2015-13-06: We are superseding Airworthiness Directive (AD) 2013-14-05 for certain The Boeing Company Model 747-400 and 747-400F series airplanes. AD 2013-14-05 required repetitive inspections of the longeron extension fittings for cracking, and related investigative and corrective actions if necessary. This new AD would continue to require the actions specified in AD 2013-14-05, and would add new repetitive high frequency eddy current (HFEC) inspections of any modified, repaired, or replaced longeron extension fitting for cracking, and applicable related investigative and corrective actions if necessary. This AD was prompted by reports of cracking in the outboard flange of the longeron extension fittings, and our determination that more work is necessary on airplanes on which a permanent repair, longeron extension fitting replacement, or modification was accomplished. We are issuing this AD to detect and correct cracks in the longeron extension fittings, which can become large and adversely affect the structural integrity of the airplane.
2022-19-15: The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines, LLC (IAE LLC) PW1122G-JM, PW1124G1- JM, PW1124G-JM, PW1127G1-JM, PW1127GA-JM, PW1127G-JM, PW1129G-JM, PW1130G-JM, PW1133GA-JM, and PW1133G-JM model turbofan engines. This AD was prompted by an analysis of an event involving an International Aero Engines AG (IAE AG) V2533-A5 model turbofan engine, which experienced an uncontained failure of a high-pressure turbine (HPT) 1st-stage disk that resulted in high-energy debris penetrating the engine cowling. This AD requires performing an ultrasonic inspection (USI) of the HPT 1st-stage disk and HPT 2nd-stage disk and, depending on the results of the inspections, replacement of the HPT 1st-stage disk or HPT 2nd-stage disk. The FAA is issuing this AD to address the unsafe condition on these products.
2010-19-02: 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: During a recent production fuel system test, it was found that all three flapper valves located in each collector tank did not conform to the design requirements, due to the fact that a valve spring was installed on the flapper hinge pin. This valve spring should have been removed prior to installation of the valves. * * * * * With the valve spring installed, the flapper valve is held closed by the valve spring, preventing gravity feed. In the event of scavenge system failure, the collector tank fuel level can no longer be maintained, potentially leading to an in-flight engine shutdown. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
2000-11-25: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320-232 and -233 series airplanes, that requires replacement of the fuel metering units (FMU) of each engine with modified FMU's. 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 an inadvertent increase in thrust, which could result in reduced controllability of the airplane during final approach.
56-09-01: 56-09-01 HILLER: Applies to All UH-12 Series Helicopters. Compliance required as indicated. Failures of tail rotor tension-torsion (T-T) bars, P/N 55003, have occurred in the threaded portion of the bars adjacent to the Rosan inserts in the yoke. These failures caused loss of the tail rotor and directional control of the helicopter. The failures were caused by excessive stresses in the T-T bars which resulted from adverse accumulation of machining and assembly tolerances and from unfavorable orientation of the T-T bar within the blade assembly. Excessive wear of the oilite bushings in the tail rotor blade root fitting may also cause high stresses in the bars. 1. To prevent recurrences of these T-T bar failures the following actions are required before the 100-hour replacement time of the T-T bars specified in telegraphic AD dated 11-1-55 has been accumulated. (a) Disassemble the tail rotor blade sufficiently to determine the diametral clearance between the outside diameter of the tail rotor yoke and the inside diameter of the oilite bushings within the blade root fitting. If the differences in diameters exceed 0.005 inch, replace the bushings as necessary to obtain diametral clearances of 0.001 inch to 0.003 inch. (b) Determine the run-out of the T-T bar at the Rosan insert in the yoke and at the end block in the blade root fitting. Methods of measuring the run-out are covered in Hiller Service Bulletin No. 53. (c) Determine the orientation of the axes of the T-T bar as originally assembled. The major axis of the T-T bar elliptical section must be 90 degrees plus or minus 15 degrees to the blade chord. (d) If the major axis of the T-T bar elliptical section is found to be within 15 degrees of the perpendicular to the blade chord upon initial inspection and if the run-out is not greater than tolerances specified in Hiller Service Bulletin No. 53, the T-T bar may be continued in further use as provided in item 3. If one or both of the above conditions are not satisfied at the initial inspection, the T-T bar shall be replaced with a new bar at the time of this inspection. 2. Repeat the inspection for diametral clearance specified in item 1(a) at not to exceed every 150 hours of operation. 3. Replace the T-T bars at not to exceed every 600 hours of operation regardless of the conditions found in the 150-hour inspection periods. 4. Replaced T-T bars shall be mutilated to preclude further use in this application. This supersedes AD 53-02-02 and telegraphic AD dated November 1, 1955.
