Notice of Availability of Purpose, Need, and Alternatives Working Paper for the Proposed Airfield Safety Enhancement Project and Real Property Transactions, Tucson International Airport, Tucson, Pima County, Arizona
The Federal Aviation Administration (FAA) has prepared the Purpose, Need, and Alternatives Working Paper for the Proposed Airfield Safety Enhancement Project (ASEP) including real property transactions at Tucson International Airport (TUS), Pima County, Arizona. The FAA initiated preparation of an Environmental Impact Statement (EIS) in response to a proposal by the Tucson Airport Authority (TAA). The FAA is issuing this notice to advise the public that the Purpose, Need, and Alternatives Working Paper will be made available for public comment as part of a continued effort to engage the public in the scoping process for this project. FAA is seeking comments on the Working Paper. The FAA is the lead Federal agency for preparation of the EIS and will do so in compliance with the National Environmental Policy Act (NEPA) of 1969, as amended (42 U.S.C. 4321 et seq.) and Council on Environmental Quality (CEQ) Regulations for Implementing the Procedural Provisions of NEPA (40 CFR parts 1500-15080). The preparation of the EIS will follow FAA regulations and policies for implementing NEPA published in FAA Order 1050.1F, Environmental Impacts: Policies and Procedures, and FAA Order 5050.4B, National Environmental Policy Act (NEPA) Implementing Instructions for Airport Actions. The U.S. Air Force (USAF) and the National Guard Bureau (NGB) are cooperating agencies under 40 CFR 1501.6. This Purpose, Need, and Alternatives Working Paper provides background information on TUS, a description of the Proposed Action, and the Purpose and Need to which the FAA, USAF, and NGB are responding in evaluating the Proposed Action and various reasonable alternatives to the Proposed Action. In whole or in summary, the Purpose, Need, and Alternatives Working Paper will become part of the EIS. The FAA is not making a decision regarding the Proposed Action in this Working Paper.
Airworthiness Directives; Textron Aviation Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Textron Aviation Inc. Models A36TC and B36TC airplanes. This proposed AD was prompted by a fatal accident where the exhaust tailpipe fell off during takeoff. This proposed AD would add a life limit to the exhaust tailpipe v-band coupling (clamp) that attaches the exhaust tailpipe to the turbocharger and, if the coupling is removed for any reason before the life limit is reached, this proposed AD would require an inspection of the coupling before reinstalling. We are proposing this AD to correct the unsafe condition on these products.
Special Conditions: Bombardier Inc. Model BD-700-2A12 and BD-700-2A13 Airplanes; Fuselage In-Flight Fire Safety and Flammability Resistance of Aluminum-Lithium Material
These special conditions are issued for the Bombardier Inc. (Bombardier) Model BD-700-2A12 and BD-700-2A13 airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is a fuselage fabricated using aluminum-lithium materials instead of conventional aluminum. The applicable airworthiness regulations do not contain adequate or appropriate fire-safety standards for this design feature. These special conditions contain the additional fire-safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding Airworthiness Directive (AD) 2015-03-01, for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2015-03-01 required installing additional attaching hardware on the left and right engine fan cowl access panels and the nacelle attaching structures. This new AD requires weight and balance data to be included in the Weight and Balance Manual for certain modified airplanes. This new AD also requires the weight and balance data to be used in order to calculate the center of gravity for affected airplanes. This AD was prompted by updates to the weight and balance data needed to calculate the center of gravity for affected airplanes. 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, and -106 airplanes; and Model DHC-8-200 and DHC-8-300 series airplanes. This AD was prompted by reports of incorrect installation of the auto-ignition system due to crossed wires at one of the splices in the auto-relight system. This AD requires inspecting the auto-ignition system for correct wiring, and doing corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
We are superseding Airworthiness Directive (AD) 2013-22-19 for all Gulfstream Aerospace Corporation Model GV and GV-SP airplanes. AD 2013-22-19 required inspecting to determine if fuel boost pumps having a certain part number were installed, replacing the fuel boost pumps having a certain part number, and revising the airplane maintenance program to include revised Instructions for Continued Airworthiness. This new AD reduces the compliance time for revising the airplane maintenance or inspection program. This AD was prompted by reports of two independent types of failure of the fuel boost pump with overheat damage found on the internal components and external housing on one of the failure types, and fuel leakage on the other. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; American Champion Aircraft Corp.
We are adopting a new airworthiness directive (AD) for certain American Champion Aircraft Corp. Model 8KCAB airplanes. This AD requires fabrication and installation of a placard to prohibit aerobatic flight, inspection of the aileron hinge rib and support, and a reporting requirement of the inspection results to the FAA. This AD was prompted by a report of a cracked hinge support and cracked hinge ribs, which resulted in partial loss of control with the aileron binding against the cove. We are issuing this AD to correct the unsafe condition on these products.
