97-04-13: This amendment adopts a new airworthiness directive (AD) that applies to Mitsubishi Heavy Industries, Ltd., (Mitsubishi) MU-2B series airplanes. This AD requires removing the vent check valve assembly from the bulkhead between the fuel tanks. This AD results from an incident where both engines on an affected airplane failed near the end of a flight because of lack of fuel to the engines. The incident is attributed to the fuel filler caps on the top of the wings not sealing correctly. The actions specified by this AD are intended to prevent the inability of both engines to utilize the entire fuel supply because of the outboard fuel not transferring to the center tank, which could result in an uncommanded engine shutdown.

2014-19-01: We are superseding an airworthiness directive (AD) 2013-22-20 for Embraer S.A. Model EMB-505 airplanes. 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 cracks beyond acceptable limits in the carbon discs of the left hand (LH) and right hand (RH) brake assemblies. We are issuing this AD to require actions to address the unsafe condition on these products.
2005-01-19: The FAA is adopting a new airworthiness directive (AD) to supersede Airworthiness Directive 2004-10-15, which applies to certain GTX 330 and GTX 330D Mode S transponders that are installed on airplanes. AD 2004-10-15 currently requires you to install GTX 330/330D Software Upgrade Version 3.03, 3.04, or 3.05. This AD applies to certain GTX 33, GTX 33D, GTX 330, and GTX 330D Mode S transponders that are installed on airplanes and is the result of observations that the GTX 33/33D/330/330D may detect, from other airplanes, the S1 (suppression) interrogating pulse below the minimum trigger level (MTL) and, in some circumstances, not reply. The GTX 33/33D/330/330D should still reply even if it detects S1 interrogating pulses below the MTL. Consequently, this AD would require you to install a GTX 33/33D/330/ 330D Software Upgrade to at least Version 3.06. No additional action is necessary for those airplanes that have transponders Software Upgrade 3.03 installed. Software Upgrade Versions 3.03 and 3.06 correct a TAS, TCAD, and TCAS I system "whisper-shout" problem that could potentially lead to the aircraft not being visible at certain ranges. TCAS II systems are not affected. We are issuing this AD to prevent interrogating aircraft from possibly receiving inaccurate replies due to suppression from aircraft equipped with the GTX 33/33D/330/330D Mode S transponders when the pulses are below the MTL. The inaccurate replies could result in reduced vertical separation.
2014-07-04R1: The FAA is revising airworthiness directive (AD) 2014-07-04 that published in the Federal Register to correct certain errors. AD 2014-07-04 applied to certain Sikorsky Model S-92A helicopters. The range of serial numbers in the Applicability section and a reference to the service information in the Required Actions section of the regulatory text are incorrect. This document corrects those errors. In all other respects, the original document remains the same.
2009-06-16: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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: It has been found the occurrence of failed bearings of the RAT [ram air turbine] generator, which may lead to a RAT generator failure. The RAT generator was designed to provide emergency electrical power to essential systems in case of loss of all other sources of aircraft AC electrical power. * * * * * Loss of emergency electrical power could result in reduced controllability of the airplane during in-flight emergencies. We are issuing this AD to require actions to correct the unsafe condition on these products.
80-26-51: 80-26-51 BOEING: Amendment 39-4072. Applies to Boeing Model 737 series airplanes, certificated in all categories, prior to line number 726. To prevent control system jamming, accomplish the following within the next 150 hours time-in-service after the effective date unless already accomplished, or unless the affected bolt assemblies have been removed and reinstalled since manufacture. \n\n\t1.\tInspect the bolt assemblies installed at the upper and lower clevis of each elevator power control unit input rod assembly for proper installation in accordance with Boeing Alert Service Bulletin 27A1109, dated December 11, 1980, or later FAA-approved revisions. Bolt assemblies not properly installed must be reinstalled in accordance with the service bulletin.\n \n\t2.\tAlternate methods of compliance with this Airworthiness Directive may be used when they are approved by the Chief, Seattle Area Aircraft Certification Office, FAA Northwest Region. \n\n\tThis amendment becomes effective April 1, 1981, and was effective earlier to those recipients of telegraphic AD T80-26-51, dated December 13, 1980.
