Department of Transportation April 10, 2014 – Federal Register Recent Federal Regulation Documents

This is notification of criteria used to evaluate the Waypoint 2 Space, Inc. (W2S) safety approval application. The FAA issued W2S a safety approval, subject to the provisions of Title 51 U.S.C Subtitle V, ch. 509, and the orders, rules and regulations issued under it. Pursuant to Title 14 Code of Federal Regulations (14 CFR) Sec. 414.35, this Notice publishes the criteria that were used to evaluate the safety approval application.

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by a report of a crack found in the fuselage during a fatigue test campaign. This proposed AD would require repetitive rototest inspections for cracking; corrective actions if necessary; and modification of the torsion box, which would terminate the repetitive inspections. We are proposing this AD to prevent cracking in the side box beam flange of the fuselage, which could affect the structural integrity of the airplane.

FMCSA announces the availability of and requests public comment on data and information about Importaciones y Distribuciones Latina America Gami SA de CV (IDLA), a new motor carrier that does not currently have a U.S. Department of Transportation (U.S.DOT) registration number. IDLA applied to participate in the Agency's long- haul pilot program to test and demonstrate the ability of Mexico- domiciled motor carriers to operate safely in the United States beyond the municipalities in the United States on the United States-Mexico international border or the commercial zones of such municipalities. This action is required by the ``U.S. Troop Readiness, Veterans' Care, Katrina Recovery, and Iraq Accountability Appropriations Act, 2007'' and all subsequent appropriations.

The Federal Motor Carrier Safety Administration (FMCSA), after consultation with representatives of the governors of the affected States, rescinds certain covered emergency exemptions. The exemptions originally took effect automatically upon declaration of an emergency by various governors or FMCSA, and were extended by FMCSA after consultation with representatives of the governors. The President signed the ``Home Heating Emergency Assistance Through Transportation Act of 2014'' (HHEATT Act, or ``the Act'') on March 21, 2014. The Act extends until May 31, 2014, all ``covered emergency exemptions'' created between February 5, 2014, and March 21, 2014, to provide regulatory relief to commercial motor vehicle operators directly supporting the delivery of propane and other home heating fuels. In accordance with the Act, FMCSA has consulted with representatives of each of the governors to determine whether emergency circumstances still exist and has determined that certain covered emergency exemptions created under the HHEATT Act are no longer necessary and should be rescinded.

We are superseding airworthiness directive (AD) 2007-19-09R1 for all Turbomeca S.A. Arriel 2B1 turboshaft engines that do not have modification TU157 incorporated. AD 2007-19-09R1 required replacement of the hydromechanical metering unit (HMU) with a serviceable HMU. This AD requires HMU replacement; reduction of the compliance interval; and inclusion of the power turbine C2 cycle consumption rate when determining compliance times. This AD was prompted by reports of ruptures on HMU constant delta pressure valves that have less than 2,000 hours in service. We are issuing this AD to prevent failure of the HMU, which could lead to damage to the engine, and damage to the aircraft.
