Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the gore web lap splices of the aft pressure bulkhead are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections of the gore webs, gore web lap splices, and repair webs, as applicable, of the aft pressure bulkhead, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We are revising an earlier notice of proposed rulemaking (NPRM) to supersede Airworthiness Directive (AD) 2014-12-13, which applies to all The Boeing Company Model 737-100, -200, -200C, -300, - 400, and -500 series airplanes. This action revises the NPRM by expanding the inspection area. This action also revises the NPRM by no longer proposing to supersede AD 2014-12-13. We are proposing this AD to address the unsafe condition on these products. 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; Lycoming Engines Reciprocating Engines
We are adopting a new airworthiness directive (AD) for certain models of Lycoming Engines reciprocating engines. This AD requires an inspection of connecting rods and replacement of affected connecting rod small end bushings.

Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the fuselage crown skin panels are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections, replacement, and applicable on- condition actions for certain fuselage crown skin panels. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2012-12- 12, for all Airbus Model A330-200, A330-200 Freighter, A330-300, A340- 200, and A340-300 series airplanes; and AD 2013-16-26 for all Airbus Model A330-200 Freighter, A330-200 and -300, and A340-200 and -300 series airplanes. AD 2012-12-12 requires repetitive inspections of the outer skin rivets of the cargo doors; repair if necessary; and other repetitive inspections. AD 2013-16-26 requires repetitive inspections of certain cargo doors, and repair if necessary. Since we issued AD 2012-12-12 and AD 2013-16-26, we have determined that a new inspection procedure is necessary to address the unsafe condition. This proposed AD would continue to require repetitive inspections and repair if necessary. This proposed AD would add a one-time inspection and adjustment of certain hook gaps; reinforcement of the door frame structure; related investigative and corrective actions if necessary; and a modification, which would allow deferring reinforcement of the cargo door structure. We are proposing this AD to address the unsafe condition on these products.

