Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.
Pearson Field Airport Special Flight Rules Area
The FAA is proposing to establish a Special Flight Rules Area in the vicinity of Pearson Field Airport, Vancouver, Washington. Pearson Field Airport is located approximately three nautical miles northwest of Portland International Airport, Portland, Oregon. The close proximity of the airport traffic patterns and approach courses create converging flight paths between traffic on approach to Portland International Airport and traffic at Pearson Field Airport, increasing the risk for near mid-air collision, mid-air collision and wake turbulence events. The intended effect of this action is to mitigate the identified risk by establishing operating requirements applicable to all aircraft when operating within a designated area at Pearson Field Airport, which would increase overall system efficiency and safety.
Airspace Designations; Incorporation by Reference Amendments
This action incorporates certain amendments into FAA Order 7400.9Z, dated August 6, 2015, and effective September 15, 2015, for incorporation by reference in 14 CFR 71.1.
Amendment of Class D and Class E Airspace; Stockton, CA
This action modifies Class D airspace, Class E surface area airspace, and Class E airspace extending upward from 700 feet above the surface, at Stockton Metropolitan Airport, Stockton, CA. A review of the airspace and the decommissioning of the Manteca VHF omnidirectional radio range and distance measuring equipment (VOR/DME), has made it necessary to amend the airspace areas for the safety and management of the new Standard Instrument Approach Procedures (SIAPs) for Instrument Flight Rules (IFR) operations at the airport.
Special Conditions: Cessna Airplane Company Model 680A Airplane, Side-Facing Seats Equipped With Airbag Systems
These special conditions are issued for the Cessna Model 680A airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design features side- facing seats equipped with airbag systems. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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.
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 the upper chords of the upper deck floor beams are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections for cracks at the floor panel attachment fastener holes; repetitive inspections for cracks in the upper and lower chords of the upper deck floor beams at permanent fastener locations; repetitive inspections for cracks in certain repaired and modified areas; and related investigative and corrective actions if necessary. This proposed AD would also require repetitive replacement of the upper chords of the upper deck floor beams, including pre- replacement inspections and corrective action if necessary; and post- replacement repetitive inspections and repair if necessary. We are proposing this AD to detect and correct fatigue cracking of the upper chords of the upper deck floor beams. Undetected cracking could result in large deflection or deformation of the upper deck floor beams, resulting in damage to wire bundles and control cables for the flight control system, and reduced controllability of the airplane. Multiple adjacent severed floor beams could result in rapid decompression of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 717-200 airplanes. This proposed AD was prompted by multiple reports of the vertical stabilizer leading edge showing signs of fastener distress. This proposed AD would require a detailed inspection for any distress of the vertical stabilizer leading edge skin, and related investigative and corrective actions, if necessary. This proposed AD would also require, for certain airplanes, repetitive detailed inspections of the spar cap for any loose and missing fasteners, repetitive high frequency eddy current (HFEC) and radiographic testing (RT) inspections of the spar cap for any crack, and related investigative and corrective actions, if necessary. We are proposing this AD to detect and correct any crack in the vertical stabilizer leading edge and front spar cap, which may result in the structure becoming unable to support limit load, and may lead to the loss of the vertical stabilizer.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by a determination that no instructions for continued airworthiness exist for the nose landing gear (NLG) alternate extension actuator of the NLG alternate release system. This AD requires revising the maintenance or inspection program, as applicable, to incorporate a new airworthiness limitation task for the NLG alternate extension actuator. We are issuing this AD to prevent failure of the NLG alternate release system and, if the normal NLG extension system also fails, failure of the NLG to extend, and consequent damage to the airplane and injury to occupants.
Airworthiness Directives; Viking Air Limited (Type Certificate Previously Held by Bombardier, Inc.) Airplanes
We are adopting a new airworthiness directive (AD) for all Viking Air Limited (Type Certificate Previously Held by Bombardier, Inc.) Model DHC-7-1 and DHC-7-100 airplanes. This AD was prompted by reports of cracks that were discovered in the outboard nacelles upper longeron channels and angles. This AD requires a one-time detailed visual inspection for cracking in the outboard nacelles upper longeron channels and angles; and repair if necessary. We are issuing this AD to detect and correct cracks in the outboard nacelles upper longeron channels and angles, which could lead to the loss of stiffness in the forward engine mount; and possible catastrophic failure.
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 amends 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 (NDBs) 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.
