Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
We propose to adopt a new airworthiness directive (AD) for certain Turbomeca S.A. Arrius 2F turboshaft engines with a certain part number oil pump installed. This proposed AD was prompted by cases of deterioration of the gas generator front bearing due to a link loss between the pump driver and the oil pump shaft. This proposed AD would require inspection, and if necessary, replacement before further flight of the oil pump driver assembly and/or the oil pump shaft, or the oil pump itself. We are proposing this AD to prevent link loss between the pump driver and the oil pump shaft, which could lead to an engine in- flight shutdown, forced landing, and damage to the helicopter.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters
We are adopting a new airworthiness directive (AD) for Airbus Helicopters (previously Eurocopter France) Model AS365N3, EC155B, and EC155B1 helicopters with an external life raft in the footsteps with certain part-numbered junction units. This AD requires inspecting the junction units of the external life raft deployment system for corrosion, removing any corrosion, and performing certain measurements to determine whether the junction unit must be replaced. This AD is prompted by failure of a life raft deployment test and corrosion damage inside the left-hand junction unit. These actions are intended to prevent failure of an external life raft to deploy preventing evacuation of passengers during an emergency.

Airworthiness Directives; The Enstrom Helicopter Corporation
We are publishing a new airworthiness directive (AD) for Enstrom Helicopter Corporation (Enstrom) Model F-28A, 280, F-28C, F- 28C-2, F-28C-2R, 280C, F-28F, F-28F-R, 280F, 280FX, and 480 helicopters. This AD was sent previously to all known U.S. owners and operators of these helicopters and supersedes Emergency AD (EAD) 2015- 04-51, dated February 12, 2015. This AD requires inspecting certain main rotor spindles (spindles) for cracks and reporting the inspection results to the FAA. This AD is prompted by a fatal accident and reports of spindles with cracks. The actions specified in this AD are intended to detect a crack in a spindle and prevent loss of a main rotor blade and subsequent loss of control of the helicopter.

Notice of Availability of a Draft Environmental Assessment
The Federal Aviation Administration (FAA) proposes to fund, construct, and operate a new Airport Traffic Control Tower (ATCT) and Base Building at the General Wayne A. DowningPeoria International Airport (PIA), Peoria, Illinois. The FAA's preferred alternative is to construct the ATCT at a location approximately 1,000 feet east of the PIA terminal building. The purpose of the proposed project is to improve operational efficiency, meet existing and future operational and administrative expansion requirements, and accommodate state-of-the-art equipment upgrades. The need for the project is to provide a replacement ATCT, as the existing ATCT was constructed as part of the original terminal building, which is planned to be demolished. A new ATCT and Base Building at PIA would be able to meet these needs. The FAA has prepared a Draft Environmental Assessment (DEA) in conformance with the requirements of the National Environmental Policy Act of 1969 (NEPA) and FAA Order 1050.1E, Environmental Impacts: Policies and Procedures. The DEA analyzes the potential environmental impacts that may result from construction and operation of the proposed new ATCT and Base Building at the proposed site, as well as the no action alternative (i.e., not constructing and operating the new ATCT).
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2004-20- 14, for all Airbus Model A300 B4-2C, B4-103, and B4-203 airplanes; and all Model A300 B4-600, B4-600R, and F4-600R series airplanes. AD 2004- 20-14 requires repetitive inspections to detect cracking of the splice fitting at fuselage frame (FR) 47 between stringers 24 and 26 (left- and right-hand sides), and corrective actions if necessary. Since we issued AD 2004-20-14, we have determined that the inspection compliance time and repetitive inspection interval must be reduced to allow timely detection of cracks in the splice fitting at fuselage FR 47. This proposed AD would reduce the inspection compliance time and repetitive inspection intervals, and add Model A300 C4-605R Variant F airplanes to the applicability. We are proposing this AD to detect and correct cracking of the splice fitting at fuselage FR 47, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France)
We propose to supersede airworthiness directive (AD) 2002-13- 11 for Eurocopter France (now Airbus Helicopters) Model EC120B helicopters. AD 2002-13-11 currently requires installing front and side covers on the cabin floor to protect the yaw control at both the pilot and co-pilot stations. Since we issued AD 2002-13-11, we have determined that the required actions should apply only to the cabin's right-hand pilot station. This proposed AD would retain the requirements of AD 2002-13-11 but for only the pilot station. These proposed actions are intended to prevent an object from sliding between the canopy and the cabin floor, loss of yaw control, and subsequent loss of helicopter control.
