Department of Transportation August 18, 2005 – Federal Register Recent Federal Regulation Documents

The Federal Aviation Administration (FAA) announces the availability of final policy on a component method for demonstrating that a seat with a replacement bottom cushion complies with Sec. 25.562(c)(2). This policy addresses non-flotation monolithic (single layer) cushions.

In accordance with the procedures governing the application for, and the processing of, exemptions 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 application described herein. Each mode of transportation for which a particular exemption is requested is indicated by a number in the ``Nature of Application'' portion of the table below as follows: 1Motor vehicle, 2Rail freight, 3Cargo vessel, 4Cargo aircraft only, 5Passenger-carrying aircraft.

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain McDonnell Douglas Model DC-9-10, -20, -30, -40 and -50 series airplanes, and Model DC-9-81 (MD-81), and DC-9-82 (MD-82) airplanes. That AD currently requires installing a water drain system for the slant pressure panels in the left and right wheel wells of the main landing gear (MLG). This proposed AD would also require inspecting the seal assemblies of the overwing emergency exit doors for defects and constant gap; replacing defective door seals; performing repetitive operational checks of the water drain system auto drain valve and corrective actions if necessary; and, for certain airplanes, modifying the insulation blankets on the slant pressure panels in the left and right MLG wheel wells. This proposed AD is prompted by reports of water runoff from the slant pressure panels in the left and right MLG wheel wells, which subsequently froze on the lateral control mixer and control cable assemblies. We are proposing this AD to prevent ice from forming on the lateral control mixer and control cable assemblies, which could reduce controllability of the airplane.

This document proposes to amend Part 567 to require that, in addition to the vehicle identification number, additional information be recorded on the certification label of each bus manufactured in two or more stages. The information would identify the bus body manufacturer and various vehicle attributes. This document also proposes to add a new Part 584 to require manufacturers of bus bodies for buses manufactured in two or more stages to obtain a manufacturer's identifier and to provide information to NHTSA about the bus bodies manufactured.
