2007-19-14: We are adopting a new airworthiness directive (AD) for the products listed above that would supersede existing ADs. 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: Findings of corrosion, wear and cracks in the upper wing strut fittings on some PC-6 aircraft have been reported in the past. It is possible that the spherical bearing of the wing strut fittings installed in the underwing can be loose in the fitting or cannot rotate because of corrosion. In this condition, the joint cannot function as designed and fatigue cracks may then develop. Undetected cracks, wear and/or corrosion in this area could lead to failure on the upper attachment fitting. This could result in the failure of the wing structure with subsequent loss of control of the aircraft. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
2001-08-06: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300 B4-620, A310-203, A310-221, and A310-222 series airplanes, that requires repetitive inspections of fuselage frame 07 in the upper frame section assemblies of the lateral cockpit windows, and corrective action, if necessary. Accomplishment of certain corrective actions extends the repetitive inspection interval. The actions specified by this AD are intended to detect and correct fatigue cracking in that area, which could result in reduced structural integrity of the airplane.
2017-17-15: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports of failures of the landing gear alternate-extension system. This AD requires replacement of certain nose landing gear and main landing gear electro-mechanical actuators. We are issuing this AD to address the unsafe condition on these products.
2001-08-08: This amendment adopts a new airworthiness directive (AD) that applies to all Raytheon Aircraft Company (Raytheon) Beech Models 35-C33A, E33A, E33C, F33A, F33C, S35, V35, V35A, V35B, 36, and A36 airplanes that incorporate a certain Teledyne Continental engine configuration. This AD requires you to repetitively replace the existing Aeroquip V-band exhaust clamp. The actions specified by this AD are intended to prevent the tailpipe from detaching from the turbocharger due to failure of the V-band exhaust clamp. Clamp failure could result in the release of high temperature gases inside the engine compartment with the potential for a consequent fire in the engine compartment.
2019-19-02: The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 and 747-400F series airplanes. This AD was prompted by an evaluation that determined fatigue cracks could develop in the underwing longerons. This AD requires repetitive inspections of the underwing longerons and certain fuselage skins for any crack, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
2017-17-14: We are adopting a new airworthiness directive (AD) for certain Saab AB, Saab Aeronautics Model 340A (SAAB/SF340A) airplanes. This AD was prompted by the discovery of circuit breakers of unsuitable strength that fail to protect the system from an overcurrent. This AD requires replacing certain circuit breakers. We are issuing this AD to address the unsafe condition on these products.
2001-08-04: This amendment supersedes an existing airworthiness directive (AD) for Bell Helicopter Textron Inc. (BHTI) Model 205A-1, 205B, 212, 412, and 412CF helicopters. That AD currently requires inspecting the locking washer on each main rotor actuator (actuator) for twisting or damage to the tab and replacing any locking washer that has a twisted or damaged tab. Replacing certain locking washers, regardless of condition, is also required within a specified time period. Installing a certain airworthy locking device on each actuator constitutes terminating action for the requirements of that AD. This amendment requires the same actions as the existing AD but adds the BHTI Model 412EP helicopters to the applicability. This amendment is prompted by the discovery that the BHTI Model 412EP helicopter was inadvertently omitted from the existing AD. The actions specified by this AD are intended to prevent an actuator piston from unthreading from its rod end, loss of control of the mainrotor, and subsequent loss of control of the helicopter.
2018-10-03: We are adopting a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL 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 abrasion damage to the wing leading edge that could result in a fuel leak. We are issuing this AD to require actions to address the unsafe condition on these products.
94-03-09: This amendment adopts a new airworthiness directive (AD), applicable to all Lockheed Model L-1011-385 series airplanes, that requires inspection, modification, and replacement, if necessary, of the flap vane lugs. This amendment is prompted by reports of failure of flap vane lugs due to stress corrosion. The actions specified by this AD are intended to prevent failure of the flap vane lugs, which could lead to separation of flap vane from the airplane and cause injury to people or damage to property on the ground.
