Federal Aviation Administration October 20, 2011 – Federal Register Recent Federal Regulation Documents

Special Conditions: Gulfstream Aerospace Corporation, Model GIV-X Airplane; Isolation or Aircraft Electronic System Security Protection From Unauthorized Internal Access
Document Number: 2011-27198
Type: Rule
Date: 2011-10-20
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Gulfstream Aerospace Corporation Model GIV-X airplane. This airplane will have novel or unusual design features associated with connectivity of the passenger domain computer systems to the airplane critical systems and data networks. 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.
Special Conditions: Gulfstream Aerospace Corporation, Model GIV-X Airplane; Aircraft Electronic System Security Protection From Unauthorized External Access
Document Number: 2011-27196
Type: Rule
Date: 2011-10-20
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Gulfstream Aerospace Corporation Model GIV-X airplane. This airplane will have novel or unusual design features associated with the architecture and connectivity capabilities of the airplane's computer systems and networks, which may allow access by external computer systems and networks. Connectivity by external systems and networks may result in security vulnerabilities to the airplane's systems. 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.
Special Conditions: Embraer S.A.; Model EMB 500; Single-Place Side Facing Seat Dynamic Test Requirements
Document Number: 2011-27119
Type: Rule
Date: 2011-10-20
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the installation of a single-place side facing seat on Embraer S.A. EMB 500 aircraft. Side- facing seats are considered a novel design, and their installation in a part 23 airplane was not envisaged and is not adequately addressed in 14 CFR part 23. The FAA has determined that the existing regulations do not provide adequate or appropriate safety standards for occupants of single-place side-facing seats. In order to provide a level of safety that is equivalent to that afforded to occupants of forward and aft facing seating, additional airworthiness standards, in the form of special conditions, are necessary.
Amendment of Federal Airways; Alaska
Document Number: 2011-27118
Type: Rule
Date: 2011-10-20
Agency: Federal Aviation Administration, Department of Transportation
This action removes two modified VHF Omnidirectional Range (VOR) Federal airways, V-320 and V-440, from a final rule published in the Federal Register of April 28, 2011. That rule amended 29 Air Traffic Service (ATS) routes in Alaska affected by the relocation of the Anchorage VOR navigation aid. The FAA is taking this action as a result of these VOR Federal airways not passing flight inspections to retain existing minimum enroute altitude (MEA) requirements in the vicinity of Anchorage, AK.
Membership Availability in the National Parks Overflights Advisory Group Aviation Rulemaking Committee-Representative of Native American Tribes
Document Number: 2011-27091
Type: Notice
Date: 2011-10-20
Agency: Federal Aviation Administration, Department of Transportation
The National Park Service (NPS) and the Federal Aviation Administration (FAA), as required by the National Parks Air Tour Management Act of 2000, established the National Parks Overflights Advisory Group (NPOAG) in March 2001. The NPOAG was formed to provide continuing advice and counsel with respect to commercial air tour operations over and near national parks. This notice informs the public of a vacancy (due to completion of membership on April 2, 2012) on the NPOAG (now the NPOAG Aviation Rulemaking Committee (ARC)) for a representative of Native American tribal concerns and invites interested persons to apply to fill the vacancy.
Airworthiness Directives; Rolls-Royce plc (RR) Turbofan Engines
Document Number: 2011-27069
Type: Proposed Rule
Date: 2011-10-20
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to all RR model RB211-524G2-T-19, -524G3-T-19, -524H- T-36, and -524H2-T-19; and RB211-Trent 553-61, 553A2-61, 556-61, 556A2- 61, 556B-61, 556B2-61, 560-61, 560A2-61; RB211-Trent 768-60, 772-60, 772B-60; and RB211-Trent 875-17, 877-17, 884-17, 884B-17, 892-17, 892B- 17, and 895-17 turbofan engines that have a high-pressure (HP) compressor stage 1 to 4 rotor disc with a part number (P/N) listed in Table 1 of this proposed AD. The existing AD currently requires repetitive inspections of the axial dovetail slots, and follow-on corrective action depending on findings. Since we issued that AD, we determined that the definition of shop visit is too restrictive in the existing AD. This proposed AD would continue to require those repetitive inspections and follow-on corrective actions, and it would change the definition of a shop visit to be less restrictive. We are proposing this AD to detect cracks in the HP compressor stage 1 and 2 disc posts, which could result in failure of the disc post and HP compressor blades, release of uncontained engine debris, and damage to the airplane.
