Federal Aviation Administration December 11, 2014 – Federal Register Recent Federal Regulation Documents

IFR Altitudes; Miscellaneous Amendments
Document Number: 2014-29074
Type: Rule
Date: 2014-12-11
Agency: Federal Aviation Administration, Department of Transportation
This amendment adopts miscellaneous amendments to the required IFR (instrument flight rules) altitudes and changeover points for certain Federal airways, jet routes, or direct routes for which a minimum or maximum en route authorized IFR altitude is prescribed. This regulatory action is needed because of changes occurring in the National Airspace System. These changes are designed to provide for the safe and efficient use of the navigable airspace under instrument conditions in the affected areas.
Special Conditions: AAR Engineering Services, Boeing 757-200 Series Airplane; Seats With Non-Traditional, Large, Non-Metallic Panels
Document Number: 2014-29029
Type: Rule
Date: 2014-12-11
Agency: Federal Aviation Administration, Department of Transportation
These special conditions are issued for the Boeing 757-200 series airplane. This airplane, as modified by AAR Engineering Services, 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 feature includes seats with non-traditional, large, non-metallic panels on Boeing 757-200 series airplanes. 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.
Harmonization of Airworthiness Standards-Gust and Maneuver Load Requirements
Document Number: 2014-28938
Type: Rule
Date: 2014-12-11
Agency: Federal Aviation Administration, Department of Transportation
This final rule amends certain airworthiness regulations for transport category airplanes, based on recommendations from the FAA- sponsored Aviation Rulemaking Advisory Committee (ARAC). This amendment eliminates regulatory differences between the airworthiness standards of the FAA and European Aviation Safety Agency (EASA). It does not add new requirements beyond what manufacturers currently meet for EASA certification and does not affect current industry design practices. This final rule revises the pitch maneuver design loads criteria; revises the gust and turbulence design loads criteria; revises the application of gust loads to engine mounts, high lift devices, and other control surfaces; adds a ``round-the-clock'' discrete gust criterion and a multi-axis discrete gust criterion for airplanes equipped with wing-mounted engines; revises the engine torque loads criteria; adds an engine failure dynamic load condition; revises the ground gust design loads criteria; revises the criteria used to establish the rough air design speed; and requires the establishment of a rough air Mach number.
