Department of Transportation February 18, 2009 – Federal Register Recent Federal Regulation Documents

As authorized by 46 U.S.C. 12121, the Secretary of Transportation, as represented by the Maritime Administration (MARAD), is authorized to grant waivers of the U.S.-build requirement of the coastwise laws under certain circumstances. A request for such a waiver has been received by MARAD. The vessel, and a brief description of the proposed service, is listed below. The complete application is given in DOT docket MARAD-2009-XXXX at https://www.regulations.gov. Interested parties may comment on the effect this action may have on U.S. vessel builders or businesses in the U.S. that use U.S.-flag vessels. If MARAD determines, in accordance with 46 U.S.C. 12121 and MARAD's regulations at 46 CFR Part 388 (68 FR 23084; April 30, 2003), that the issuance of the waiver will have an unduly adverse effect on a U.S.-vessel builder or a business that uses U.S.-flag vessels in that business, a waiver will not be granted. Comments should refer to the docket number of this notice and the vessel name in order for MARAD to properly consider the comments. Comments should also state the commenter's interest in the waiver application, and address the waiver criteria given in Sec. 388.4 of MARAD's regulations at 46 CFR Part 388.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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:

We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 747-400 and 747-400D series airplanes. This proposed AD would require repetitive inspections to detect cracks in the floor panel attachment fastener holes of the Section 41 upper deck floor beam upper chords, and related investigative and corrective actions if necessary. This proposed AD results from reports of cracks found in the Section 41 upper deck floor beam upper chords. We are proposing this AD to detect and correct cracks in these chords, which could become large and cause the floor beams to become severed and result in rapid decompression or reduced controllability of the airplane.

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:

This action revises Class E airspace at Galena, AK to provide adequate controlled airspace to contain aircraft executing Standard Instrument Approach Procedures (SIAPs). Two SIAPs are being amended for the Edward G. Pitka Airport at Galena, AK. This action revises existing Class E airspace upward from 700 feet (ft.) and 1,200 ft. above the surface at Edward G. Pitka Airport, Galena, AK.

We are adopting a new airworthiness directive (AD) for certain Learjet Model 55, 55B, and 55C airplanes. This AD requires inspecting the installation of the forward light assembly in the aft lavatory to determine the location of the terminal connector; inspecting for damage of the light assembly terminals, wires, and oxygen lines; inspecting to determine if the cable nipple is installed over the light assembly terminal; and doing corrective actions if necessary. This AD also requires installing a clamp to the forward side of the frame to maintain a positive distance between the light assembly and oxygen line. This AD results from a report of a cabin fire in the left-hand upper cabin fuselage above the aft cabin window at frame 23. We are issuing this AD to detect and correct improper installation of the lavatory light assembly, which could result in contact between the electrical terminals of the light assembly and an adjacent oxygen supply line, and consequent short circuit or fire hazard.

The FAA is adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 401, 401A, 401B, 402, 402A, and 402B airplanes. This AD requires an inspection of the auxiliary wing spar near the location where the main landing gear trunnion is mounted for cracks; immediate replacement if cracks of 0.5 inch or more are found; repetitive inspections with replacement at a later time as long as cracks of less than 0.5 inch are found; and a report to the FAA and Cessna if any cracks are found. This AD results from several reports of fatigue cracking on the affected airplanes in the auxiliary wing spar. We are issuing this AD to detect and correct such cracks, which, if not corrected, could result in failure of the wing auxiliary spar web and cause landing gear collapse during normal landing. This could lead to loss of control and passenger injury.

This action amends Class E airspace at Tulsa, OK. Additional controlled airspace is necessary to accommodate Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAP) at William R. Pogue Municipal Airport, Sand Springs, OK. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at William R. Pogue Municipal Airport.

This action removes Class E airspace at Rockport, TX. This airspace has been incorporated into the Corpus Christi, TX, Class E airspace area under a separate rulemaking action to ensure the safety of aircraft and efficient use of airspace.
