Federal Aviation Administration October 5, 2010 – Federal Register Recent Federal Regulation Documents

In anticipation of Congress enacting a reauthorization of the Airport Improvement Program (AIP) the FAA is publishing this annual notice. This notice announces the criteria, application procedures, and schedule to be applied by the Secretary of Transportation in designating or redesignating, and funding capital development annually for up to 15 current (joint-use) or former military airports seeking designation or redesignation to participate in the MAP. While FAA currently has continuing authority to designate or redesignate airports, FAA does not have authority to issue grants for fiscal year 2011 MAP, and will not have authority until Congress enacts legislation enabling FAA to issue grants for fiscal year 2011. The MAP allows the Secretary to designate current (joint-use) or former military airports to receive grants from the Airport Improvement Program (AIP). The Secretary is authorized to designate an airport (other than an airport designated before August 24, 1994) only if: (1) The airport is a former military installation closed or realigned under the Title 10 U.S.C. Sec. 2687 (announcement of closures of large Department of Defense installations after September 30, 1977), or under Section 201 or 2905 of the Defense Authorization Amendments and Base Closure and Realignment Acts; or (2) The airport is a military installation with both military and civil aircraft operations. The Secretary shall consider for designation only those current or former military airports, at least partly converted to civilian airports as part of the national air transportation system, that will reduce delays at airports with more than 20,000 hours of annual delays in commercial passenger aircraft takeoffs and landings, or will enhance airport and air traffic control system capacity in metropolitan areas, or reduce current and projected flight delays (49 U.S.C. 47118(c)).

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires incorporating changes to the electronic flight information system and the airplane flight manuals. This AD was prompted by reports of uncommanded changes to the communications radio frequency, altitude preselect, and/or transponder codes. We are issuing this AD to correct faulty integration of hardware and software, which could result in unannunciated, uncommanded changes in communications radio frequency, transponder codes, and altitude preselect settings. These uncommanded changes could result in loss of communication with air traffic control due to improper communications frequency, autopilot level off at the incorrect altitude, or air traffic control loss of proper tracking of the aircraft.

We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

The FAA is superseding an existing airworthiness directive (AD), which applies to all Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747- 400F, and 747SR series airplanes. That AD currently requires repetitive inspections to find cracking of the web, strap, inner chords, and inner chord angle of the forward edge frame of the number 5 main entry door cutouts, and repair, if necessary. This new AD requires expanding the inspection areas to include the frame segment between stringers 16 and 23. This AD reinstates the repetitive inspections specified above for certain airplanes. This AD also requires repetitive inspections for cracking of repairs. This AD results from additional reports of cracks that have been found in the strap and inner chord of the forward edge frame of the number 5 main entry door cutouts, between stringers 16 and 23. We are issuing this AD to detect and correct such cracks. This condition, if not corrected, could cause damage to the adjacent body structure, which could result in depressurization of the airplane in flight.
