realignment of the AC power cable retaining clamp, and corrective actions if necessary. This action is necessary to prevent chafing of the AC power cables against the alternator, which could result in a short circuit and impaired performance of AC-powered components, possibly leading to loss of flight-critical information to the flight deck and reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
88-12-12: 88-12-12 CESSNA: Amendment 39-5941. Applies to all serial numbers of Models 177RG and F177RG airplanes certificated in any category. \n\n\tCompliance: Required within the next 75 hours time in service after the effective date of this AD, unless already accomplished. \n\n\tTo prevent power loss or engine stoppage due to water contamination of the fuel system, accomplish the following: \n\n\t(a)\tModify the airplane fuel system using one of the options in subparagraphs (a)(1), (a)(2), or (a)(3) below: \n\n\t\t(1)\tInstall a fuel strainer quick drain control in accordance with STC SA2344CE or SA2345CE. \n\tNOTE 1: These STCs are owned by Air Plains, Inc., P.O. Box 541, Wellington, Kansas 67152, telephone (316) 326-8581. \n\n\t\t(2)\tInstall a fuel strainer quick drain control in accordance with STC SA2335CE or SA2336CE. \n\tNOTE 2: These STCs are owned by Cessna Pilots Association, Inc., Wichita Mid- Continent Airport, 2120 Airport Road, P.O. Box 12948, Wichita, Kansas 67277, telephone (316)946-4777. \n\n\t\t(3)\tInstall a fuel strainer quick drain control by using equivalent aircraft standard hardware. \n\tNOTE 3: The FAA has received reports of corrosion inside the fuel strainer bowl caused by undrained water. A check of the condition of the fuel strainer and bowl can be made during installation of the fuel strainer quick drain control. \n\n\t(b)\tAirplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished. \n\n\t(c)\tAn equivalent means of compliance with this AD may be used, if approved by the Manager, Wichita Aircraft Certification Office, Federal Aviation Administration, 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209. \n\n\tAll persons affected by this AD may obtain copies of the document(s) referred to herein upon request to: Cessna Pilots Association Supplemental Type Certificates (STCs) SA2335CE and SA2336CE information may be obtained from Mr. John Frank, Editor Cessna Pilots Association, Wichita Mid-Continent Airport, 2120 Airport Road, P.O.

2022-14-06: 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 incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
