2007-11-04: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: This AD is issued following reports, on several aircraft, of important corrosion found on the ailerons bearings. This condition, if left uncorrected, could result in the loss of the roll control on the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
2005-26-10: The FAA is adopting a new airworthiness directive (AD) for Lycoming Engines (formerly Textron Lycoming) models 320, 360, and 540 series, "Parallel Valve" reciprocating engines, with certain Engine Components Inc. (ECi) cylinder assemblies, part number (P/N) AEL65102 series "Classic Cast", installed. This AD requires replacing these ECi cylinder assemblies. This AD results from reports of about 30 failures of the subject cylinder assemblies marketed by ECi. We are issuing this AD to prevent loss of engine power due to cracks in the cylinder assemblies and possible engine failure caused by separation of a cylinder head.
87-21-07 R1: 87-21-07 R1 GULFSTREAM (AERO COMMANDER): Amendment 39-5741 as revised by Amendment 39-6182. Applicability: Models 500, 500A, 500B, 500U, 520, 560, 560A, 560E, 560F, 680, 680E, 680F, 680F(P), 680FL(P), and 720 Serial Numbers (S/N 1 through 1854); and Models 500S (S/N 1755 through 3323), 680FL (S/N 1261 through 1853), 685 (S/N 12001 through 12066), and 700 (S/N 70001 through 70032) airplanes equipped with reciprocating engines, certificated in any category. Compliance: Required as indicated unless already accomplished. To preclude misfueling of the airplane resulting in engine failure, accomplish the following: (a) Within the next 12 calendar months after the effective date of this revised AD, unless already accomplished in accordance with the requirements of AD 87-21-07 effective November 12, 1987, modify all fuel filler opening(s) in accordance with the applicable instructions contained in Gulfstream Service Information No. SI-209A, dated June 7, 1988.NOTE: AD 73-6-2, applicable to certain of the above-referenced airplanes, is a prerequisite to the accomplishment of the actions prescribed in this AD. (b) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished. (c) In accordance with FAR Part 43, Appendix A, Item (c), the modifications required by this AD are preventative maintenance and may be performed by the holder of a pilot certificate issued under FAR Part 61 on airplanes owned or operated by him, subject to the limitations of FAR 43.3(g). The maintenance record entries required by FAR's 43.9 and 91.173 must be accomplished. (d) An equivalent means of compliance with this AD may be used if approved by the Manager, Airplane Certification Branch, Southwest Region, Department of Transportation, FAA, Fort Worth, Texas 76193-0150, Telephone (817) 624-5150. All persons affected by this directive may obtain copies of the documents referred to herein upon request to the Gulfstream Aerospace Corporation, Wiley Post Airport, P.O. Box 22500, Oklahoma City, Oklahoma 73123; or may examine these documents at the FAA, Office of the Assistant Chief Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106. This amendment revises AD 87-21-07, (Amendment 39-5741). This amendment (39-6182, AD 87-21-07 R1) becomes effective May 5, 1989.
2007-10-16: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: The Airworthiness Limitations Section of the Aircraft Maintenance Manual (AMM) applicable to the British Aerospace Jetstream 3200 has been revised. Some lives have been amended and new lives introduced. Compliance with these requirements is necessary to maintain airworthiness. We are issuing this AD to require actions to correct the unsafe condition on these products.
2022-01-03: The FAA is adopting a new airworthiness directive (AD) for certain Umlaut Engineering GmbH (previously P3 Engineering GmbH) HAFEX (Halon-free) hand-held P3HAFEX fire extinguishers (fire extinguishers). This AD was prompted by reports of a quality control issue on certain fire extinguishers, where the spindle geometries of the fire extinguishers were found to be out of tolerance. This AD requires removing affected fire extinguishers from service. The FAA is issuing this AD to address the unsafe condition on these products.
2007-10-15: The FAA is adopting a new airworthiness directive (AD) to supersede AD 2006-06-06, which applies to certain Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. AD 2006-06-06 currently requires you to incorporate information into the applicable section of the Airplane Flight Manual (AFM) and Pilot's Operating Handbook (POH) and requires you to install placards. Since we issued AD 2006-06-06, Cessna issued new S1 Known Icing Equipment AFM supplements and developed a low airspeed awareness system. Consequently, this AD requires you to incorporate the applicable AFM supplement revision and temporarily retain the requirements of AD 2006-06-06 until the above revisions are incorporated. One of the AFM requirements is the installation of a functional low airspeed awareness system to operate the airplane in known icing conditions. We are issuing this AD to assure that the pilot has enough information and the necessary equipment to prevent loss of control of the airplane while in-flight during icing conditions.
2021-26-16: The FAA is adopting a new airworthiness directive (AD) for certain type certificated Model UH-1H restricted category helicopters. This AD was prompted by multiple reports of failure of the main driveshaft. This AD requires establishing a limit to replace certain main driveshafts, and a one-time and repetitive inspections of the main driveshafts. The FAA is issuing this AD to address the unsafe condition on these products.
2007-10-09: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-400 series airplanes. This AD requires repetitive inspections for any crack in the upper deck floor beam at station 400, which include inspecting the floor beam web and chords, certain fastener holes at the intersection of the floor beam and frame on both sides of the airplane, and certain floor panel attachment fastener holes at the floor beam upper chords. This AD also requires corrective action if necessary. This AD results from several reports indicating that fatigue cracking was found in upper deck floor beams made from 7000 series aluminum alloy. We are issuing this AD to detect and correct cracking in the upper deck floor beam at station 400, which could extend and sever the floor beam. A severed floor beam could result in loss of controllability and rapid decompression of the airplane.
2021-25-06: The FAA is superseding Airworthiness Directive (AD) 2018-25- 16, which applied to certain Airbus Defense and Space S.A. Model CN- 235, CN-235-200, and CN-235-300 airplanes. AD 2018-25-16 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2018-25-16, the FAA has determined that additional new or more restrictive airworthiness limitations, including inspections for discrepancies (cracking) of certain structural elements, are necessary. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations, and repetitive inspections for discrepancies (cracking) of certain structural elements and corrective actions; 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.
2007-10-05: The FAA is adopting a new airworthiness directive (AD) for GE GE90-110B1, -113B, and -115B series turbofan engines with certain Turbine Center Frames (TCFs) installed. This AD requires removing certain TCFs, listed by part number (P/N) in this AD, from service before exceeding 14,300 flight cycles. This AD results from a report that GE inadvertently omitted some TCF P/Ns from the Airworthiness Limitations Section (ALS) of the engine manual. We are issuing this AD to prevent structural failure of the TCF with uncontained failure of low pressure turbine (LPT) rotating parts. Uncontained failure of the LPT rotating parts could result in damage to the airplane and possible loss of control of the airplane.
