In accordance with the Paperwork Reduction Act of 1995, FMCSA announces its plan to submit the Information Collection Request (ICR) described below to the Office of Management and Budget (OMB) for review and approval, and invites public comment. The FMCSA requests approval to revise an ICR entitled, ``Training Certification for Entry-Level Commercial Motor Vehicle Operators,'' that relates to the training requirements for drivers applying for a commercial drivers license.

This document responds to a petition for reconsideration of our 2003 final rule establishing a braking-in-a-curve performance requirement for single unit trucks and buses. The braking-in-a-curve requirement has applied to air-braked truck tractors since 1997 and we determined that the requirement should also apply to single-unit trucks and buses. The requirement ensures that a vehicle's antilock brake system (ABS) maintains adequate stability and control during a hard stop on a curved, slippery road surface. A petition for reconsideration was received from the National Truck Equipment Association (NTEA), which seeks to exclude vehicles built in two or more stages and altered vehicles from the braking-in-a-curve requirement if such vehicles are manufactured or altered by a final stage manufacturer or alterer that builds no more than 250 affected vehicles per year. The agency is denying the petitioner's request for the reasons discussed in this document.

The FAA is superseding an existing airworthiness directive (AD), which applies to certain transport category airplanes identified above. That AD currently requires modification of the reinforced flight deck door and other actions related to the reinforced flight deck door. Those other actions include modifying the door, inspecting and modifying wiring in the area, and revising the maintenance program to require more frequent testing of the decompression panels of the flight deck door. This new AD continues to require the existing requirements. This new AD adds airplanes to the existing requirement of a one-time inspection for chafing of wire bundles in the area of the flight deck door and corrective actions if necessary. This proposed AD also removes certain airplanes from the applicability. This AD results from a report of smoke and fumes in the cockpit of a Model 737-300 series airplane. We are issuing this AD to prevent inadvertent release of the decompression latch and consequent opening of the decompression panel in the flight deck door, or penetration of the flight deck door by smoke, any of which could result in injury to the airplane flightcrew. We are also proposing this AD to detect and correct wire chafing, which could result in arcing, fire, and/or reduced controllability of the airplane.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A300-600 series airplanes. This AD requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors caused by latent failures, alterations, repairs, or maintenance actions, could result in fuel tank explosions and consequent loss of the airplane.