2007-19-19: The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 747 series airplanes. The existing AD currently requires repetitive inspections and torque checks of the hanger fittings and strut forward bulkhead of the forward engine mount and adjacent support structure, and corrective actions if necessary. The existing AD also currently requires a terminating action for the repetitive inspections and checks. This new AD requires, among other actions, new repetitive inspections in the existing area and new areas. This new AD also provides for an optional inspection and no longer allows the existing fastener replacement to terminate repetitive inspections. This AD results from new reports of under-torqued or loose fasteners, a cracked bulkhead chord, and a fractured back-up angle after operators accomplished the terminating action required by the existing AD. We are issuing this AD to detect and correct loose fasteners and/or damaged or cracked hanger fittings, back-up angles, and bulkhead of the forward engine mount, which could lead to failure of the hanger fitting and bulkhead and consequent separation of the engine from the airplane. \n\nDATES: This AD becomes effective October 9, 2007. \n\n\tThe Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of October 9, 2007. \n\tOn December 6, 2000 (65 FR 69862, November 21, 2000), the Director of the Federal Register approved the incorporation by reference of Boeing Alert Service Bulletin 747-54A2203, dated August 31, 2000. \n\n\tWe must receive any comments on this AD by November 20, 2007.
2001-08-01: This amendment adopts a new airworthiness directive (AD) that applies to certain JanAero Devices (JanAero) fuel regulator and shutoff valves used with JanAero combustion heaters that are installed on airplanes. This AD requires you to visually inspect and pressure test for leaks, and, if leaks are found, replace the fuel regulator and shutoff valve used with JanAero combustion heaters. This AD is the result of numerous reports of fuel regulator and shutoff valves leaking fuel. The actions specified by this AD are intended to prevent fuel leakage in airplanes with these combustion heaters with a consequent hazardous fire.
2019-20-13: The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200, A330-200 Freighter, and A330-300 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. The FAA is issuing this AD to address the unsafe condition on these products.

2007-19-16: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747 series airplanes. That AD requires a one-time inspection for discrepancies of the potable water and drain lines in the cargo compartments, and corrective action if necessary. This new AD requires that the inspection be repetitively performed using new service information, until terminating action is done. This AD also removes certain airplanes from the applicability. This AD results from a report of a fire in the aft cargo compartment started by a potable water line heater tape. We are issuing this AD to prevent overheating of the heater tape on potable water fill and drain lines, which could ignite accumulated debris or contaminants on or near the potable water fill and drain lines, resulting in a fire in the airplane.
2001-07-09: This amendment supersedes an existing emergency airworthiness directive (AD) that applies to MD Helicopters Inc. (MDHI) Model MD-900 helicopters. That emergency AD requires, within 6 hours time-in-service (TIS), or before further flight after January 31, 2000, whichever occurs first, inspecting the main rotor upper hub assembly drive plate attachment flange (flange) and determining the torque of each flange nut (nut). If a crack is found, the hub assembly must be replaced before further flight. The emergency AD also requires, within 25 hours TIS or before further flight after January 31, 2000, whichever occurs first, inspecting the hub assembly and verifying that the torque on the nuts is correct. Replacing a cracked hub assembly with an airworthy hub assembly is required before further flight. This amendment requires the same actions as the existing emergency AD but removes the January compliance dates and corrects errors in the existing emergency AD. This amendment isprompted by the discovery that there are several errors in the emergency AD. The actions specified by this AD are intended to prevent failure of the hub assembly, loss of drive to the main rotor, and subsequent loss of control of the helicopter.

2007-19-12: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from Mandatory Continuing Airworthiness Information (MCAI) provided by the aviation authority of France to identify and correct an unsafe condition on SICMA Aero Seat 50XXX Passenger Seats. The MCAI states the following: \n\n\tA release of smoke was experienced in the passenger compartment during flight after an overheating of a reading lights power box of a PN 5039201-4T SICMA seat. An analysis put into evidence that this overheating was caused by a short-circuit produced by the rupture of an electrical power supply component (PN 78147-B). It has been noticed that this power supply is not in compliance with DO 160 environmental standard. \n\n\tThe short-circuiting could result in arcing and consequent smoke or fire. We are proposing this AD to prevent a short-circuit in the power box, which could result in smoke or fire in the airplane cabin.
