Department of Transportation November 23, 2007 – Federal Register Recent Federal Regulation Documents

In response to Section 14(g) of the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act, the National Highway Traffic Safety Administration established a child restraint consumer information rating program. This program conducts a yearly assessment on the ease of using add-on child restraints and provides these ratings to the public. The program has been successful in encouraging child restraint manufacturers to improve their harness designs, labels, and manuals such that most now receive the top rating. However, some recent research, as well as a February 2007 public meeting held by the agency on the Lower Anchors and Tethers for Children (LATCH) system has indicated that some features that make child restraints easier to use are not being captured by the current program. Additionally, the agency wants to make sure that the program continues to provide useful information to the public. In an effort to further enhance the program and provide consumers with updated information we are proposing some new features and new rating criteria, and to adjust the scoring system. The agency anticipates that these program changes will result in more child restraints being used correctly by continuing to encourage manufacturers to install more features that help make the restraints easier to use.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 727 series airplanes. The existing AD currently requires repetitive inspections to detect cracks and loose brackets of the elevator rear spar, and corrective actions if necessary. The existing AD also provides for an optional terminating action for the repetitive inspections. This proposed AD would reduce the repetitive intervals of the inspections, mandate the previously optional terminating action for the repetitive inspections, and no longer allow stop-drilling. This proposed AD results from new reports of cracks, elongated fastener holes, and loose fittings of the elevator rear spar. We are proposing this AD to prevent cracking of the elevator rear spar at the tab hinge locations, which could cause excessive freeplay of the elevator control tab and possible tab flutter, and consequent loss of control of the airplane.

The FAA is superseding an existing airworthiness directive (AD) that applies to all Boeing Model 747-100B SUD, 747-300, 747-400, and 747-400D series airplanes; and Model 747-200B series airplanes having a stretched upper deck. The existing AD currently requires repetitively inspecting for cracking or discrepancies of the fasteners in the tension ties, shear webs, and frames at body stations 1120 through 1220, and performing related investigative and corrective actions if necessary. This new AD reduces the repetitive interval for certain inspections. This AD results from new reports of multiple severed adjacent tension ties, in addition to the previous reports of cracked and severed tension ties, broken fasteners, and cracks in the frame, shear web, and shear ties adjacent to tension ties for the upper deck. We are issuing this AD to detect and correct cracking of the tension ties, shear webs, and frames of the upper deck, which could result in rapid decompression and reduced structural integrity of the airplane.

Under the provisions of Title 49, U.S.C. Section 47153(c), notice is being given that the FAA is considering a request from the City of Starkville to waive the requirement that a 1.87 acre parcel of surplus property, located at the George M. Bryan Field Airport, be used for aeronautical purposes.
