Department of Transportation December 13, 2006 – Federal Register Recent Federal Regulation Documents

NHTSA published a final rule in December 2004 that amended the Federal motor vehicle safety standard on brake hoses, and announced an effective date of December 20, 2006. The agency has received several petitions for reconsideration of the rule and a petition to delay the effective date of the final rule. To allow for more time to respond to petitions for reconsideration, and to give industry more time to meet new requirements, this document delays the effective date of the final rule for one year, to December 20, 2007. This decision was made after NHTSA published a notice of proposed rulemaking on November 15, 2006, soliciting public comment on whether the effective date should be extended. All commenters wrote in support of extending the effective date.

These special conditions are issued for the Airbus A380-800 airplane, which has novel and unusual design features, such as a full- length, double deck passenger cabin and electrical equipment bays distributed throughout the airplane. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards regarding fire protection. 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. Additional special conditions will be issued for other novel or unusual design features of the Airbus Model A380-800 airplane.

The FAA proposes to supersede an existing airworthiness directive (AD) for certain MT-Propeller Entwicklung GmbH variable pitch and fixed pitch propellers manufactured before 1995 which had not been overhauled since April 1994. That AD currently requires overhauling the propeller blades and performing initial and repetitive visual inspections of affected propeller blades. That AD also requires removing all propeller blades from service with damaged erosion sheath bonding or loose erosion sheaths and installing any missing or damaged polyurethane protective strips. This proposed AD would require the same actions. This proposed AD results from the need to clarify the population of affected propellers previously listed in AD 2006-05-05. We are proposing this AD to prevent erosion sheath separation leading to damage of the airplane.

FMCSA announces receipt of applications from 66 individuals for exemptions from the prohibition against persons with insulin- treated diabetes mellitus (ITDM) operating commercial motor vehicles (CMVs) in interstate commerce. If granted, the exemptions would enable these individuals with ITDM to operate commercial motor vehicles in interstate commerce.

This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6-80C2 series turbofan engines. This proposed AD would require replacing certain installed part number (P/N) and serial number (SN) cast titanium weld-repaired forward engine mount platforms and cast titanium forward mount yokes, with a forged titanium or a non-welded cast titanium part. This proposed AD results from the discovery of cracks, in a weld-repaired area on a forward engine mount platform and a forward engine mount yoke, found during a fluorescent penetrant inspection (FPI). These parts were weld-repaired during manufacture. We are proposing this AD to prevent cracks in the forward engine mount platform and forward engine mount yoke that could result in possible separation of the engine from the airplane.

In accordance with the requirements of 49 U.S.C. 5117(c), PHMSA is publishing the following list of special permit applications that have been in process for 180 days or more. The reason(s) for delay and the expected completion date for action on each application is provided in association with each identified application.