Establishment of Class E Airspace; Cypress, TX
This action corrects the effective date of a final rule published in the Federal Register of April 24, 2015, establishing Class E airspace at Dry Creek Airport, Cypress, TX.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This proposed AD was prompted by reports of unreliable performance of the fuel scavenge system. This proposed AD would require changing the main fuel tank water scavenge system, center fuel tank fuel scavenge system, certain electrical panels; related investigative actions, and corrective actions if necessary; and for certain airplanes, changing to give redundant control of the center override/jettison fuel pumps and main jettison fuel pumps. We are proposing this AD to prevent fuel exhaustion and subsequent power loss of all engines due to loss of capability to scavenge fuel in the center fuel tank.
Notice of Request To Release Airport Property
The FAA proposes to rule and invites public comment on the release of land at the Sikeston Memorial Municipal Airport (SIK), Sikeston, Missouri, under the provisions of 49 U.S.C. 47107(h)(2).
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the lap splices of the aft pressure bulkhead webs are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections for any crack in the aft webs of the radial lap splices of the aft pressure bulkhead, and, if necessary, corrective actions. We are proposing this AD to detect and correct fatigue cracking in the aft webs of the radial lap splices of the aft pressure bulkhead, which could result in reduced structural integrity of the airplane and decompression of the cabin.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
We propose to adopt a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes, and Model ATR72-102, -202, -212, and -212A airplanes. This proposed AD was prompted by a report of chafed wires between electrical harnesses. This proposed AD would require inspections for wiring discrepancies, and corrective actions if necessary. We are proposing this AD to detect and correct damaged wiring and incorrect installation of the wiring harness and adjacent air ducts, which could lead to wire harness chafing and arcing, possibly resulting in an on-board fire.
Proposed Amendment of Class E Airspace for the Following Iowa Towns: Audubon, IA; Corning, IA; Cresco, IA; Eagle Grove, IA; Guthrie Center, IA; Hampton, IA; Harlan, IA; Iowa Falls, IA; Knoxville, IA; Oelwein, IA; and Red Oak, IA
This action proposes to amend Class E airspace at Audubon County Airport, Audubon, IA; Corning Municipal Airport, Corning, IA; Ellen Church Field Airport, Cresco, IA; Eagle Grove Municipal Airport, Eagle Grove, IA; Guthrie County Regional Airport, Guthrie Center, IA; Hampton Municipal Airport, Hampton, IA; Harlan Municipal Airport, Harlan, IA; Iowa Falls Municipal Airport, Iowa Falls, IA; Knoxville Municipal Airport, Knoxville, IA; Oelwein Municipal Airport, Oelwein, IA; and Red Oak Municipal Airport, Red Oak, IA. Decommissioning of the non-directional radio beacons (NDB) and/or cancellation of NDB approaches due to advances in Global Positioning System (GPS) capabilities has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the above airports.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2004-07-11 for all The Boeing Company Model 767-400ER series airplanes. AD 2004-07-11 requires repetitive high frequency eddy current (HFEC) inspections of the aft lower lugs of the deflection control track of the outboard flap for cracks, and replacement of any cracked deflection control track with a new track assembly. This AD retains those requirements, provides optional terminating action for the repetitive inspections, and adds airplane models to the applicability. This AD was prompted by our determination that additional airplane models require repetitive HFEC inspections of the aft lower lugs of the deflection control track of the outboard flap for cracks, and replacement of any cracked deflection control track with a new track assembly. We are issuing this AD to detect and correct fatigue cracking in the aft lower lug run-out region of the deflection control track, which could result in the loss of the secondary load path for the outboard flap, resulting in the loss of the outboard flap and consequent reduced controllability of the airplane in the event that the primary load path also fails.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-601, B4-603, and B4-605R airplanes; Model A300 F4- 605R airplanes; Model A300 C4-605R Variant F airplanes; and Model A310- 204 and -304 airplanes; powered by General Electric (GE) Model CF6-80C2 series engines. This AD was prompted by reports of two single-engine flameout events during inclement weather. This AD requires installing a shunt of the rotary selector (introducing an auto-relight function); and, for certain airplanes, a wiring modification to a certain circuit breaker panel. We are issuing this AD to prevent a long engine restart sequence after a non-selection of continuous relight by the crew and a flameout event of both engines, which could result in reduced controllability of the airplane, especially at low altitude.
Airworthiness Directives; GROB-WERKE Airplanes
We are superseding Airworthiness Directive (AD) 2014-26-04 for certain GROB-WERKE Models G115EG and G120A 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 a defective starter solenoid. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 and 747-400F series airplanes. This AD was prompted by reports of cracking in the main equipment center (MEC) drip shield and exhaust plenum. This AD requires installing a fiberglass reinforcing overcoat on the MEC drip shield. We are issuing this AD to prevent water penetration into the MEC, which could result in an electrical short and potential loss of several functions essential for safe flight.
