Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, and A321 series airplanes; and Model A320-211, -212, -214, -231, -232, and -233 airplanes. This proposed AD was prompted by reports of wear of the trimmable horizontal stabilizer actuator (THSA). This proposed AD would require repetitive inspections of the THSA for damage, and replacement if necessary; and replacement of the THSA after reaching a certain life limit. We are proposing this AD to detect and correct wear on the THSA, which would reduce the remaining life of the THSA, possibly resulting in premature failure and consequent reduced control of the airplane.
Airworthiness Directives; Kidde Graviner
We propose to adopt a new airworthiness directive (AD) for certain Kidde Graviner hand-operated fire extinguishers as installed on, but not limited to, various transport and small airplanes. This proposed AD was prompted by a report that a fire extinguisher failed to operate when the activation lever was pressed. This proposed AD would require modifying the affected fire extinguishers. We are proposing this AD to prevent fire extinguishers from failing to operate in the event of a fire, which could jeopardize occupants' safety and continuation of safe flight and landing.
Airworthiness Directives; Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the upper and lower rainbow fittings on the outer wing are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections of the upper and lower rainbow fittings on the outer wing to detect cracks propagating from fasteners attaching the fittings to skin panels, and related investigative and corrective actions if necessary; and replacement of the upper and lower rainbow fittings on the outer wing. We are proposing this AD to prevent fatigue cracking of the upper and lower rainbow fittings on the outer wing and skin-panel-to-fitting fastener holes, which could result in reduced structural integrity of the airplane and possible separation of the wing from the airplane.

Public Notice for Waiver of Non-Aeronautical Land-Use Assurance Related to the Proposed Release and Exchange of Airport Property at Acadiana Regional Airport, New Iberia, Louisiana
The Federal Aviation Administration (FAA) is considering a proposal to authorize the release and exchange of approximately 7.231 acres of the airport property at the Acadiana Regional Airport, New Iberia LA, owned by the New Iberia Parish. The Parish is proposing a land swap to exchange this 7.231 acre parcel for another parcel of approximately 10.548 acres. The acreage being released is not needed for aeronautical use as currently identified on the Airport Layout Plan. The new proposed parcel will be used for the Acadiana Regional Airport, New Iberia LA, Access Road project from Louisiana Highway 675 (Jefferson Island Road) to Louisiana Highway 3212 (Northwest Bypass). The acreage being released comprising this parcel was originally acquired in 1970 when the Parish governing body petitioned the U.S. government for release of 2,100 acres of previously the Naval Air Station New Iberia property for civil aviation use through the General Services Administration excess land disposal process. In exchange for the 7.231 acres the airport will receive a new parcel of land described above for the Acadiana Regional Airport, New Iberia LA, Access Road project. The 7.231 acre parcel (Tract 14) is Zoned ``I-1: Industrial'' and has access to LA Highway 3212 (Prairie Road) and is being proposed to be swapped for approximately 10.548 acres (Tract 13) Zoned ``A-1: Agricultural''. The appraised fair market value of the proposed 7.231 acres parcel is $64,000, the fair market value of the proposed acquired parcel is $58,000. The difference of $6,000 in fair market value between Tract 14 and Tract 13 will be compensated by the Iberia Parish Council to the Iberia Airport Authority to accommodate FAA auditing standards and requirements to prevent the potential for ``diversion of funds (assets)''. A Phase I, Environmental Site Assessment was conducted and published on April 14, 2014 resulting in the assessment that did not reveal any evidence of Recognized Environmental Conditions (RECs) in connection with the new acquired property. This action and the affected properties have been evaluated by the Department of the Army, New Orleans District, Corps of Engineers, the State Office of Historic Preservation, Department of Culture, Recreation and Tourism, and the Louisiana Ecological Services Office with a determination of an activity that would not negatively affect any wetland subject to Corps' jurisdiction, historical properties or threatened or endangered species respectively. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds (or compensation) from the disposal of the airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. In accordance with section 47107(c)(2)(B) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose and concurring with the proposed land swap.

Airworthiness Directives; Airbus Helicopters, Inc. (Previously Eurocopter France) Helicopters
We are superseding airworthiness directive (AD) 2012-02-13 for certain Airbus Helicopters, Inc. (Airbus Helicopters) Model EC130B4 helicopters. AD 2012-02-13 required inspecting certain areas of the tailboom/Fenestron junction frame (junction frame) for a crack. This AD retains the requirements of AD 2012-02-13, expands the inspection area of the junction frame, and reduces the repetitive inspection interval. These actions are intended to detect a crack in the junction frame, which could result in detachment of the Fenestron and subsequent loss of control of the helicopter.