Amendment of Class D and E Airspace; Mosinee, WI
This action modifies Class E airspace extending up to 700 feet above the surface at Central Wisconsin Airport, Mosinee, WI, to accommodate new standard instrument approach procedures for instrument flight rules (IFR) operations at the airport. This action is necessary due to the decommissioning of the Mosinee outer marker (OM) and DANCI locator outer marker (LOM) and cancellation of the associated approaches, and enhances the safety and management of IFR operations at the airport. This action also updates the geographic coordinates of the airport and the Wausau VHF Omni-Directional Radio Range and Collocated Tactical Air Navigation (VORTAC). This proposal also updates the geographic coordinates in Class D and Class E surface area airspace, and makes an editorial change in the legal description by replacing Airport/Facility Directory with the term Chart Supplement.
Proposed Amendment of Class D and Class E Airspace; Pueblo, CO
This action proposes to amend Class D airspace, Class E surface area airspace, and Class E airspace upward from 700 feet above the surface at Pueblo Memorial Airport, Pueblo, CO. The part-time Notice to Airmen (NOTAM) information would be removed from Class E airspace designated as an extension. The geographic coordinates for Pueblo Memorial Airport in the associated Class D and E airspace areas also would be amended to match the FAA's aeronautical database. A biennial review found these changes are necessary to accommodate airspace redesign for the safety and management of Instrument Flight Rules (IFR) operations within the National Airspace System. Also, an editorial change would be made to the Class D and Class E airspace legal descriptions replacing ``Airport/Facility Directory'' with the term ``Chart Supplement.''
Establishment of Class E Airspace, and Amendment of Class E Airspace; St. George, UT
This action establishes Class E airspace designated as an extension to a Class E surface area, establishes Class E en route airspace, and modifies Class E airspace extending upward from 700 feet above the surface at St. George Regional Airport (formerly St. George Municipal Airport), St. George, UT. After a review of the airspace, the FAA found redesign necessary to support new instrument flight rules (IFR) standard instrument approach procedures and en route operations where the Federal airway structure is inadequate, for the safety and management of aircraft operations at the airport. Also, this action updates the airport name from St. George Municipal Airport, to St. George Regional Airport, in the associated Class E airspace areas.
Temporary Flight Restrictions in the Proximity of Launch and Reentry Operations; Withdrawal
The FAA is withdrawing a previously published NPRM that proposed to revise the temporary flight restriction (TFR) provision for space flight operations to make the restrictions applicable to all aircraft including non-U.S. registered aircraft, instead of only U.S. registered aircraft or aircraft flown by pilots using a FAA pilot certificate. The NPRM also proposed to amend language for consistency with other TFR provisions and commercial space regulations and definitions by replacing ``space flight operations'' with ``launch, reentry, or amateur rocket operations.'' The intended effect of the proposed action was to further enhance the safety in the affected airspace and improve the readability of the TFR requirements. After further review of this action and the changing technology and scope of new flight operations, the FAA determined that a better assessment of TFRs in the National Air Space (NAS) is needed to address present day operations; therefore, it is withdrawing this NPRM.
Proposed Modification and Revocation of Multiple Air Traffic Service (ATS) Routes; Northcentral United States
This action proposes to amend and remove multiple VHF Omnidirectional Range (VOR) Federal airways in northcentral United States to reflect additional amendments to several Federal airways impacted by the decommissioning of the Tiverton, OH, VOR/Distance Measuring Equipment (VOR/DME) navigation aid. The route changes would be made as part of the FAA's Next Generation Air Transportation System (NextGen) efforts to safely improve the overall efficiency of the National Airspace System (NAS).
Airworthiness Directives; Honeywell International Inc. Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain Honeywell International Inc. AS907 series turbofan engines. This proposed AD was prompted by two loss-of-thrust-control events, and two in-flight shutdowns (IFSDs) of new production, low-time engines attributed to water intrusion of the engine electronic control unit (ECU). This proposed AD would require applying sealant to identified areas of the ECU and requires inserting a copy of certain airplane operating procedures into the applicable flight manuals. We are proposing this AD to correct the unsafe condition on these products.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures (ODPs) 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 safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 2012-21- 04, which applies to all Airbus Model A300 series airplanes; Model A310 series airplanes; and 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 2012-21-04 currently requires repetitive inspections for, and replacement of, any cracked hood halves of fuel pump canisters. Since we issued AD 2012-21-04, we allowed inspections of the outer tank and trim tank fuel pump canister hood halves to be terminated. However, we have received reports of new in-service events of outer tank fuel pump canister hood cracking. This proposed AD would retain the requirements of AD 2012-21-04, reinstate the terminated inspections, and add optional terminating actions. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; SOCATA Airplanes
We are superseding Airworthiness Directive (AD) 2002-19-01 for SOCATA Model TBM 700 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 the flight control wheel traveling beyond normal roll control limits and jamming in a position that could cause loss of control. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Agusta S.p.A. Helicopters
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. Model A109S helicopters. This AD requires adding limitations to the rotorcraft flight manual (RFM). This AD was prompted by a report of a cabin liner detaching from the helicopter and hitting the main rotor (M/R) blades during flight. The actions of this AD are intended to prevent an unsafe condition on these products.
Special Conditions: LifePort, Inc.: Boeing Model 747-8 Airplane; Single- and Multiple-Occupant Side-Facing Seats
These special conditions are issued for the Boeing Model 747-8 airplane. This airplane, as modified by LifePort Inc. (LifePort), will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport- category airplanes. These design features are single- and multiple- occupant side-facing seats (i.e., seats positioned in the airplane with the occupant facing 90 degrees to the direction of airplane travel). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Amendment of Class D and E Airspace; Kenosha, WI
This action modifies Class D airspace, Class E airspace designated as a surface area, and Class E airspace extending upward from 700 feet above the surface, and removes Class E airspace designated as an extension of Class D airspace at Kenosha Regional Airport, Kenosha, WI. This action is required due to the decommissioning of the Kenosha VHF omnidirectional range (VOR), which provided navigation guidance for portions of the affected routes. This action enhances the safety and management of instrument flight rules (IFR) operations at the airport. Also, the airport name and geographic coordinates are adjusted in the Class E airspace extending upward from 700 feet above the surface.
Proposed Establishment Class E Airspace; Cisco, TX

This AD was prompted by a report of airplanes with modified gust lock levers that prevented the thrust lever's full excursion, thus limiting the engine power. This AD requires replacing a certain gust lock lever. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Diamond Aircraft Industries GmbH Airplanes
We are adopting a new airworthiness directive (AD) for certain Diamond Aircraft Industries GmbH Model DA 42 airplanes. This AD requires installing engine exhaust pipe clamps with spring washers, repetitively inspecting the engine exhaust pipe clamps for cracks, and replacing the clamps if found cracked. This AD was prompted by cracks in the affected engine exhaust pipes, which could cause failure of the propeller regulating valve because of hot exhaust gases coming from the fractured pipes. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc. (Type Certificate Previously Held by Canadair Limited) Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-215-6B11 (CL-415 Variant) airplanes. This AD was prompted by a report indicating that an oxygen bottle was found loose while the clamp strap was in the locked position. This AD requires modification of the clamp strap and installation of additional shims, as applicable, to the flight crew's oxygen bottles' retaining structures. We are issuing this AD 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 787-9 airplanes. This AD was prompted by a determination that the shoulder bolt used on the outboard clevis of the forward support fitting of the ram air turbine (RAT) might not be long enough to allow for proper installation of the RAT; therefore, the clevis of the joint could be clamped together, resulting in reduced fatigue life and possible fracture of the clevis. This AD requires inspecting for cracking of the clevis of the forward support fitting of the RAT, installing a longer shoulder bolt, and replacing the forward support fitting if any cracking is found. We are issuing this AD 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 737-300, -400, and -500 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the lower skin at the skin lap splice lower fastener row is subject to widespread fatigue damage (WFD). This AD requires repetitive inspections for cracking in the skin lap splice at the lower fastener row, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
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.