Airworthiness Directives; Zodiac Aerotechnics (Formerly Intertechnique Aircraft Systems) Oxygen Mask Regulators
We are adopting a new airworthiness directive (AD) for certain Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems) oxygen mask regulators. This AD was prompted by a report of a malfunctioning mask having an inflatable harness with a high premature rupture rate due to defective silicon. This AD requires inspecting and replacing defective harnesses with new or modified serviceable units. We are issuing this AD to detect and correct defective harnesses, which could lead, in case of a sudden depressurization event, to a harness rupture, thereby providing inadequate protection against hypoxia and possibly resulting in unconsciousness of the affected flightcrew member and consequent reduced control of the airplane.
Prohibition Against Certain Flights Within the Baghdad (ORBB) Flight Information Region (FIR)
This action amends Special Federal Aviation Regulation (SFAR) No. 77, ``Prohibition Against Certain Flights Within the Territory and Airspace of Iraq,'' which prohibits certain flight operations in the territory and airspace of Iraq by all United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.-registered civil aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when such operators are foreign air carriers. On August 8, 2014, the FAA issued a Notice to Airmen (NOTAM) prohibiting flight operations in the ORBB FIR at all altitudes, subject to certain limited exceptions, due to the armed conflict in Iraq. This amendment to SFAR No. 77 incorporates the flight prohibition set forth in the August 8, 2014, NOTAM into the rule. The FAA is also revising the approval process for this SFAR for other U.S. Government departments, agencies, and instrumentalities, to align with the approval process established for other recently published flight prohibition SFARs. This final rule will remain in effect for two years.
Proposed Amendment of Class E Airspace for the Following Louisiana Towns: Jonesboro, LA and Winnfield, LA
This action proposes to amend Class E airspace at Jonesboro Airport, Jonesboro, LA, and David G. Joyce Airport, Winnfield, LA. Decommissioning of the non-directional radio beacons (NDB) and/or cancellation of NDB approaches due to advances in Global Positioning System (GPS) capabilities has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the above airports.
Proposed Amendment of Class E Airspace for the Following Nebraska Towns: Albion, NE; Bassett, NE; Lexington, NE
This action proposes to amend Class E airspace at Albion Municipal Airport, Albion, NE; Rock County Airport, Bassett, NE; and Jim Kelly Field Airport, Lexington, NE. Decommissioning of the non- directional radio beacons (NDB) and/or cancellation of NDB approaches due to advances in Global Positioning System (GPS) capabilities has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the above airports. Also, the geographic coordinates would be updated for Rock County Airport and Jim Kelly Field Airport.
Airworthiness Directives; BAE SYSTEMS (Operations) Limited Airplanes
We propose to supersede Airworthiness Directive (AD) 2011-21- 06 for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. AD 2011-21-06 currently requires revising the maintenance program. Since we issued AD 2011-21-06, we have determined that the life limit of certain main landing gear components must be reduced, and certain post- repair inspections of critical structure are necessary. This proposed AD would require a new revision of the maintenance/inspection program. We are proposing this AD to prevent failure of certain structurally significant items, including the main landing gear and nose landing gear, which could result in reduced structural integrity of the airplane; and to prevent fuel vapor ignition sources, which could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2004-14- 09, for certain Airbus Model A320-211, -212, and -231 airplanes. AD 2004-14-09 currently requires repetitive inspections for fatigue cracking of the lower surface panel on the wing center box, and repair if necessary; and modification of the lower surface panel on the wing center box, which constitutes terminating action for the repetitive inspections. Since we issued AD 2004-14-09, we have determined that, based on the average flight duration, the average weight of fuel at landing is higher than that defined for the analysis of the fatigue- related tasks; and that shot peening might have been improperly done on the chromic acid anodizing (CAA) protection, which would adversely affect fatigue crack protection. This proposed AD would reduce the compliance times for the repetitive inspections, and would require a repair for certain airplanes. We are proposing this AD to detect and correct fatigue cracking of the lower surface panel on the wing center box, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 series airplanes. This proposed AD was prompted by fatigue testing that determined fatigue damage could appear on clips, shear webs, and angles at certain rear fuselage sections and certain frames. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would require replacing the clips, the shear webs, and angles, including doing all applicable related investigative actions, and repair if necessary. We are proposing this AD to prevent fatigue damage on the clips, shear webs, and angles, which could affect the structural integrity of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes. This proposed AD was prompted by multiple reports of chafing found on an electrical wiring harness in the aft equipment bay, caused by contact between the wiring harness and a neighboring hydraulic line. This proposed AD would require an inspection, repair if necessary, and modification of the wiring harness installation to ensure that the wiring harness routing is correct and a minimum clearance between the wire and the hydraulic line is maintained. We are proposing this AD to detect and correct chafing on an electrical wiring harness, which could cause an electrical short circuit or lead to a malfunction of the flight control system, the engine indication system, or the hydraulic power control system, and adversely affect the continued safe operation and landing of the airplane.