Airworthiness Directives; Brantly International, Inc. Helicopters
We are adopting a new airworthiness directive (AD) for Brantly International, Inc. (Brantly) Model B-2, Model B-2A, and Model B-2B helicopters with certain main rotor blades. This AD requires inspecting each main rotor (M/R) blade for a crack or delamination and removing the blade if a crack exists or if the delamination exceeds certain thresholds. This AD was prompted by multiple reports of M/R blade cracks and an incident in which a crack that originated near the M/R blade trailing edge resulted in the loss of a large section of the M/R blade. The actions of this AD are intended to prevent loss of the M/R blade and subsequent loss of control of the helicopter.
Airworthiness Directives; Pacific Aerospace Limited Airplanes
We are superseding Airworthiness Directive (AD) 2014-04-03 for all Pacific Aerospace Limited Model 750XL 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 broken control column attachment bolts failing in service. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Alexandria Aircraft LLC Airplanes
We are superseding Airworthiness Directive (AD) 75-20-06 for certain Alexandria Aircraft LLC (type certificate previously held by Bellanca Aircraft Corp., Viking Aviation, Inc., and Bellanca, Inc.) Models 14-19-3A, 17-30, 17-30A, 17-31, 17-31A, 17-31ATC, and 17-31TC airplanes. AD 75-20-06 required repetitively inspecting the aft fuselage structure near the top of the vertical side tubing, which connects the horizontal stabilizer carry-through to the upper fuselage longeron, for cracks and installing the manufacturer's service repair kit as a terminating action for the repetitive inspections to repair any cracks found. Since we issued AD 75-20-06, we have determined that installing the service kit has not prevented cracks from occurring. We have also determined that all affected airplane serial numbers should be included in the Applicability section. This AD requires continued repetitive inspections of the aft fuselage structure near the top of the vertical side tubing for cracks and making all necessary replacements of cracked parts. This AD also adds additional serial number airplanes to the Applicability section. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Pacific Aerospace Limited Airplanes
We are adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Model 750XL 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 failure of the fin forward pickup due to possible fatigue cracks. We are issuing this AD to require actions to address the unsafe condition on these products.

Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2013-11-14 for certain The Boeing Company Model 777-200 and -300 series airplanes. AD 2013-11-14 required repetitive general visual inspections of the strut forward dry bay for the presence of hydraulic fluid, and related investigative and corrective actions (including checking drain lines for blockage due to hydraulic fluid coking, and cleaning or replacing drain lines to allow drainage) if necessary. This AD adds airplanes to the applicability. This AD was prompted by reports of hydraulic fluid contamination (including contamination caused by hydraulic fluid in its liquid, vapor, and/or solid (coked) form) found in the strut forward dry bay. We are issuing this AD to detect and correct hydraulic fluid contamination of the strut forward dry bay, which could result in hydrogen embrittlement of the titanium forward engine mount bulkhead fittings, and consequent inability of the fittings to carry engine loads, resulting in engine separation. Hydrogen embrittlement also could cause a through-crack formation across the fittings through which an engine fire could breach into the strut, resulting in an uncontained strut fire.
Airworthiness Directives; Zodiac Seats France (formerly Sicma Aero Seat) Passenger Seat Assemblies
We are superseding Airworthiness Directive (AD) 2011-07-05 for certain Sicma Aero Seat 9140, 9166, 9173, 9174, 9184, 9188, 9196, 91B7, 91B8, 91C0, 91C2, 91C4, 91C5, and 9301 series passenger seat assemblies; and Sicma Aero Seat 9501311-05, 9501301-06, 9501311-15, 9501301-16, 9501441-30, 9501441-33, 9501311-55, 9501301-56, 9501441-83, 9501441-95, 9501311-97, and 9501301-98 passenger seat assemblies. AD 2011-07-05 required a general visual inspection for cracking of backrest links, replacement with new links if cracking is found, and eventual replacement of all links with new links. This new AD requires a new general visual inspection for cracking of backrest links, which includes new seat backrest links; replacement with new links if cracking is found; and eventual replacement of all links with new links. This AD was prompted by a report that new seat backrest links could be affected by cracks similar to those identified on the backrest links with the previous design. We are issuing this AD to detect and correct cracks in the backrest links, which could affect the structural integrity of seat backrests. Failure of the backrest links could result in injury to an occupant during emergency landing conditions.

The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on July 31, 2014, vol. 79, no. 147, page 44485. FAA Form 7480-1 (Notice of Landing Area Proposal) is used to collect information about any construction, alteration, or change to the status or use of an airport.
Change of Controlling Agency for Restricted Areas; California
This action updates the name of the controlling agency for restricted areas R-2502N Fort Irwin, CA; R-2505 China Lake, CA; R-2506 China Lake South, CA; R-2508 Complex, CA; R-2515 Muroc Lake, CA and R- 2524 Trona, CA to read ``FAA, Joshua Control Facility, Edwards AFB, CA.'' This is an administrative change only as there are no changes to the dimensions, time of designation or activities conducted within the affected restricted areas.
