Department of Transportation March 30, 2010 – Federal Register Recent Federal Regulation Documents

On December 30, 2009, the Department of Transportation (DOT or Department) published a final rule that requires, among other things, that U.S. carriers adopt contingency plans for lengthy tarmac delays that include an assurance that a carrier will not permit an aircraft to remain on the tarmac for more than three hours in the case of domestic flights and for more than a set number of hours as determined by a carrier in the case of international flights without providing passengers an opportunity to deplane, with certain exceptions for safety, security or Air Traffic Control-related reasons. This rule becomes effective on April 29, 2010. Several airlines have requested an exemption from these requirements for operations at John F. Kennedy International Airport (JFK), for seven months in 2010 during which runway construction is expected to be under way at that airport and the rule will otherwise be effective, one airline has asked that operations at Newark Liberty International Airport (EWR) and LaGuardia Airport (LGA) be similarly exempted for the same time period, and another has requested that Philadelphia International Airport (PHL) be included in any relief granted by the Department. The Department is seeking comment on the exemption requests to assist it in deciding whether it should grant or deny these requests. The Department will publish a document in the Federal Register regarding its decision on the exemption requests after it has reviewed the comments submitted.

The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 222: Inmarsat Aeronautical Mobile Satellite (Route) Services.

Pursuant to a statutory mandate in the Cameron Gulbransen Kids Transportation Safety Act of 2007, NHTSA is placing a requirement in Federal Motor Vehicle Safety Standard No. 114 that certain motor vehicles with an automatic transmission that includes a ``park'' position manufactured for sale on or after September 1, 2010 be equipped with a brake transmission shift interlock (BTSI). This interlock must necessitate that the service brake pedal be depressed before the transmission can be shifted out of ``park,'' and must function in any starting system key position. The BTSI requirement adopted by this final rule is identical in substance to the Congressional requirement.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Investigation of an uncommanded in-flight shutdown (IFSD) revealed that a third stage turbine wheel rupture was not contained by the turbine casings. The released portion consisted of a turbine blade together with the rim piece immediately below the blade. The rim piece was bounded by two adjacent axial slots and a fatigue crack that had developed between the holes in which the slots terminate. The slots and holes, which are closed by riveted plugs, were introduced by modification AB 173 in order to improve the vibration characteristics of the turbine wheel. Modification AB 208 brings an improvement to modification AB 173 by changing only the riveting detail. SN 283 72 0805 provides instructions for re-boring the holes at overhaul or repair in order to improve their surface condition. A manufacturing process modification has been introduced to improve the surface condition of these holes in third stage turbine wheels. Wheels subject to the improved manufacturing process have S/Ns outside the range specified in Table 1. Although there is only one known event, and although it resulted only in an uncommanded IFSD, with no damage to the aircraft, the possibility exists that additional events may occur, potentially involving damage to the aircraft.

The FAA is correcting a final rule published on February 1, 2010. In that rule, the FAA amended its regulations for sport pilots

We propose to supersede Airworthiness Directive (AD) 2009-24- 13, which applies to certain Cessna Aircraft Company (Cessna) Model 525A airplanes. AD 2009-24-13 currently requires you to repetitively inspect the thrust attenuator paddle assemblies for loose and damaged fasteners and for cracks. AD 2009-24-13 also requires you to replace loose or damaged fasteners and replace cracked thrust attenuator paddles found during any inspection. Since we issued AD 2009-24-13, Cessna has developed new design thrust attenuator paddles and universal head rivets as terminating action for the repetitive inspections. Consequently, this proposed AD would retain the requirements of AD 2009-24-13 until replacement of both thrust attenuator paddles and the eight countersunk fasteners with new design thrust attenuator paddles and universal head rivets. We are proposing this AD to detect and correct loose and damaged fasteners and cracks in the thrust attenuator paddles, which could result in in-flight departure of the thrust attenuator paddles. This failure could lead to rudder and elevator damage and result in loss of control.

This notice contains a summary of a petition seeking relief from specified requirements of 14 CFR. The purpose of this notice is to improve the public's awareness of, and participation in, this aspect of FAA's regulatory activities. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of any petition or its final disposition.

This document establishes the test procedures to be used by tire manufacturers in a new consumer information program to generate comparative performance information to inform consumers about the effect of their choices among replacement passenger car tires on fuel efficiency, safety, and durability. When this program is fully established, this information will be provided to consumers at the point of sale and online. This information will encourage the purchase of better performing replacement tires.
