Department of Transportation December 14, 2007 – Federal Register Recent Federal Regulation Documents

This notice proposes revisions to Model Specifications for Screening Devices to Measure Alcohol in Bodily Fluids (Model Specifications) published in the Federal Register on August 2, 1994 (59 FR 39382). These devices test for the presence of alcohol using breath or bodily fluids such as saliva. The Model Specifications support State laws that target youthful offenders (i.e., ``zero tolerance'' laws) and the Department of Transportation's regulations on Alcohol Misuse Prevention, and encourage industry efforts to develop new technologies (e.g., non-breath devices) that measure alcohol content from bodily fluids. This notice proposes to remove testing of Interpretive Screening Devices (ISDs) and use of the Breath Alcohol Sample Simulator (BASS) device from the Model Specifications. The ISDs do not provide an unambiguous test result, as test results for ISDs are subjective and require interpretation by a test administrator or technician. Because the agency has determined the BASS device is not necessary for inclusion in the Model Specifications, this notice proposes to remove all references to the BASS device. Additionally, in order to ensure product integrity, this notice proposes guidelines for retesting devices when manufacturers contemplate changes, revisions, or upgrades to alcohol screening devices on the Conforming Products List (CPL). The proposed revisions to these Model Specifications would not affect devices currently listed on the CPL.

We are revising an earlier proposed airworthiness directive (AD) that applies to certain Air Tractor, Inc. (Air Tractor) AT-400, AT-500, AT-600, and AT-800 series airplanes. The earlier NPRM proposed to supersede Airworthiness Directive (AD) 2007-13-17, which applies to certain Air Tractor Models AT-602, AT-802, and AT-802A airplanes. AD 2007-13-17 currently requires you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. The earlier NPRM proposed to retain the inspection actions of AD 2007-13-17 for Models AT-602, AT-802, and AT-802A airplanes, including the compliance times and effective dates; establish new inspection actions for the AT-400 and AT-500 series airplanes; incorporate a mandatory terminating action for all airplanes; and terminate the reporting requirement of AD 2007-13-17. The earlier NPRM resulted from a Model AT-502B with a crack located where the lower engine mount tube is welded to the engine mount ring, and the manufacturer developing gussets that, when installed according to their service letter, terminate the repetitive inspection requirement. Since issuance of the NPRM, the manufacturer revised the service information and the FAA has determined that it is necessary to address the unsafe condition. Therefore, we are incorporating the service letter revision into the proposed AD, and we are extending the comment period to allow the public additional time to comment.

This rule establishes a Class E airspace area extending upward from 700 feet above the surface at Prairie Du Sac, WI. The effect of this rule is to provide appropriate controlled Class E airspace for aircraft departing from and executing instrument approach procedures to Sauk-Prairie Airport, Prairie du Sac, WI and to segregate aircraft using instrument approach procedures in instrument conditions from aircraft operating in visual conditions.