2015-15-11: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This AD was prompted by reports of skin cracks and subsequent findings of hidden corrosion found on the mating surfaces between certain skin and stringers at circumferential skin splices. This AD requires general visual inspections of the fuselage skin at certain lower circumferential splices for the presence of existing external doublers, repetitive inspections of the fuselage skin, and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct hidden corrosion due to compromised fillet seals, which can result in skin cracking and consequent loss of capability to support limit loads.

Compliance: Required as indicated, unless accomplished previously. To prevent reduced directional control due to loss of the nose landing gear wheel during taxiing or landing, accomplish the following: (a) Within 4 months after the effective date of this AD, modify the nose landing gear wheels in accordance with Airbus Industrie Service Bulletin No. A320-32-1061, Revision 3, dated October 19, 1992. (b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113. NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113. (c) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished. (d) The modification shall be done in accordance with Airbus Industrie Service Bulletin No. A320-32-1061, Revision 3, dated October 19, 1992, which contains the following list of effective pages: Page Number Revision Level Shown on Page Date Shown on Page 1-4 3 October 19, 1992 5-7 1 June 10, 1991 This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. Copies may be obtained from Airbus Industrie, 1 Rond Point MauriceBellonte, 31707 Blagnac Cedex, France. Copies may be inspected at the FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC. (e) This amendment becomes effective on November 24, 1993.
2012-11-09 R1: We are revising Airworthiness Directive (AD) 2012-11-09 for certain transport category airplanes. AD 2012-11-09 required either activating all chemical oxygen generators in the lavatories until the generator oxygen supply is expended, or removing the oxygen generator(s); and, for each chemical oxygen generator, after the generator is expended (or removed), removing or restowing the oxygen masks and closing the mask dispenser door. AD 2012-11-09 also required installing a supplemental oxygen system in affected lavatories, which terminated the requirements of AD 2012-11-09. This AD clarifies a certain restriction by providing a broader method of compliance. This AD was prompted by the discovery that the requirement to change the instructions for continued airworthiness under certain conditions may impose an unnecessary burden on operators. We are issuing this AD to eliminate a hazard that could jeopardize flight safety, and to ensure that all lavatories have a supplemental oxygen supply.
2000-11-20: This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model DHC-8-100 and -300 series airplanes, that requires revising the Aircraft Log Book to correct the airplane Production Modification List; performing an inspection to determine which bonded skin panels on the airplane require bonding integrity inspections (BII); and revising the Airworthiness Limitations List of the Approved Maintenance Plan to include the BII requirements. This amendment also requires, for certain airplanes, repetitive ultrasonic bond inspections to detect disbonding of airplane skin panels, and repair, 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 damage to bonded skin panels to go undetected, which could result in failure of the bonded skin panels, and consequent loss of controllability of the airplane.
2000-11-28: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 and 767-200 and -300 series airplanes, that requires repetitive inspections to detect damage and wear of the auxiliary track assembly of the thrust reverser, and corrective actions, if necessary. This amendment also requires eventual repair of the auxiliary track assembly, or replacement of the slider and liner or the entire assembly, with new, improved parts, which, when accomplished, would terminate the repetitive inspections. This amendment is prompted by reports of damage and wear to the auxiliary track assembly. The actions specified by this AD are intended to prevent a slider disengaging from the auxiliary track assembly, which could lead to separation of a portion of the thrust reverser from the airplane during flight, possible impact of separated portions on airplane structure, and consequent possible rapid decompression of the airplane, reduced controllability of the airplane, or reduced structural integrity of the fuselage.
