Proposed Establishment of Class E Airspace; Clark, SD
This action proposes to establish Class E airspace at Clark, SD. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Clark County Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.
Notice of Intent To Rule on Request To Release Airport Property at the Dubois Regional Airport, Reynoldsville, Pennsylvania
The FAA proposes to rule and invite public comment on the release of land at the Dubois Regional Airport, Reynoldsville, Pennsylvania under the provision 49 U.P.C. 47125(a).
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-524 turbofan engines with certain part number (P/N) low-pressure turbine (LPT) stage 3 turbine blades installed. This proposed AD was prompted by reports of LPT stage 3 turbine blade failures, release of blades, and subsequent in-flight shutdowns. This proposed AD would require implementation of a life limit for certain P/N LPT stage 3 turbine blades and replacement of affected blades that reach or exceed the life limit. We are proposing this AD to prevent failure of LPT stage 3 turbine blades and subsequent release of blade debris, which could lead to failure of one or more engines, loss of thrust control, and damage to the airplane.
Airworthiness Directives; Dowty Propellers Constant Speed Propellers
We are revising airworthiness directive (AD) 2010-17-11R1, which applies to all Dowty Propellers R408/6-123-F/17 model propellers. AD 2010-17-11R1 required initial application of sealant between the bus bar assembly and the backplate assembly of certain line-replaceable units (LRUs) and repetitive re-applications of sealant on all R408/6- 123-F/17 model propellers. AD 2010-17-11R1 also provided an optional terminating action to the repetitive re-application of sealant. This AD increases the interval allowed between the required re-application of sealant, and specifies an additional acceptable sealant. This AD was prompted by failure of the propeller de-ice bus bar due to friction or contact between the bus bar and the backplate assembly, consequent intermittent short circuit, and possible double generator failure. We are issuing this AD to prevent an in-flight double generator failure, which could result in reduced control of the airplane.
Notice of Passenger Facility Charge (PFC) Approvals and Disapprovals
The FAA publishes a monthly notice, as appropriate, of PFC approvals and disapprovals under the provisions of the Aviation Safety and Capacity Expansion Act of 1990 (Title IX of the Omnibus Budget Reconciliation Act of 1990) (Pub. L.101-508) and Part 158 of the Federal Aviation Regulations (14 CFR part 158). This notice is published pursuant to paragraph d of Sec. 158.29.
Establishment of Class D and E Airspace, and Amendment of Class E Airspace; Hammond, LA
This action establishes Class D airspace and Class E airspace designated as an extension, at Hammond, LA. The establishment of an air traffic control tower has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations within the airspace at Hammond Northshore Regional Airport. This action also amends the airport name and adjusts the geographic coordinates for the current Class E airspace area.
Proposed Establishment of Class E Airspace; Tucumcari, NM
This action withdraws the NPRM published in the Federal Register on December 20, 2013. In that action, the FAA proposed to establish Class E airspace at the Tucumcari VORTAC, Tucumcari, NM. The FAA has determined that withdrawal of the NPRM is warranted as a result of objections raised during the comment period.
Amendment of Class E Airspace; Roanoke Rapids, NC
This action amends Class E Airspace at Roanoke Rapids, NC, as Halifax County Airport has been abandoned, no longer requiring controlled airspace.
Amendment of Class E Airspace; Apalachicola, FL
This action amends Class E Airspace at Apalachicola, FL, as Apalachicola Municipal Airport has been renamed Apalachicola Regional Airport. This action also updates the geographic coordinates of the airport.
Amendment of Class D Airspace; MacDill AFB, FL
This action amends Class D Airspace at MacDill AFB, FL, by adding the words ``to but not including 1,200 feet MSL,'' further clarifying the ceiling in the descriptor of the Class D airspace. This action does not change the boundaries or operating requirements of the airspace.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are superseding airworthiness directive (AD) 98-07-07 for all Rolls-Royce plc (RR) RB211-535E4 and RB211-535E4-B turbofan engines. AD 98-07-07 required removing certain part number (P/N) low- pressure (LP) fuel filter-to-high-pressure (HP) fuel pump tube assemblies and installing flexible LP fuel filter-to-HP fuel pump tube assemblies. This AD expands the applicability of AD 98-07-07 to include the RB211-535E4-C-37 turbofan engine and requires removal from service of additional P/N LP fuel filter-to-high-pressure HP fuel pump tube assemblies. This AD was prompted by reports of fuel leaks that have resulted in a number of engine in-flight shutdowns. We are issuing this AD to prevent loss of fuel supply to the engine, which could lead to an in-flight shutdown of one or more engines, loss of thrust control, and damage to the airplane.
Airworthiness Directives; Various de Havilland Airplanes
We are adopting a new airworthiness directive (AD) for all Harry E. Williams de Havilland Model DH 82A airplanes, all Cliff Robertson de Havilland Model DH 82A airplanes, and all de Havilland Model DH 83 airplanes. This AD was prompted by reports of structural failure of the attachment of the wing to the fuselage that resulted from failed lateral fuselage tie rods. This AD requires inspecting the aircraft maintenance records to determine the date of installation or the date of last replacement of the lateral fuselage tie rods. This AD also requires repetitively replacing all lateral fuselage tie rods and attaching nuts at a specified life limit interval. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2013-20-06 for all Airbus Model A340-211, -212, -213, -311, -312, -313, -541, and -642 airplanes. AD 2013-20-06 required revising the maintenance program to incorporate certain maintenance requirements and airworthiness limitations. This new AD requires revising the maintenance or inspection program to incorporate certain other maintenance requirements and airworthiness limitations. This AD was prompted by a determination that existing maintenance requirements are not adequate to address the aging effects of aircraft systems. We are issuing this AD to address the aging effects of aircraft systems. Such aging effects could change the characteristics of systems' life-limited components leading to an increased potential for failure, which, in isolation or in combination with one or more other specific failures or events, could result in failure of certain life limited parts, which could reduce the structural integrity or the controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2008-17-03 for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. AD 2008-17-03 required repetitive inspections to detect fuselage frame cracking, and corrective action if necessary. AD 2008-17-03 also provided for optional terminating action (repair/ preventive change) for the repetitive inspections. This new AD adds airplanes to the applicability, but does not provide terminating action for the newly added airplanes. This AD was prompted by reports of cracks found at the cutout in the web of body station frame 303.9 inboard of stringer 16L, as well as a new report of cracking found on an airplane not identified in the applicability of AD 2008-17-03. We are issuing this AD to detect and correct fuselage frame cracking, which could prevent the left forward entry door from sealing correctly, and could cause in-flight decompression of the airplane.