2004-20-05: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes. This AD requires revising the airplane flight manual to provide procedures for the flightcrew to follow in the event of the loss of all liquid crystal display (LCD) units on airplanes equipped with a certain EIS2 standard of electronic instrument system. This AD is prompted by reports of the brief but total loss of all LCD units during cruise on airplanes equipped with that standard of electronic instrument system. We are issuing this AD to provide procedures to the flightcrew to restore operation of these LCD units and prevent prolonged loss of critical flight information to the flightcrew and the consequent reduced ability of the flightcrew to control the airplane during adverse flight conditions.

Remove from further service fuel pump assemblies having unsatisfactory running torque inspection results unless modified as specified in Section 2, "Accomplishment Instructions," in SB TPE331-73-0121, Revision 2, or equivalent approved by the Manager, Western Aircraft Certification Office. Fuel control/pump assemblies having satisfactory inspection results may be continued in service until fuel pump disassembly per Paragraph (b) below. (b) Upon disassembly of fuel pump for any reason, reassemble to an approved parts configuration as specified in Section 2, "Accomplishment Instructions," in SB TPE331-73-0121, Revision 2, or equivalent approved by the Manager, Western Aircraft Certification Office. (c) Special flight permits may be issued in accordance with Federal Aviation Regulation FAR 21.197 and FAR 21.199 to ferry aircraft to a maintenance base in order to comply with the requirements of this AD. (d) Alternative means of compliance providing an equivalent level of safety may be used when approved by the Manager, Western Aircraft Certification Office, FAA, Northwest Mountain Region. (e) Upon request of the operator, an FAA Maintenance Inspector, subject to prior approval of the Manager, Western Aircraft Certification Office, FAA, Northwest Mountain Region, may adjust the compliance schedule specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the adjustment for that operator. (f) The Manager, Western Aircraft Certification Office has found GTEC SB TPE331-73-0121 Revision 3, dated November 5, 1984, to be equivalent to GTEC SB TPE331-73-0121 Revision 2 dated April 18, 1984. This revision only adds the fuel pump assembly P/N. There are no changes in inspections or accomplishment instructions. 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 this document from the manufacturer may obtain copies upon request to Garrett Turbine Engine Company, 111 South 34th St., P.O. Box 5217, Phoenix, Arizona 85010; telephone (602) 231-1000. This document also may be examined at FAA Rules Docket 83-ANE-29, New England Region, Office of the Regional Counsel, 12 New England Executive Park, Burlington, Massachusetts 01803. This amendment supersedes Amendment 39-4840 (49 FR 13487), AD 84-07-08. Amendment 39-4867 became effective May 30, 1984. This Amendment 39-4964 becomes effective on December 26, 1984.
2007-19-15: The FAA is superseding an existing airworthiness directive (AD), which applies to all McDonnell Douglas Model MD-10-10F and MD-10- 30F airplanes, Model MD-11 and MD-11F airplanes, and Model 717-200 airplanes. That AD currently requires a revision to the Limitations section of the airplane flight manual (AFM) to prohibit use of the flight management system (FMS) profile (PROF) mode for descent and/or approach operations unless certain conditions are met. This new AD requires, for certain Model 717-200 airplanes, upgrading the versatile integrated avionics (VIA) digital computer with new system software, which would end the need for the AFM revision. This AD results from a report of two violations of the selected flight control panel (FCP) altitude during FMS PROF descents. We are issuing this AD to prevent, under certain conditions during the FMS PROF descent, the uncommanded descent of an airplane below the selected level-off altitude, which could result in an unacceptable reduction in the separation between the airplane and nearby air traffic or terrain.
2001-07-10: This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-9-81, -82, -83, and -87 series airplanes, Model MD-88 airplanes, and Model MD-90-30 series airplanes. This action requires a revision to the applicable Airplane Flight Manual (AFM) to provide the flightcrew with the appropriate landing distance and flap positions, if applicable, for wet or icy runways. This AD also provides for an optional terminating action for the applicable AFM revision. This action is necessary to prevent the flightcrew from performing a scheduled landing on a runway of potentially insufficient length due to failure of the weight-on-wheels spoiler lockout mechanism system and possible inactivation of the autospoiler actuator, which could result in the airplane overrunning the end of the runway during landing on a wet or icy runway. This action is intended to address the identified unsafe condition.