2015-15-08: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes. This AD was prompted by testing of the spoiler electronic control unit (SECU) software for an upgrade, which revealed a timing error between the command and monitor channels. This AD requires revising the maintenance or inspection program to incorporate repetitive operational tests of the aileron disconnect system, and corrective action if necessary. This AD also requires modification and reidentification of the SECU, which would terminate the repetitive operational tests. We are issuing this AD to prevent a timing error in the SECU software, which, in combination with failure of the roll disconnect switch, could result in complete loss of spoiler functionality and consequent reduced controllability of the airplane.
2000-11-19: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767-200 and -300 series airplanes, that requires repetitive inspections to detect wear or damage of the door latches and disconnect housings in the off-wing escape slide compartments, and replacement of any discrepant component with a new component. This amendment is prompted by reports of worn and damaged door latches and disconnect housings in the off-wing escape slide compartments. The actions specified by this AD are intended to ensure deployment of an escape slide during an emergency evacuation. Non-deployment of an escape slide during an emergency could slow down the evacuation of the airplane and result in injury to passengers or flightcrew. The actions specified by this AD are also intended to detect damaged disconnect housings in the off-wing escape slide compartments, which could result in unexpected deployment of an escape slide during maintenance, and consequent injury to maintenance personnel.
2000-12-05: This amendment supersedes an existing airworthiness directive (AD), applicable to International Aero Engines AG (IAE) V2500-A1/-A5/-D5 series turbofan engines, that requires revisions to the Airworthiness Limitations Section (ALS) and Maintenance Scheduling Section (MSS) of the Instructions for Continued Airworthiness (ICA), located in the Time Limits Manual (Chapter 05-10-00) of the Engine Manuals, to include required enhanced inspection of selected critical life-limited parts at each piece-part exposure. This action would add additional critical life-limited parts for enhanced inspection. This action is prompted by additional focused inspection procedures that have been developed by the manufacturer. The actions specified by this AD are intended to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.
89-03-03: 89-03-03 PARTENAVIA COSTRUZIONI AERONAUTICHE, SPA: Amendment 39-6117. Applicability: Models P 68, P 68B, P 68C, P 68TC, P 68 "Observer", and P 68TC "Observer" (all serial numbers) airplanes certificated in any category. Compliance: Required within the next 25 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished after the last engine removal. To prevent loss of structural integrity of the engine mounts, accomplish the following as referenced in Partenavia Service Bulletin (SB) No. 76 dated December 23, 1988: (a) Inspect the engine mounting system as follows for both engines: (1) Prepare the airplane as necessary as described for "ENGINE REMOVAL" in the Partenavia Maintenance Manual and support the engine with a hoist. (2) Remove the mount bolts (P/N MS 20006-12) from the airframe one-by-one starting with the lower bolts. (3) With a 10x magnifier, visually inspect the bolts for cracks, circumferential scoring, corrosion, or absence of protective coating on the shank of the bolt. Prior to further flight discard all damaged bolts, and replace with serviceable bolts. (4) Insure that washers (P/N MS 20002-C6) are properly installed on all the engine mount attachment bolts with the chamfer in the hole mating with the head of the bolt. (5) Reinstall undamaged bolts or replacement bolts and washers. Starting with the upper bolts, torque each to 335 to 375 inch-pounds. (6) Prepare the airplane for flight as described in "INSTALLATION OF ENGINE" in the Partenavia Maintenance Manual. (b) Repeat the requirements of paragraph (a) of this AD at any subsequent engine removal. (c) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished. (d) An equivalent means of compliance with this AD may be used if approved by the Manager, Aircraft Certification Division, AEU-100, Europe, Africa, and Middle East Office, FAA, c/o American Embassy, B-1000 Brussels, Belgium.

This amendment (39-6117, AD 89-03-03) becomes effective on February 16, 1989.
