Department of Transportation February 23, 2011 – Federal Register Recent Federal Regulation Documents

We propose to adopt a new airworthiness directive (AD) for the products listed above, except for those that are currently affected by similar action through any of five ADs applicable to Boeing products. This proposed AD would require an inspection/records check to determine the manufacturer and part number of the oxygen mask assemblies installed, an inspection to determine the manufacturing date and modification status if certain oxygen mask assemblies are installed, and corrective action for certain oxygen mask assemblies. This proposed AD was prompted by a report that several oxygen mask assemblies with broken in-line flow indicators were found following a mask deployment. We are proposing this AD to prevent the in-line flow indicators of the oxygen mask assembly from fracturing and separating, which could inhibit oxygen flow to the masks. This condition could consequently result in occupants developing hypoxia following a depressurization event.

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:

This action corrects errors in the legal description of a final rule published in the Federal Register on December 20, 2010 that amends Class E airspace at Henderson, KY.

This action amends Class E surface airspace and airspace 700 feet above the surface, and removes Class E airspace designated as an extension to Class D airspace at Easton, MD. The Easton Non-Directional Beacon (NDB) has been decommissioned and new Standard Instrument Approach Procedures (SIAPs) have been developed for Easton Airport/ Newnam Field. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.

By Federal Register notice (See 75 FR 68023; November 4, 2010) the National Park Service (NPS) and the Federal Aviation Administration (FAA) invited interested persons to apply to fill two vacant positions on the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). These notices invited interested persons to apply to fill two vacancies representing environmental concerns due to the incumbent member's completion of their three-year term appointments on May 30, 2011. This notice informs the public of the persons selected to fill the vacancies on the NPOAG ARC.

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 applications 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. Requests for modification 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'' denote a modification request. These applications have been separated from the new application for special permits to facilitate processing.
