Airworthiness Directives; The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400F, 747SR, and 747SP Series Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747- 200F, 747-300, 747-400, 747-400F, 747SR, and 747SP series airplanes. This proposed AD would require reworking or replacing certain duct assemblies in the environmental control system (ECS). This proposed AD results from reports of duct assemblies in the ECS with burned Boeing Material Specification (BMS) 8-39 polyurethane foam insulation. This proposed AD also results from a report from the airplane manufacturer that airplanes were assembled with duct assemblies in the ECS wrapped with BMS 8-39 polyurethane foam insulation, a material of which the fire retardant properties deteriorate with age. We are proposing this AD to prevent a potential electrical arc from igniting the BMS 8-39 polyurethane foam insulation on the duct assemblies of the ECS, which could propagate a small fire and lead to a larger fire that might spread throughout the airplane through the ECS.
Agency Information Collection; Activity Under OMB Review; Omnibus Household Survey Program
In accordance with the requirements of section 3506(c)(2)(A) of the Paperwork Reduction Act of 1995, this notice announces that the Information Collection Request (ICR) described below is being forwarded to the Office of Management and Budget (OMB) for approval for an extension of a currently approved information collection related to the use of and satisfaction with the nation's transportation system. The ICR describes the nature of the information collection and its expected burden. The Federal Register notice with a 60-day comment period soliciting comments on the following collection of information was published on February 2, 2010 (75 FR 5370) and the comment period ended on April 5, 2010. The 60-day notice produced no comments.
Special Conditions: Modification to Boeing Model 737-600/-700/-700C/-800/-900 and -900ER Series Airplanes: Rechargeable Lithium Batteries and Rechargeable Lithium-Battery Systems
These special conditions are issued for the Boeing 737-600/- 700/-700C/-800/-900 and -900ER Series airplanes (hereafter referred to as ``Boeing 737NG''). These airplanes, as modified by the Boeing Company, will have a novel or unusual design feature associated with the installation of rechargeable lithium batteries and rechargeable lithium-battery systems. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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.
Supplemental Notice of Intent To Prepare an Environmental Assessment and Request for Public Scoping Comments for the Air Tour Management Plan Program at Mount Rainier National Park
The FAA, with National Park Service (NPS) as a cooperating agency, has initiated development of an Air Tour Management Plan (ATMP) for Mount Rainier National Park (MORA), pursuant to the National Parks Air Tour Management Act of 2000 (Pub. L. 106-181) and its implementing regulations (14 CFR Part 136, Subpart B, National Parks Air Tour Management). The objective of the ATMP is to develop acceptable and effective measures to mitigate or prevent the significant adverse impacts, if any, of commercial air tour operations upon the natural resources, cultural resources, and visitor experiences of a national park unit and any tribal lands within or abutting the park. It should be noted that the ATMP has no authorization over other non-air-tour operations such as military and general aviation operations. In compliance with the National Environmental Policy Act of 1969 (NEPA) and FAA Order 1050.1E, CHG 1, an Environmental Assessment is being prepared. This supplemental notice of intent extends the date by which scoping comments must be submitted (see DATES) because the original Federal Register notice published on April 2, 2010 (Vol. 75, No. 63, 16899-16900) referenced a link to the FAA Web site that had the wrong public scoping packet. The correct public scoping packet has now been posted.
Amendment of Class E Airspace; North Bend, OR
This action will modify Class D airspace at Southwest Oregon Regional Airport, North Bend, OR, to allow aircraft at Sunnyhill Airport to arrive and depart outside Class D airspace. This action is necessary for the safety and management of Instrument Flight Rules (IFR) aircraft utilizing both airports.
Amendment of Class E Airspace; Rifle, CO
This action will establish Class E airspace at Rifle, CO. Additional controlled airspace is necessary to accommodate aircraft executing new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) at Garfield County Regional Airport. This will improve the safety of Instrument Flight Rules (IFR) operations at the airport. This action also changes the airport name in the existing Class E airspace description.