Airworthiness Directives; Kaman Aerospace Corporation (Kaman) Helicopters
We propose to adopt a new airworthiness directive (AD) for Kaman Model K-1200 helicopters with certain main rotor blades (MRB) installed. This proposed AD would require inspecting each MRB for a crack or damage. This proposed AD is prompted by a report that a crack was found on an MRB during a tear-down inspection. The proposed actions are intended to detect a crack in the MRB, which could lead to failure of the MRB and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron Canada Limited
We are revising and reopening the comment period for an earlier notice of proposed rulemaking (NPRM) for certain Bell Helicopter Textron Canada Limited (Bell) Model 206L-3 and 206L-4 helicopters. The NPRM proposes to require installing a placard and revising the limitations section of the rotorcraft flight manual (RFM). The NPRM was prompted by several incidents of third stage engine turbine wheel failures caused by excessive vibrations at certain engine speeds during steady-state operations. This action proposes to revise the NPRM by adding certain Model 206L1 helicopters to the applicability, excluding certain Model 206L3 and 206L4 helicopters from the applicability, and changing the procedures for updating the RFM. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by reports of missing clamps that are required to provide positive separation between the alternating current (AC) feeder cables and the hydraulic line of the landing gear alternate extension. This AD requires an inspection for missing clamps that are required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension, and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct chafing of the AC feeder cable. A chafed and arcing AC feeder cable could puncture the adjacent hydraulic line, which, in combination with the use of the alternate extension system, could result in an in- flight fire.
Airworthiness Directives; Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Airplanes
We are adopting a new airworthiness directive (AD) for certain Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L-1011 series airplanes. This AD was prompted by reports of cracked rib cap castellations. This AD requires repetitive inspections for castellation and skin clips cracked or damaged between stringers and cracked stringer clips of the wing box pylon back-up structure, and front spar to rear spar; repetitive inspections for cracking, damage, or failure of the pylon back-up torque box structure; repetitive inspections for cracking or damage of the wing box external areas at the drag brace aft wing fitting; repetitive inspections of the outer surface of the wing upper and lower skins for cracks or damage along the rib attachment at the fastener holes and between the two rows of attachment; and corrective actions if necessary. We are issuing this AD to detect and correct cracked or damaged rib cap castellations, which could degrade the structural capabilities of the airplane.
Airworthiness Directives; the Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2010-03-05 for all the Boeing Company Model 747-200C and -200F series airplanes. AD 2010-03-05 required, for the upper chords of the upper deck floor beam of section 41, an inspection for cracking of certain fastener holes, and corrective action if necessary; and repetitive replacements of the upper chords, straps (or angles), and radius fillers of certain upper deck floor beams and, for any replacement that is done, inspections for cracking, and corrective actions if necessary. This new AD adds repetitive inspections of the upper chords of the upper deck floor beam of Section 42, repetitive replacements of the upper chords, post- replacement inspections, and corrective actions if necessary. This new AD also adds post-replacement inspections for section 41 and reduces certain compliance times. This AD was prompted by a determination that the upper deck floor beams are subject to widespread fatigue damage (WFD), the existing inspection program is not sufficient to maintain an acceptable level of safety, and the upper chords of the upper deck floor beam of section 42 are subject to the unsafe condition. We are issuing this AD to detect and correct cracking of the upper chords and straps (or angles) of the floor beams, which could lead to failure of the floor beams and consequent loss of controllability, rapid decompression, and loss of structural integrity of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This AD requires repetitive inspections for any fuel leak in the right-hand landing lights compartment, and related investigative and corrective actions if necessary. This AD also provides for an optional replacement of the connector of the fuel boost pump canister of the auxiliary power unit (APU), which terminates the repetitive inspections. This AD was prompted by a report of fuel leaks in the connector cavity of the APU fuel boost pump canister and at the electrical conduit connection of the APU fuel boost pump in the right- hand landing lights compartment. We are issuing this AD to detect and correct fuel leaks in the right-hand landing lights compartment, which, in combination with the heat generated by the taxi lights and landing lights on the ground reaching the auto-ignition temperature of the fuel, could result in ignition of any fuel or fumes present in the right-hand landing lights compartment.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 94-12-03 for certain Airbus Model A320 series airplanes. AD 94-12-03 required modification of the belly fairing structure. This new AD requires repetitive inspections for cracking of the four titanium angles between the belly fairing and the keel beam side panel, an inspection for cracking of the open holes if any cracking is found in the titanium angles, and repair or replacement if necessary; this new AD also expands the applicability of AD 94-12-03. This AD was prompted by reports of cracks at the lower riveting of the four titanium angles that connect the belly fairing to the keel beam side panels on both sides of the fuselage. We are issuing this AD to detect and correct cracking of the titanium angles that connect the belly fairing to the keel beam side panels on both sides of the fuselage, which could affect the structural integrity of the airplane.
