2020-14-06: The FAA is adopting a new airworthiness directive (AD) for Diamond Aircraft Industries Models DA 40, DA 40 F, and DA 40 NG airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as deterioration of the fuel tank \nconnection hoses that could result in restriction of fuel flow leading to fuel starvation and reduced control of the airplane. The FAA is issuing this AD to require actions to address the unsafe condition on these products.

94-05-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 727 series airplanes, that requires incorporation of certain structural modifications. This amendment is prompted by an evaluation by the Model 727 Structures Working Group, comprised of aircraft operators, manufacturers, and the FAA. This Working Group evaluated Boeing service bulletins that must be included as part of the "Aging Airplane Structural Modification Program." The actions specified by this AD are intended to prevent degradation in the structural capabilities of the affected airplanes. The actions also reflect the FAA's decision that long term continued operational safety should be assured by actual modification of the airframe rather than repetitive inspections.

Compliance is required as indicated unless previously accomplished. To prevent failure of the engine fuel feed hose and engine flame out or engine nacelle fire, accomplish the following: \n\n\tA.\tWithin the next 200 landings or 30 days, whichever occurs first, after the effective date of this AD, and thereafter at intervals not to exceed 200 landings, inspect and replace, as necessary, the engine fuel feed hose in accordance with Boeing Service Bulletin 767-73-11 dated March 28, 1984, or later FAA approved revision. \n\n\tNOTE: It is anticipated that this AD will be amended when a new reinforced hose or equivalent terminating action is available. \n\n\tB.\tAlternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region. \n\n\tC.\tFor the purpose of this AD, and when approved by an FAA maintenance inspector, the number of landings may be computed by dividing each airplane's time in service by the operator's fleet average time from takeoff to landing for the aircraft type. \n\n\tD.\tSpecial flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD. \n\n\tE.\tInstallation of fuel feed hose P/N S332TO12-11 in accordance with Service Bulletin 767-73-11, Revision 2, dated May 25, 1984, or later FAA-approved revisions, terminates the repetitive inspection requirement of paragraph A., above. \n\n\tAmendment 39-4873 became effective June 4, 1984. \n\tAmendment 39-4979 became effective January 24, 1985. \n\tThis amendment 39-5117becomes effective September 16, 1985.
2003-18-09: The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce plc (RR) Trent 768-60, Trent 772-60, and Trent 772B-60 turbofan engines. This AD requires removal from service of certain part numbers of high pressure (HP) compressor rotor shafts, based on a newly established reduced life limit. This AD is prompted by reports of HP compressor drums with small cracks in blade loading slots found at overhaul inspection. The HP compressor drums are an integral part of the HP compressor rotor shaft. We are issuing this AD to prevent possible uncontained HP compressor drum failure, which could result in damage to the airplane.
