Airworthiness Directives; Honeywell International Inc. TPE331 Series Turboprop, and TSE331-3U Model Turboshaft Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain Honeywell International Inc. TPE331 series turboprop, and TSE331-3U model turboshaft engines. This proposed AD would require implementing a new flight cycle counting method for first, second, and third-stage turbine rotors used in aircraft that make multiple takeoffs and landings without an engine shutdown, and removing turbine rotors from service that have reached or exceeded their cycle life limits. This new flight cycle counting method would require determining total equivalent cycles accrued. This proposed AD results from several reports of uncontained turbine rotor separation on engines used in special-use operations. We are proposing this AD to prevent uncontained failure of the turbine rotor due to low-cycle-fatigue (LCF), and damage to the aircraft.
Commercial Driver Instruction Permits; Withdrawal
FMCSA withdraws its notice of proposed rulemaking (NPRM) on additional minimum Federal standards for State-issued learner's permits that allow drivers to be trained in the operation of commercial motor vehicles (CMVs). The NPRM requesting comments was published on August 22, 1990, at 55 FR 34478. The comment period was extended to November 30, 1990 (55 FR 42741, October 23, 1990). FMCSA determined that the issues addressed in the NPRM and the public comments on these issues do not reflect many initiatives and activities that occurred after publication of the NPRM. Therefore, the 1990 NPRM is obsolete and it is in the public interest to withdraw it.

The ICRs describes the nature of the information collections and their expected burdens. The Federal Register notice with a 60-day comment period soliciting comments on the following collections of information was published on December 14, 2005 (70 FR 74103).
Houston, TX Requirements on Storage of Hazardous Materials During Transportation
A. Federal hazardous material transportation law preempts the following requirements in the Houston Fire Code as applied by the Houston Fire Department to the storage of hazardous materials during transportation at George Bush Intercontinental Airport, because (a) the designation, description, and classification of hazardous materials in the Fire Code is not substantively the same as in the HMR; (b) these requirements are not substantively the same as requirements in the HMR regarding the use of shipping documents to provide emergency response information in the event of an incident during the transportation of hazardous material; and (c) these requirements require advance notification of the transportation of hazardous materials which creates an obstacle to accomplishing and carrying out the purposes and goals of Federal hazardous material transportation law and the HMR: 1. Sections 105.8.h.1 and 8001.3.1, which require a permit to store, transport on site, dispense, use or handle hazardous materials in excess of certain ``exempt'' amounts listed in Table 105-C of the Fire Code. 2. Sections 105.8.f.3 and 7901.3.1, which require a permit to store, handle, transport, dispense, or use flammable or combustible liquids in excess of the amounts specified in Sec. 105.8.f.3. 3. Sections 8001.3.2 and 8001.3.3, which specify the Houston Fire Chief may require an applicant for a permit to provide a hazardous materials management plan and a hazardous materials inventory statement in accordance with the provisions of Appendix II-E of the Fire Code. B. Federal hazardous material transportation law preempts the separation requirements in sections 7902.1.6 and 8001.11.8 of the Houston Fire Code as applied by the Houston Fire Department to the storage of hazardous materials during transportation at George Bush Intercontinental Airport, because these requirements are not substantively the same as the segregation requirements in 49 CFR 175.78. C. There is insufficient information to find Federal hazardous material transportation law preempts the secondary containment requirements in sections 7901.8 and 8003.1.3.3 in the Houston Fire Code as enforced and applied by the Houston Fire Department to the storage of hazardous materials during transportation at George Bush Intercontinental Airport, including the construction and capacity requirements for storage cabinets for secondary containment in sections 7902.5.9 and 8001.10.6, because the application and comments do not show (a) it is impossible to comply with both these requirements and the Federal hazardous material transportation law, the regulations issued under that law, or a hazardous materials transportation security regulation or directive issued by the Secretary of Homeland Security (DHS), or (b) these requirements, as enforced and applied, are likely to cause diversions or delays in the transportation of hazardous materials. If the applicant wishes to provide further information regarding the secondary containment requirements in the Houston Fire Code, it may submit a new application.
Federal Motor Vehicle Safety Standards; Rear Impact Guards and Rear Impact Protection
To address the problem of rear underride crashes, Federal safety standards require heavy trailers and semitrailers to be equipped with underride guards. Compliance with these requirements is not practicable for vehicles featuring work-performing equipment mounted in the area where an underride guard would normally be located. These trailers and semitrailers are designated as ``special purpose vehicles'' and are excluded from the standard. On November 5, 2004, we published a final rule amending the definition of ``special purpose vehicles'' in order to clarify the exclusion by specifying the dimensions of the area where the work-performing equipment must reside or pass through in order for the exclusion to apply. On December 14, 2004, we were petitioned by the National Truck Equipment Association to reconsider the final rule because the amendment has had an unintended effect of narrowing the exclusion applicable to ``special purpose vehicles.'' In response to that petition for reconsideration, this document further amends the definition of a ``special purpose vehicle'' to exclude a specific group of vehicles that cannot comply with the underride guard requirements in a practicable manner.
