Airworthiness Directives; Air Tractor, Inc. AT-400, AT-500, AT- 600, and AT-800 Series Airplanes

Fri, Dec 14 2007 11:00:00 GMT

We are revising an earlier proposed airworthiness directive (AD) that applies to certain Air Tractor, Inc. (Air Tractor) AT400, AT500, AT600, and AT800 series airplanes. The earlier NPRM proposed to supersede Airworthiness Directive (AD) 20071317, which applies to certain Air Tractor Models AT602, AT802, and AT802A airplanes. AD 20071317 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 20071317 for Models AT602, AT802, and AT802A airplanes, including the compliance times and effective dates; [[Page 71087]]
establish new inspection actions for the AT400 and AT500 series airplanes; incorporate a mandatory terminating action for all airplanes; and terminate the reporting requirement of AD 20071317. The earlier NPRM resulted from a Model AT502B with a crack located where the lower engine mount tube is welded to the engine

Airworthiness Directives; Piaggio Aero Industries S.p.A. Model P 180 Airplanes

Fri, Dec 14 2007 11:00:00 GMT

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Due to pressurization loads, the fuselage frame of the emergency exit door could suffer from fatigue and develop cracks in its corners. The superseded Italian Airworthiness Directive (AD) 1995 059 was issued to require modification of the emergency door frame in accordance with Piaggio (at the time I.A.M. Rinaldo Piaggio S.p.A.) Service Bulletin 800057 original issue.

Parts necessary to carry out the modification were a new door pan assembly and a doubler; Since these parts are no longer available, Piaggio Aero Industries S.p.A. (PAI) designed new suitable part numbers introduced by Revision 1 of Service Bulletin 800057. The present AD mandates modification

Highway Safety Programs; Proposed Amendments to Model Specifications for Screening; Devices To Measure Alcohol in

Fri, Dec 14 2007 11:00:00 GMT

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., nonbreath 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
