Department of Transportation December 28, 2006 – Federal Register Recent Federal Regulation Documents

This advisory reminds operators of the need for vigilance in providing security at liquefied natural gas (LNG) facilities. PHMSA's pipeline safety regulations require operators to implement security measures that deter intruders at LNG terminals, facilities, and peak- shaving plants. This Advisory Bulletin reinforces the importance of effectively implementing and thoroughly testing security procedures and systems.

PHMSA has determined that the minimum random drug testing rate for covered employees will remain at 25 percent during calendar year 2007.

The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require inspecting the carbon-fiber reinforced plastic (CFRP) main landing gear (MLG) door to determine whether certain part numbers are installed. For airplanes having certain doors, this proposed AD would require inspecting the MLG outboard door for cracks, play, and loose sealant/bolts/nuts, and related investigative and corrective actions if necessary. This proposed AD would also require, for airplanes having certain doors, modifying the rod bracket attachment of the MLG outboard door. This proposed AD results from a report of a rod bracket of the MLG door detaching during flight. We are proposing this AD to detect and correct cracks in the rod bracket attachment bolts, which could result in the rod brackets detaching from the MLG door and blocking the proper functioning of the MLG.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 airplanes. This proposed AD would require installing spacer assemblies at the attachment points of the YZ-latches of the cargo loading system in the forward and aft cargo compartments, as applicable. This proposed AD results from tests that have shown that the attachment points of the YZ-latches of the cargo loading system fail under maximum loads. We are proposing this AD to prevent failure of the attachment points of the YZ-latches, which could result in unrestrained cargo causing damage to the fire protection system, hydraulic system, electrical wiring, or other equipment located in the forward and aft cargo compartments. This damage could adversely affect the continued safe flight of the airplane.

The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Bombardier Model CL-600-2B16 (CL-604) airplanes and Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. These models may be referred to by their marketing designations as RJ100, RJ200, RJ440, CRJ100, CRJ200, CRJ440, and CL-65. The original NPRM would have superseded an existing AD that currently requires revising the Emergency Procedures section of the airplane flight manual (AFM) to advise the flightcrew of additional procedures to follow in the event of stabilizer trim runaway. The existing AD also requires revising the Abnormal Procedures section of the AFM to advise the flightcrew of procedures to follow in the event of MACH TRIM, STAB TRIM, and horizontal stabilizer trim malfunctions. The existing AD also requires revising the Normal section of the AFM to require a review of the location of certain circuit breakers and a functional check of the stabilizer trim system. In addition, the existing AD requires installing circuit breaker identification collars and provides an optional terminating action for the requirements of the AD. The original NPRM proposed to require doing the previously optional terminating action (installation of a new horizontal stabilizer trim control unit). The original NPRM resulted from a determination that the terminating action is necessary to address reports of uncommanded horizontal stabilizer trim motion. This new action revises the original NPRM by not allowing the removal of applicable temporary revisions (TRs) to the Emergency and Abnormal Procedures sections of the AFM and by adding the proposed requirement for certain airplanes to re-insert the applicable TRs of the Emergency and Abnormal Procedures sections of the AFM under certain conditions. We are proposing this supplemental NPRM to prevent horizontal stabilizer trim uncommanded motion, which could result in reduced controllability of the airplane.

This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

This action amends Title 14 Code of Federal Regulations, part 71 (14 CFR 71) by modifying the Class E airspace area at Creston Municipal Airport, IA. An examination of controlled airspace for Creston, IA, revealed discrepancies in the legal description for the Class E airspace area. The intended effect of this rule is to provide controlled airspace of appropriate dimensions to protect aircraft executing Standard Instrument Approach Procedures (SIAP) to Creston Municipal Airport.
