Department of Transportation December 16, 2005 – Federal Register Recent Federal Regulation Documents

This notice announces the issuance of Advisory Circular (AC) 23-24, Airworthiness Compliance Checklists for Common Part 23 Supplemental Type Certificate (STC) Projects. The AC standardizes compliance checklists for common Title 14 of the Code of Federal Regulations (14 CFR) part 23 STC projects. These checklists may be used to fulfill some of the requirements for a Certification Plan for STC projects. The standard compliance checklists show typical methods of compliance with the regulations and cross-references related guidance material. Checklists created using the information in the AC complement the guidance in the Guides for Certification of Part 23 Airplanes (ACs 23-8B, 23-16A, 23-17B, and 23-19) and other project-specific guidance. The checklists may contain complete certification requirements or may be used as a starting place when applying for an STC that may be beyond the scope of the checklists.

In accordance with the procedures governing the application for, and the processing of special permits from the Department of Transportation's Hazardous Material Regulations (49 CFR part 107, subpart B), notice is hereby given that the Office of Hazardous Materials Safety has received the application described herein. This notice is abbreviated to expedite docketing and public notice. Because the sections affected, modes of transportation, and the nature of application have been shown in earlier Federal Register publications, they are not repeated here. Request of modifications of special permits (e.g. to provide for additional hazardous materials, packaging design changes, additional mode of transportation, etc.) are described in footnotes to the application number. Application numbers with the suffix ``M'' demote a modification request. There applications have been separated from the new applications for special permits to facilitate processing.

This notice advises the public that the comment period for the Draft Supplemental Environmental Assessment (DSEA) for the proposed modification to the Four Corner-Post Plan at Las Vegas McCarran International Airport, Las Vegas, Nevada is extended.

The Federal Aviation Administration (FAA) is giving notice that 1.29 + / - acres (Parcel P-1R) of the airport property located at Southern Illinois Airport, Carbondale-Murphysboro, Illinois, will be released. This acreage is adjacent to the Airport Entrance Road and in close proximity to Airport Road and Fox Farm Road. It is in the southern part of Tract P-1, which is 11.024 acres. Tract P-1 was originally acquired in fee on August 20, 1975, with partial federal funding of Grant 7-17-00077-02. The proposed sale of will facilitate the construction of a centralized 911 emergency dispatch center, which will serve all of Jackson County. It will combine the current emergency dispatch functions of the cities of Carbondale and Murphysboro, Jackson County and Southern Illinois University. This center will position first responders and mutual aid providers near the airport for the needs of the airport. The land use of the property is currently agricultural, which provides minimal income to the airport. This one-time sale will generate income for airport improvement purposes and build a better rapport with the surrounding communities and their officials. The future use of this release will be required to comply with part 77 surfaces, and in conformity with FAA Deed Restrictions as required in Appendix 3 of PPM 5190.6. The Exhibit `A' Property Line Map (Exhibit 1) and the Airport Layout Plan (Exhibit 2) depicts the exchange. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires that property to be used for an aeronautical purpose.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. This AD requires replacing the aileron control override quadrant with a modified unit. This AD results from a report of the seizing of the input override mechanism bearings of the lateral central control actuator on affected airplanes. We are issuing this AD to prevent corrosion of the input override mechanism bearings of the lateral central control actuator, which, in the event of a subsequent jam in the pilot's aileron control system, could result in failure of the aileron override system and consequent reduced lateral controllability of the airplane.

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes. This AD requires repetitive detailed inspections of the forward lugs of the power control unit (PCU), yoke assembly, and forward attachment hardware of the left inboard, left outboard, right inboard, and right outboard flaperon PCUs; and other specified/corrective actions if necessary. For certain airplanes, this AD also requires other related concurrent actions. This AD results from reports indicating that operators have found worn, fretted, and fractured bolts that attach the yoke assembly to the flaperon PCU. We are issuing this AD to prevent damage and eventual fracture of the yoke assembly, pin assembly, and attachment bolts that connect the inboard and outboard PCUs to a flaperon, which could lead to the flaperon becoming unrestrained and consequently departing from the airplane. Loss of a flaperon could result in asymmetric lift and reduced roll control of an airplane. A departing flaperon could also cause damage to the horizontal and vertical stabilizers, which could result in loss of control of the airplane if damage is significant.