79-03-04: 79-03-04 LOCKHEED: Amendment 39-3404. Applies to all Model 382 series aircraft with Calco manufactured ballscrew assembly, P/N 8353, installed in the main landing gear (MLG). Compliance required as indicated. To prevent the collapse of the MLG due to a failure of the ballscrew P/N 8353-25 lower mounting flange and consequently possible loss of the aircraft, accomplish the following: Within 10 hours time in service after the effective date of this AD and at each preflight thereafter on all airplanes with suspect P/N 8353 ballscrew assemblies, lower mounting flange P/N 8353-25 (castings only, not forgings), perform the repetitive visual check of the MLG Calco P/N 8353 Ballscrew Assembly in accordance with Lockheed Alert Service Bulletin A328-32-28 (NOTE: Four (4) ballscrew assemblies per airplane). The checks required by this AD may be performed by the flight crew. If cracks are detected or suspected in the lower mounting flange of the P/N 8353 ballscrew assembly as a result of the above service bulletin inspection requirements, replace the P/N 8353-25 casting with a serviceable forging prior to further flight. In addition to the above repetitive visual checks the following inspection of the P/N 8353-25 casting is required: 1. Prior to 50 hours time in service from the effective date of this AD, perform a Rockwell hardness test to determine that the P/N 8353-25 casting is within acceptable hardness limits of RC-35 to RC-45. If these limits are exceeded the P/N 8353-25 casting must be replaced prior to further flight except that if only one casting per aircraft is determined to be outside these limits, a ferry flight to a place of repair is permissible. 2. If the Rockwell hardness test confirms that the P/N 8353-25 casting is within the prescribed above limits, the casting must be replaced with a serviceable forging within 25 landings or 150 flight hours, whichever occurs first. NOTE: The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1). All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to Lockheed-Georgia Company, Marietta, Georgia 30063. These documents may also be examined at FAA, Southern Regional Office, 3400 Whipple Street, East Point, Georgia, and at FAA Headquarters, 800 Independence Avenue, S.W., Washington, D.C. A historical file on this AD which includes the incorporated material in full is maintained by the FAA at its Headquarters in Washington, D.C. and at the Southern Regional Office. This amendment is effective February 5, 1979.
2009-06-06: This airworthiness directive (AD) supersedes two existing ADs. One AD applies to certain Airbus Model A310-200 and -300 series airplanes. That AD currently requires repetitive inspections for cracking of the flap transmission shafts, and replacement of the transmission shafts if necessary. That AD also provides an optional terminating action for the repetitive inspections. The other existing AD applies to all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes); and Model A310-200 and -300 series airplanes. That AD currently requires a one-time inspection of the trimmable horizontal stabilizer actuator (THSA), corrective actions if necessary, and follow-on repetitive tasks. This new AD also requires revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations and maintenance tasks for aging systems maintenance. ThisAD results from the manufacturer's determination that life limitations and maintenance tasks are necessary to ensure continued operational safety of the affected airplanes. We are issuing this AD to prevent reduced structural integrity of these airplanes due to the failure of system components. DATES: This AD becomes effective April 28, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of April 28, 2009. On August 29, 2006 (71 FR 42021, July 25, 2006), the Director of the Federal Register approved the incorporation by reference of Airbus Service Bulletin A300-27-6044, Revision 04, dated September 10, 2001; and Airbus Service Bulletin A310-27-2089, Revision 02, dated June 28, 2001. On June 20, 2006 (71 FR 28254, May 16, 2006), the Director of the Federal Register approved the incorporation by reference of Airbus Service Bulletin A310-27-2092, Revision 02, dated April 11, 2005; and Airbus ServiceBulletin A310-27-2095, dated March 29, 2000.
2005-01-17: The FAA adopts a new airworthiness directive (AD) to supersede AD 98-03-14, which applies to certain EXTRA Flugzeugbau GmbH (EXTRA) Model EA-300 and EA-300/S airplanes. AD 98-03-14 currently requires you to inspect the upper longeron cutout-bridge for cracks, to repair any cracks found, and to modify this area. This AD retains the actions of AD 98-03-14 and incorporates new service information. For owner/ operators of the affected airplanes that were able to do the modification required in AD 98-03-14, no further action is required. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to detect and correct cracks in the upper longeron cutout-bridge, which could cause the upper longeron cutout-bridge to fail resulting in structural damage to the fuselage. This condition could lead to loss of control of the airplane. DATES: This AD becomes effective on February 28, 2005. On March 16, 1998 (63 FR 5881, February 5, 1998), the Director of the Federal Register approved the incorporation by reference of EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: A, Date: January 12, 1994. As of February 28, 2005, the Director of the Federal Register approved the incorporation by reference of EXTRA Flugzeugbau GmbH Service Bulletin EA-300 & EA-300/S Doc: SB-300-3-93, Issue: B, Date: June 10, 1998.
