Federal Aviation Administration September 13, 2012 – Federal Register Recent Federal Regulation Documents

Proposed Amendment of Class E Airspace; Gaylord, MI
Document Number: 2012-22599
Type: Proposed Rule
Date: 2012-09-13
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to amend Class E airspace at Gaylord, MI. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAP) at Gaylord Regional Airport. Also, this action would rename the airport and update the geographic coordinates. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.
Air Traffic Procedures Advisory Committee
Document Number: 2012-22575
Type: Notice
Date: 2012-09-13
Agency: Federal Aviation Administration, Department of Transportation
The FAA is issuing this notice to advise the public that a meeting of the Federal Aviation Administration Air Traffic Procedures Advisory Committee (ATPAC) will be held to review present air traffic control procedures and practices for standardization, revision, clarification, and upgrading of terminology and procedures.
Airworthiness Directives; Various Restricted Category Helicopters
Document Number: 2012-22564
Type: Rule
Date: 2012-09-13
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for various restricted category Model HH-1K, TH-1F, TH-1L, UH-1A, UH-1B, UH-1E, UH- 1F, UH-1H, UH-1L, and UH-1P helicopters with certain main rotor (M/R) blade assemblies installed, to require inspecting the grip plates, doublers, and upper and lower surfaces of the M/R blades in the area between blade stations 24.5 and 40 for an edge void, corrosion, or a crack. This AD is prompted by several reports of fatigue cracks on M/R blades installed on Bell Helicopter Textron, Inc. (Bell) Model 212 helicopters. These same part-numbered M/R blades may also be installed on certain FAA-approved modified restricted category helicopters. These actions are intended to detect an edge void, corrosion, or a crack on an M/R blade, which could lead to loss of the M/R blade and subsequent loss of control of the helicopter.
Airworthiness Directives; Turbomeca S.A. Turboshaft Engines
Document Number: 2012-22530
Type: Proposed Rule
Date: 2012-09-13
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Turbomeca S.A. Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines. This proposed AD was prompted by several reports of uncommanded in-flight shutdown (IFSD) on Arriel 1 engines. This proposed AD would require performing a high gas generator speed (NG) rating vibration check. We are proposing this AD to prevent an uncommanded in-flight shut-down of the engine, which could result in an emergency landing.
Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
Document Number: 2012-22525
Type: Proposed Rule
Date: 2012-09-13
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for the Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopter, which proposed revising the Rotorcraft Flight Manual (RFM), Operating Limitations section, to prohibit Class D external load operations, including human external cargo (HEC), because this model helicopter was not certificated to one-engine inoperative performance standards for carrying Class D external loads. This Supplemental NPRM is prompted by a recent design approval, which allows Class D external load operations if the appropriate operating limitations are included in the RFM. This proposed AD is intended to require appropriate operating limitations to allow operators to perform Class D external load-combination operations, including HEC, in this model helicopter that now meets the Category A performance standard.
Special Conditions: Bombardier, Model CL-600-2B16 Airplane (CL-601-3A, CL-601-3R, and CL-604 Variants); Enhanced Flight Vision System
Document Number: 2012-22468
Type: Rule
Date: 2012-09-13
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Bombardier Model CL-600-2B16 airplanes, including variants CL-601-3A, CL-601-3R and CL- 604. This airplane, as modified by Atlantic Aero, Inc., will have a novel or unusual design feature associated with an advanced, enhanced flight vision system (EFVS). The EFVS consists of a head-up display (HUD) system modified to display forward-looking infrared (FLIR) imagery. 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.