2015-13-07: We are superseding Airworthiness Directive (AD) 98-13-23 for certain Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 98-13-23 required inspections to detect corrosion and cracking of the lower horizontal stabilizer cutout longeron, the corner fitting, the skin strap, and the outer skin; and repair, if necessary. This new AD reduces the compliance times and repetitive intervals, and changes the inspection procedures. This AD was prompted by the determination that the risk of cracking is higher than initially determined. We are issuing this AD to prevent cracking of the lower horizontal stabilizer cutout longeron, the corner fitting, the skin strap, and the outer skin, which could result in reduced structural integrity of the horizontal-stabilizer cutout longeron.
63-17-03: 63-17-03 LOCKHEED: Amdt. 599 Part 507 Federal Register August 10, 1963.

(f) Upon request of the operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Western Region, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for such operator. (Lockheed Service Information Letter 88/SIL-62 and Lockheed Service Bulletin 88/SB- 579 cover this same subject.) This directive effective September 12, 1963. Revised November 21, 1963.
2010-19-03: We are adopting a new airworthiness directive (AD) for certain Model 737-700 (IGW) series airplanes. This AD requires deactivation or modification of PATS Aircraft, LLC, auxiliary fuel tanks. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
2000-11-16: This amendment supersedes Airworthiness Directive (AD) 97-17-03, which currently requires you to accomplish the following on Ayres Corporation (Ayres) S2R Series and Model 600 S2D airplanes: inspect the 1/4-inch and 5/16-inch bolt hole areas on the lower spar caps for fatigue cracking; replace any lower spar cap where fatigue cracking is found; and report any fatigue cracking. This AD retains the inspection and replacement (if necessary) requirements of the lower spar caps that are currently required in AD 97-17-03. This AD also makes these inspections repetitive, adds additional airplanes to the Applicability of the AD, changes the initial compliance time for all airplanes, and arranges the affected airplanes into groups (six) based on usage and configurations. The existing AD was the result of an accident of an Ayres S2R series airplane where the wing separated from the airplane in flight. The actions specified by this AD are intended to detect and correct fatigue cracking of the lower spar caps, which could result in the wing separating from the airplane with consequent loss of control of the airplane
81-26-51 R3: 81-26-51 R3 LOCKHEED-CALIFORNIA COMPANY: Amendment 39-4328 as amended by Amendment 39-4555 is further amended by Amendment 39-4722. Applies to Lockheed Model L-1011-385 series airplanes, serial numbers 1052 and subsequent, certificated in all categories. Compliance is required as indicated, unless previously accomplished. To detect cracks in the Fuselage Station (FS) 1363 bulkhead lower caps, fuselage skin, adjacent web, and web horizontal stiffeners; and to prevent failure and possible sudden decompression of the airplane, accomplish the following: A. Compliance Schedule: 1. Compliance is required within 300 landings after the effective date of this AD for the inspection specified in paragraph C., below, on all aircraft having accumulated 10,000 or more landings, as of the effective date of this AD.

2015-15-03: We are adopting a new airworthiness directive (AD) for all General Electric Company (GE) GEnx turbofan engine models. This AD was prompted by reports of GEnx-1B and GEnx-2B engines experiencing power loss in ice crystal icing (ICI) conditions. This AD precludes the use of full authority digital engine control (FADEC) software, version B175 or earlier, in GEnx-1B engines, and the use of FADEC software, version C065 or earlier, in GEnx-2B engines. We are issuing this AD to prevent engine failure, loss of thrust control, and damage to the airplane.
2015-14-03: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes. This AD was prompted by fuel system reviews conducted by the manufacturer. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new limitations for fuel tank systems. We are issuing this AD to prevent potential ignition sources within the fuel system, which could result in a fuel tank explosion.
2000-11-17: This amendment supersedes an existing airworthiness directive (AD) that applies to Eurocopter France Model SA-365N1, AS-365N2, and SA-366G1 helicopters and that currently requires initial and repetitive inspections of the tail rotor blade Kevlar tie-bar (Kevlar tie-bar) for cracks or delaminations. This amendment requires the same actions required by the existing AD and corrects an incorrectly stated part number (P/N) in the existing AD. This amendment is prompted by a report of delamination of a Kevlar tie- bar. The actions specified by this AD are intended to detect cracks that could lead to delamination of the Kevlar tie-bar, loss of tail rotor control, and subsequent loss of control of the helicopter.