Proposed Revocation of Class D and E Airspace; Independence, KS
This supplemental notice of proposed rulemaking proposes to remove Class D airspace and Class E surface area airspace at Independence Municipal Airport, Independence, KS. In an NPRM published in the Federal Register September 25, 2014, the FAA proposed to remove Class D airspace at Independence Municipal Airport, Independence, KS. The FAA has reassessed the proposal to include the removal of the associated Class E surface area airspace. The closure of the airport's air traffic control tower has necessitated the need for this proposal.
Proposed Establishment and Amendment of Class E Airspace; Bremerton, WA
This action proposes to establish and modify Class E airspace at Bremerton National Airport, Bremerton, WA, to accommodate new Standard Instrument Approach Procedures (SIAPs) at Bremerton National airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.

Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747- 200B, 747-300, 747SR, and 747SP series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that certain fuselage skin lap joints are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive post-modification inspections for cracking of the skin or internal doubler along the edge fastener rows of the modification, and repair if necessary. We are proposing this AD to detect and correct fatigue cracking in certain fuselage skin lap joints, which could result in rapid depressurization of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, -200B, -200C, -200F, -300, - 400, -400D, and -400F series airplanes. This proposed AD was prompted by reports of significant fuselage skin damage at certain parts of the dorsal fairing, due to wear from the dorsal fairing. This proposed AD would require repetitive detailed inspections for wear and cracks of the fuselage skin under the dorsal fairing, and related investigative and corrective actions if necessary. This proposed AD would also require repetitive post-repair external surface high frequency eddy current inspections of the blended areas of the skin and detailed inspections of the unrepaired areas, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct fuselage skin damage of the dorsal fairing area, which could result in skin cracking and consequent depressurization of the airplane.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments

These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
Airworthiness Directives; DG Flugzeugbau GmbH Gliders
We are adopting a new airworthiness directive (AD) for DG Flugzeugbau GmbH Model DG-1000T gliders equipped with a Solo Kleinmotoren Model 2350 C engine that supersedes AD 2013-22-14 R1. 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 engine shaft failure with consequent propeller detachment. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters (Type Certificate Previously Held by Eurocopter France)
We are adopting a new airworthiness directive (AD) for Airbus Model EC225LP helicopters. This AD requires repetitive visual and tap test inspections of each main rotor blade (blade) leading edge stainless steel protective strip (strip) for a crack, cut, or blind or open debonding (debonding), and taking approved corrective measures. If there is a crack or if there is debonding that exceeds acceptable limits, this AD requires, before further flight, repairing or replacing the blade with an airworthy part. This AD was prompted by suspected water seepage through a crack in the blade strip resulting in significant debonding. The actions of this AD are intended to prevent loss of the blade strip, excessive vibrations induced by blade weight imbalance, and subsequent loss of control of the helicopter.
Air Carrier Contract Maintenance Requirements; Correction
The FAA is correcting a final rule published on March 4, 2015 (80 FR 11537). In that rule, the FAA amended its maintenance regulations for domestic, flag, and supplemental operations, and for commuter and on-demand operations for aircraft type certificated with a passenger seating configuration of 10 seats or more (excluding any pilot seat). The FAA originally proposed to make the effective date of the rule one year after its publication date to give affected operators time to come into compliance with the new requirements, and to allow the FAA time to review information submitted by the operators under the rule. However, in the final rule, the FAA inadvertently overlooked the proposed one-year compliance time, and included an effective date of 60 days after publication. This document corrects the effective date of that document.
Airworthiness Directives; Fokker Services B.V. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.27 Mark 200, 300, 400, 500, 600, and 700 airplanes. This proposed AD was prompted by a design review, which revealed that no controlled bonding provisions are present on a number of critical locations inside the fuel tank or connected to the fuel tank wall; and no anti-spray cover is installed on the fuel shut-off valve (FSOV) in both wings. This proposed AD would require installing additional bonding provisions in the fuel tank, installing an anti- spray cover on the FSOV, and revising the airplane maintenance program by incorporating fuel airworthiness limitation items and critical design configuration control limitations. We are proposing this AD to prevent an ignition source in the fuel tank vapor space, which could result in a fuel tank explosion and consequent loss of the airplane.
