Federal Aviation Administration July 12, 2005 – Federal Register Recent Federal Regulation Documents

Under the provisions of Title 49, U.S.C. Section 47153(d), notice is being given that the FAA is considering a request from the City of Monroe to waive the requirement that a 8.7 acre parcel of surplus property, located at the Monroe Regional Airport, be used for aeronautical purposes.

This document sets forth the Federal Aviation Administration's (FAA) policy concerning the shared responsibility between design approval holders (DAHs) and operators in achieving certain types of safety objectives. It also provides guidance on the use of DAH requirements to support these safety objectives. This policy statement is intended to further clarify when and how the FAA will use DAH requirements in the future to address certain airworthiness issues for transport airplanes.

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 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 notice announces the extension of the comment period for the notice of availability of and request for comments on a proposed advisory circular, Advisory Circular (AC) 23-13A, Fatigue, Fail-Safe, and Damage Tolerance Evaluation of Metallic Structure for Part 23 Airplanes. The FAA is extending the comment period to allow companies and individuals adequate time to complete their comments to the proposed AC.

This proposal would revise Class E airspace at Herlong, CA. Additional controlled airspace is necessary to contain Instrument Flight Rules (IFR) aircraft during airborne holding at Amedee Army Air Field (AAF) due to weather below landing minimums, traffic congestion, or other operational reasons. Holding airspace is designated at specific altitudes and lateral boundaries within controlled airspace to provide a safe environment above obstacles. This holding pattern is an integral part of the new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) at the Amedee AAF.

These special conditions are issued for Dassault Model Fan Jet Falcon, Fan Jet Falcon Series C, D, E, and F airplanes; Model Mystere- Falcon 200 airplanes; and Model Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 airplanes modified by Royal Air, Inc. These modified airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification is the installation of new air data display units (ADDU) and a new air data sensor, which perform critical functions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of high-intensity radiated fields (HIRF). 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.

An examination of controlled airspace for Topeka, Forbes Field, KS has revealed discrepancies in the airport reference point used in the legal description for the Class E airspace designated as a surface area. This action corrects that discrepancy by incorporating the current airport reference point in the Class E surface area for Topeka, Forbes Field, KS. This action also removes references to effective dates and times established in advance by a Notice to Airmen from the legal descriptions for Class D, Class E2 and Class E4 airspace. The effective dates and times are now continuously published in the Airport/Facility Directory.

The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 707-300B, -300C, and -400 series airplanes. This AD requires repetitive inspections to detect cracked or broken hinge fitting assemblies of the inboard leading edge slats, and corrective action if necessary. This AD also provides as an option a preventive modification, which defers the repetitive inspections. In addition, this AD provides an option of replacing all hinge fitting assemblies with new, improved parts, which terminates the repetitive inspection requirements. This AD is prompted by results of a review to identify and implement procedures to ensure the continued structural airworthiness of aging transport category airplanes. We are issuing this AD to detect and correct fatigue cracking of the hinge fitting assembly of the inboard leading edge slats, which could result in reduced structural integrity of the slat system. This condition could result in loss of the inboard leading edge slat and could cause the flightcrew to lose control of the airplane.
