Department of Transportation March 20, 2007 – Federal Register Recent Federal Regulation Documents

Pursuant to FAA's rulemaking provisions governing the application, processing, and disposition of petitions for exemption part 11 of Title 14, Code of Federal Regulations (14 CFR), this notice contains a summary of certain petitions 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 the 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.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777 airplanes. This proposed AD would require repetitive measurements of the freeplay of certain joints of the trailing edge flap supports; repetitive lubrication of the support joints; and related investigative and corrective actions if necessary. The proposed AD also provides for modifying certain components of the trailing edge flap supports, which would extend the intervals for the repetitive measurements, and revising the maintenance practices of the maintenance planning data document. This proposed AD results from reports of excessive wear of the pins, bushings, and bearings, and corrosion at the joints of the outboard trailing edge flap supports. We are proposing this AD to prevent wear and corrosion at the flap support joints, which could result in loss of the trailing edge flap and possible loss of control of the airplane.

The FHWA is issuing this revised notice to advise the public that an environmental impact statement (EIS) is being prepared for the proposed U.S. Highway 181 Harbor Bridge replacement/State Highway (SH) 286 (Crosstown Expressway) improvement highway project in Nueces County, Texas, and that the project and study limits described in the May 20, 2005, Notice of Intent (NOI) have been expanded.
