2000-14-09: This amendment adopts a new airworthiness directive (AD), applicable to certain Short Brothers Model SD3-60 series airplanes, that requires affixing a label containing revised engine limitations on the ditching hatch, and revising the airplane flight manual to reflect the revised engine limitations. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent the use of incorrect engine limitations, which could result in an overspeed of the propellers and potential for blade failure.
2000-14-04: This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 747 series airplanes. This action requires a one-time inspection of the fuselage skin adjacent to the drag splice fitting to detect cracking, and follow-on actions, if necessary. This action is necessary to detect and correct fatigue cracking of the fuselage skin, which could result in reduced structural integrity of the fuselage, and consequent rapid depressurization of the airplane.
89-18-08: 89-18-08 GULFSTREAM AEROSPACE CORPORATION: Amendment 39-6307. Applicability: Gulfstream Aerospace Models AA-5, AA-5A, AA-5B, and GA-7 (all serial numbers) airplanes certificated in any category. Compliance: Required within the next 25 hours time-in-service after the effective date of this AD, unless already accomplished. To preclude fuel tank/fuel system contamination caused by deterioration of fuel tank access cover sealant, accomplish the following: (a) Inspect the fuel tanks, fuel system, and the electric fuel pump filter for fuel tank sealant contamination in accordance with the instructions specified in Gulfstream Aerospace Corporation (GAC) Service Bulletin (SB) No. 176, dated July 26, 1989, or GAC S/B No. ME 22, dated July 26, 1989, as applicable. If contamination is detected, prior to further flight clean the fuel system and all fuel system components in accordance with the instructions in the above listed applicable GAC S/B. (b) Reseal the fuel tank access covers using high-octane fuel resistant sealant per the instructions in the applicable GAC S/B listed in paragraph (b) of this AD. (c) An equivalent means of compliance with this AD may be used if approved by the Manager, Atlanta Aircraft Certification Office, FAA, Small Airplane Directorate, Aircraft Certification Service, 1669 Phoenix Parkway, Suite 210C, Atlanta, Georgia 30349. All persons affected by this directive may obtain copies of the documents referred to herein upon request to Gulfstream Aerospace Corporation, Technical Operations Department, Travis Field, P.O. Box 2206, Savannah, Georgia 31402-2206; or may examine the documents at the FAA, Office of the Assistant Chief Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106. This amendment (39-6307, AD 89-18-08) becomes effective on September 21, 1989.
2015-17-22: We are adopting a new airworthiness directive (AD) for all Airbus Model A330-243, A330-243F, A330-341, A330-342, and A330-343 airplanes. This AD was prompted by reports indicating that certain hinge sleeves on the cowl doors of the thrust reverser units (TRUs) were not heat treated. This AD requires replacing the sleeves of certain hinges on the cowl doors of the TRUs with new parts. We are issuing this AD to prevent, in the event of a fan-blade-off event due to high vibration, in-flight loss of TRU heavy components, which might damage airplane structure or control surfaces and consequently reduce controllability of the airplane.
2000-14-02: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-600, -700, and -800 series airplanes. This action requires installation of placards on the P3-1 panel. This action is necessary to prevent loss of communication between the flight crew and Air Traffic Control; this situation could result in the flight crew being unaware of an unsafe scenario when the airplane is on the ground. This action is intended to address the identified unsafe condition.
96-05-05: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires replacement of the inlet filter in the spoiler servo-controls and installation of a lockwire. This amendment is prompted by reports of leakage of hydraulic fluid at the inlet filter plug of the spoiler actuator as a result of inadequate torque of the filter plug, and reports of broken lockwires. The actions specified in this AD are intended to prevent loss of hydraulic fluid to the extent that a complete failure of the associated hydraulic system could occur. Such a loss, when combined with other hydraulic system failures, could reduce the controllability of the airplane.
2000-14-07: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 727 series airplanes, that currently requires repetitive inspections to detect cracking of the rear spar web or fuel leakage of the wing center section, and repair, if necessary. That action also provides for an optional modification of the rear spar web that constitutes terminating action for the repetitive inspections. This amendment requires accomplishment of the previously optional terminating action. The actions specified by this AD are intended to prevent cracking of the rear spar web, which could permit fuel leakage into the airflow multiplier, and could result in an electrical short that could cause a fire.
2000-14-03: This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB SF340A and SAAB 340B series airplanes, that requires replacing the smoke detectors in the cargo compartment with new, improved smoke detectors. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent false smoke warnings from the cargo compartment smoke detectors, which could result in aborted takeoffs, diversions of flight routes, and emergency evacuation of flight crew and passengers.
2000-13-09: This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB 2000 series airplanes, that requires repetitive detailed visual and dye penetrant inspections of the backup struts in the left and right nacelles to detect discrepancies; and corrective actions, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the backup struts in the left and right nacelles due to fatigue cracking, which could result in loss of fail-safe redundancy in the design of the nacelle in terms of load capability.
2015-17-20: We are adopting a new airworthiness directive (AD) for certain serial number (S/N) GE Aviation Czech s.r.o. M601E-11, M601E-11A, and M601F turboprop engines with certain part number (P/N) gas generator turbine (GGT) blades, installed. This AD requires removing from service any affected engine with certain GGT blades installed. This AD was prompted by the determination that certain GGT blades are susceptible to blade failure. We are issuing this AD to prevent GGT blade failure, which could lead to engine failure and loss of the airplane.
