Federal Aviation Administration March 27, 2012 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Fokker Services B.V. Airplanes
Document Number: 2012-7361
Type: Proposed Rule
Date: 2012-03-27
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by a design review which revealed the absence of electrical insulation material between a wing or integral center wing tank (ICWT) fuel quantity indication system (FQIS) probe and the bottom of the tank structure. This condition, if not corrected, could, under certain conditions, result in an ignition source in the tank vapor space, which could result in a fuel tank explosion and consequent loss of the airplane. This proposed AD would require, for all airplanes, applying sealant below the FQIS probes in the wing tanks; and for certain airplanes, applying sealant below the FQIS probes in the ICWT. This proposed AD would also require revising the aircraft maintenance program by revising the fuel airworthiness limitations and incorporating critical design configuration control limitations (CDCCLs). We are proposing this AD to prevent an ignition source in the tank vapor space, which could result in a fuel tank explosion and consequent loss of the airplane.
Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2012-7357
Type: Proposed Rule
Date: 2012-03-27
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-400, -401, and -402 airplanes. This proposed AD was prompted by reports of cracking of certain fuel access panels of the outer wing. This proposed AD would require an external inspection, and if necessary an internal inspection, to determine if certain fuel access panels are installed, and replacement if necessary; optional repetitive inspections for cracking of the fuel access panels, and replacement if necessary, would defer the internal inspection; and eventual replacement of affected fuel access panels with new panels. We are proposing this AD to prevent cracking of fuel access panels, which could result in arcing and ignition of fuel vapor in the outer wing fuel tank during a lightning strike.
Air Traffic Noise, Fuel Burn, and Emissions Modeling Using the Aviation Environmental Design Tool Version 2a
Document Number: 2012-7354
Type: Notice
Date: 2012-03-27
Agency: Federal Aviation Administration, Department of Transportation
This document provides a statement of FAA policy concerning the required use of the Aviation Environmental Design Tool version 2a (AEDT 2a) to analyze noise, fuel burn, and emissions for FAA air traffic airspace and procedure actions where the study area is larger than the immediate vicinity of an airport, incorporates more than one airport, or includes actions above 3,000 feet above ground level (AGL). The policy statement is intended to ensure consistency and quality of analysis performed to assess noise, fuel burn, and emissions impacts of such actions under the National Environmental Policy Act of 1969 (NEPA), as amended, 42 United States Code (U.S.C.) Sec. Sec. 4321 et seq.
Amendment of Restricted Areas R-5801 and R-5803; Chambersburg, PA
Document Number: 2012-7311
Type: Rule
Date: 2012-03-27
Agency: Federal Aviation Administration, Department of Transportation
This action makes a minor editorial change to the time of designation for restricted areas R-5801 and R-5803, Chambersburg, PA, to remove the abbreviation ``EST.'' This amendment does not change the dimensions of, or activities conducted within, the restricted areas.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-7283
Type: Proposed Rule
Date: 2012-03-27
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Boeing Model 747-100, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400F, and 747SR series airplanes. This proposed AD was prompted by reports of broken and damaged latch pin retention bolts of the main deck side cargo door (MDSCD), latch pin migration, and broken latch pin fittings. This proposed AD would require various repetitive inspections of the MDSCD latch pin fittings, measuring the latch pin, and related investigative and corrective actions if necessary; and modifying the latch pin fittings and installing new latch pins and latch pin fasteners. We are proposing this AD to prevent loss of the cargo door and rapid depressurization of the airplane.
Special Conditions: Dassault Aviation, Model Falcon 7X Airplanes; Seats With Inflatable Shoulder Straps
Document Number: 2012-7280
Type: Rule
Date: 2012-03-27
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Dassault Aviation Model Falcon 7X airplane. This airplane will have a novel or unusual design feature associated with seats with inflatable shoulder straps. 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.
Amendment of Class E Airspace; Lamar, CO
Document Number: 2012-7231
Type: Rule
Date: 2012-03-27
Agency: Federal Aviation Administration, Department of Transportation
This action amends Class E airspace at Lamar Municipal Airport, Lamar, CO. Decommissioning of the Lamar Tactical Air Navigation System (TACAN) has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also adjusts the geographic coordinates of the airport.
Establishment of Class E Airspace; Piseco, NY
Document Number: 2012-7230
Type: Rule
Date: 2012-03-27
Agency: Federal Aviation Administration, Department of Transportation
This action establishes Class E airspace at Piseco, NY, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures at Piseco Airport. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also makes a minor adjustment to the geographic coordinates of the airport.