Accommodations for Individuals Who Are Deaf, Hard of Hearing, or Deaf-Blind
This notice of proposed rulemaking (NPRM) proposes to amend a previously published proposed rule that implements the Air Carrier Access Act (ACAA), to provide for additional accommodations for air travelers who are deaf, hard of hearing or deaf-blind. This proposed rule applies to U.S. air carriers, to foreign air carriers for their flights into and out of the United States, to airport facilities located in the U.S. that are owned, controlled or leased by carriers, and to aircraft that serve a U.S. airport. It proposes to require U.S. and certain foreign air carriers to provide prompt access for individuals who identify themselves as requiring hearing or visual assistance to the same information provided to other passengers in the terminal and on the aircraft; caption safety and informational videos, DVDs and other audio-visual displays shown on new and existing aircraft; caption entertainment videos, DVDs and other audio-visual displays on new aircraft; ensure that individuals calling a carrier's TTY line for information or reservations receive equal response time and level of service (including queuing or other automated response service) as that provided to individuals calling a non-TTY information or reservation line; enable captioning on televisions and audio-visual equipment located in those portions of U.S. airports that are owned, leased or controlled by carriers and open to public access to the extent that such equipment has captioning capability on the effective date of this rule; replace non-caption capable televisions and audio- visual displays with captioning capable technology in the normal course of operations or when relevant airport facilities undergo substantial renovation or expansion; and train carrier personnel to proficiency on recognizing requests for communication accommodations and communicating with individuals who have visual or hearing impairments.
Modification of Class E Airspace; Beatrice, NE
This document confirms the effective date of the direct final rule which revises Class E airspace at Beatrice, NE.
Notice of Opportunity for Public Comment on Surplus Property Release at Craig Field Airport, Selma, AL
Under the provisions of Title 49, U.S.C. Section 47153(c), notice is being given that the FAA is considering a request from the Craig Field Airport and Industrial Authority to waive the requirement that a 0.93-acre parcel of surplus property, located at the Craig Field Airport, be used for aeronautical purposes.
Airworthiness Directives; AvCraft Dornier Model 328-100 Airplanes
The FAA is revising an existing airworthiness directive (AD) that applies to all AvCraft Dornier Model 328-100 airplanes. That AD currently requires revising the airplane flight manual (AFM) to provide the flightcrew with additional information regarding procedures to ensure complete pressurization of the hydraulic lines for the flaps. The existing AD also requires, for certain airplanes, modifying of the flap actuators of the flight controls. We issued that AD to prevent an uncommanded retraction of the flaps during takeoff, which could result in an aborted takeoff and consequent potential for runway overrun. This new AD allows the removal of the AFM revisions after modifying the flap actuators of the flight controls. This AD results from the determination that the AFM revisions are not necessary after modifying the flap actuators of the flight controls. We are issuing this AD to prevent an uncommanded retraction of the flaps during takeoff, which could result in an aborted takeoff and consequent potential for runway overrun.
Airworthiness Directives; General Electric Company CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for General Electric Company (GE) CF34-3A1 and -3B1 series turbofan engines. That AD requires initial and repetitive visual inspections and eddy current inspections (ECIs) of certain stage 5 low pressure turbine (LPT) disks and stage 6 LPT disks, installed in GE CF34-3A1 and -3B1 series turbofan engines. Those engines are installed in certain Bombardier Canadair Regional Jet (RJ) airplanes. This AD requires the same initial and repetitive visual inspections and ECIs, but adds SNs to the affected disk population for RJ airplanes. This AD also adds GE CF34-1 and -3 series turbofan engines with certain stage 5 and stage 6 LPT disks, to the applicability section. Those engines are installed in certain Bombardier Canadair Business Jet (BJ) airplanes. Also, this AD requires eventual replacement of the affected disks as terminating action to the repetitive inspections. This AD results from the discovery of an additional population of suspect stage 5 LPT disks and stage 6 LPT disks that could fail due to low-cycle fatigue cracking that may start at the site of an electrical arc-out on the disk. We are issuing this AD to prevent low-cycle-fatigue (LCF) failure of stage 5 LPT disks and stage 6 LPT disks, which could lead to uncontained engine failure.
