Modification of Class E Airspace; Columbus, NE
This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR 71) by revising Class E airspace areas at Columbus, NE. A review of the Class E airspace surface area and the Class E airspace area extending upward from 700 feet above ground level (AGL) at Columbus, NE reveals neither area complies with criteria for extensions nor reflects the current Airport reference point (ARP) for the Columbus Municipal Airport. Also, the legal descriptions of both areas are not in proper format. These airspace areas and their legal descriptions are modified to conform to the criteria in FAA Orders.
Proposed Advisory Circular 23-13A, Fatigue, Fail-Safe, and Damage Tolerance Evaluation of Metallic Structure for Part 23 Airplanes
This notice announces the availability of and requests 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 AC provides information and guidance on acceptable means, but not the only means of compliance with Title 14 of the Code of Federal Regulations (14 CFR) part 23, applicable to fatigue, fail-safe, and damage tolerance evaluations of metallic structure in normal, utility, aerobatic, and commuter category airplanes. The proposed AC is a significant revision to the existing AC 23-13, incorporating a reader friendly question and answer format, updated guidance based on recent policy documents, and updated flight load spectra. The proposed AC also provides information on approval of continued operational flight with known cracks in the structure of small airplanes. Finally, it consolidates existing policy documents, and certain technical reports, into a single document. This notice is necessary to give all interested people an opportunity to present their views on the proposed AC.
Public Notice for Waiver of Aeronautical Land-Use Assurance Kalamazoo/Battle Creek International Airport Kalamazoo, MI
The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport from aeronautical use to non-aeronautical use and to authorize the sale of the airport property. The proposal consists of 2 parcels of land totaling approximately 6.13 acres. Current use and present condition is as an overflow parking area for car rental vehicles on the southern portion of subject parcels. The northern portion of subject parcels is vacant, unimproved land. The land was not acquired with federal funds. There are no impacts to the airport by allowing the airport to dispose of the property. The proposal concerns selling the land to a corporation that will construct a commercial office building on the site. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the disposal of the airport property will be in accordance FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. 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 the property to be used for an aeronautical purpose.
Railroad Safety Advisory Committee; Notice of Meeting
FRA announces the next meeting of the RSAC, a Federal Advisory Committee that develops railroad safety regulations through a consensus process. The RSAC briefing topics may include a State of Safety Report; recent safety advisories; the Rail Integrity Task Force; implementation of the final rule on Performance Standards for Processor-Based Signal and Train Control Systems; and an update on other regulatory activity. Status reports will be given on the Roadway Worker Working Group, and other active working groups. The Event Recorder Working Group will report recommendations for a final rule, which the Committee will be asked to vote on by mail ballot following the meeting. The Committee will be asked to vote on (1) the Passenger Safety Working Group Emergency Preparedness recommendations for a proposed amendments to passenger safety regulations and (2) the Cab Working Conditions Occupational Noise Exposure recommendations for final rule. The Committee may be asked to adopt a task on revision of FRA rules governing railroad operating rules and practices.
Airworthiness Directives; Boeing Model 747 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD) that applies to all Boeing Model 747 series airplanes. The existing AD currently requires repetitive inspections for cracking of the top and side panel webs and panel stiffeners of the nose wheel well (NWW), and corrective actions if necessary. This new AD expands the area of inspection, adds a new ``secondary'' inspection if certain cracking is found, and reduces the intervals for the repetitive inspections. This AD is prompted by a report of an in-flight decompression of a Model 747-100 series airplane that had accumulated 27,241 total flight cycles. We are issuing this AD to detect and correct fatigue cracks in the top and side panel webs and stiffeners of the NWW, which could compromise the structural integrity of the NWW and could lead to the rapid decompression of the airplane.
Airworthiness Directives; Cessna Model 750 Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Cessna Model 750 airplanes. The AD requires repetitive inspections for clearance and chafing of an auxiliary power unit (APU) fuel tube assembly in the tail cone area of the airplane, and corrective actions if necessary. For certain airplanes, this AD also requires replacing the APU fuel line. This AD is prompted by reports of chafed APU fuel tubes leaking into the tail cone area due to interference between the fuel tube assembly and elevator flight control cables, hydraulic lines, and high-temperature bleed air couplings. We are issuing this AD to detect and correct this interference, which could result in chafing, fuel leaking into an area where ignition sources are present, and possible fire in an area without fire detection or extinguishing provisions.
Airworthiness Directives; BAE Systems (Operations) Limited Model Avro 146-RJ Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model Avro 146-RJ series airplanes. This AD requires an inspection of the Thales Avionics distance bearing indicator (DBI) to determine part number (P/N) and serial number (S/N), and replacement of the affected DBI with a new or modified DBI. This AD is prompted by a report of defective electrical insulators in DBIs. We are issuing this AD to prevent a short circuit in the DBI due to defective electrical insulation, which could potentially cause a loss of primary navigation instruments (such as airspeed indicator, altimeter, and global positioning system (GPS) information).
Airworthiness Directives; Boeing Model 707 Airplanes and Model 720 and 720B Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 707 airplanes and Model 720 and 720B series airplanes. That AD currently requires a preventive modification of the front spar fitting on the outboard engine nacelle. This new AD removes the requirement to do this preventive modification, and requires repetitive inspections for cracking of the front spar fitting of the inboard and outboard nacelle struts, and replacement of any cracked fitting with a new fitting. This AD also applies to more airplanes. This AD is prompted by a report indicating that a crack was found in a front spar fitting that had been replaced as part of the modification required by the existing AD. We are issuing this AD to detect and correct this cracking, which could result in reduced structural integrity of the engine nacelle, and consequent separation of an engine from the airplane.
Airworthiness Directives; LET a.s. Model Blanik L-13 AC Sailplanes
The FAA adopts a new airworthiness directive (AD) for all LET a.s. (formerly LET n.p.) (LET) Model Blanik L-13 AC sailplanes. This AD requires you to replace the original control bridge with the new strengthened control column mounting bridge. This AD is the result of a report of one case of cracks in the attachment of control levers on the control bridge. We are issuing this AD to correct cracks in the bedding of the front and rear control levers, which could result in failure of the control bridge for the sailplane. This failure could lead to loss of sailplane control.
