Railroad Grade Crossing Safety; Withdrawal
FMCSA withdraws a July 30, 1998, Notice of Proposed Rulemaking (NPRM) that would have prohibited the driver of a commercial motor vehicle (CMV) from driving onto a highway-railroad grade crossing without sufficient space to drive completely through the crossing without stopping. The NPRM was issued in response to section 112 of the Hazardous Materials Transportation Authorization Act of 1994. After careful analysis and review of the comments, FMCSA has concluded that the NPRM gave a misleading impression of the statutory mandate and the cost and complexity of complying with an implementing regulation. FMCSA is therefore withdrawing the 1998 NPRM in order to eliminate the confusion associated with this rulemaking. The agency, however, will issue a simpler and more clearly written new NPRM addressing the requirements of section 112.
Federal Motor Vehicle Safety Standards; Occupant Crash Protection
This document denies a petition for rulemaking submitted by Mr. James E. Hofferberth asking the agency to take a variety of steps related to incorporating dummies representing three-year-old, six-year- old and ten-year-old children and 95th percentile adult males into the agency's frontal crash test programs.
Airworthiness Directives; Mitsubishi Heavy Industries MU-2B Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Mitsubishi Heavy Industries (MHI) MU-2B series airplanes. This proposed AD would require you to do flight checks of the rigging of the engine and propeller systems. This proposed AD results from a recent safety evaluation that used a data-driven approach to evaluate the design, operation, and maintenance of the MU-2B series airplanes in order to determine their safety and define what steps, if any, are necessary for their safe operation. Part of that evaluation was the identification of unsafe conditions that exist or could develop on the affected type design airplanes. We are issuing this proposed AD to detect and correct improper adjustment of the flight idle fuel flow setting. This condition, if uncorrected, could result in degraded performance and poor handling qualities with consequent loss of control of the airplane in certain situations.
Airworthiness Directives; Mitsubishi Heavy Industries MU-2B Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Mitsubishi Heavy Industries (MHI) MU-2B series airplanes. This proposed AD would require you to incorporate power assurance charts into the Limitations Section of the Airplane Flight Manual (AFM), inspect the engine torque indication system, and recalibrate the torque pressure transducers as required. This proposed AD results from a recent safety evaluation that used a data-driven approach to analyze the design, operation, and maintenance of the MU-2B series airplanes in order to determine their safety and define what steps, if any, are necessary for their safe operation. Part of that evaluation was the identification of unsafe conditions that exist or could develop on the affected type design airplanes. We are issuing this proposed AD to detect and correct torque transducers that are out of calibration. The above issue, if uncorrected, could result in degraded performance and poor handling qualities with consequent loss of control of the airplane in certain situations.
National Environmental Policy Act (NEPA) Implementing Instructions for Airport Actions
The Federal Aviation Administration's Office of Airports (ARP) has updated and revised its instructions for implementing the National Environmental Policy Act (NEPA) for airport actions. ARP is replacing Order 5050.4A, Airport Environmental Handbook with the updated and revised instructions in Order 5050.4B, National Environmental Policy Act (NEPA) Implementing Instructions for Airport Actions. This Notice announces the availability of Order 5050.4B and its Preamble. The documents are available at ARP's Web site https://www.faa.gov/ airportsairtraffic/ airports. Although APR is presenting the Preamble on its Web site, it is not including the text of that document in this Notice. ARP expects to publish the text in the Federal Register within the next 10 days. This delay is due to publication procedures associated with the extensively detailed Preamble.
