Drugged Driving Call to Action Meeting
NHTSA is announcing a public meeting as part of the Agency's initiative to combat drug-impaired driving on U.S. roads. NHTSA is holding this public meeting to facilitate a national dialogue on best practices, lessons learned, and to develop a call-to-action with short- , mid-, and long-term plans to address drug-impaired driving in the U.S. NHTSA is bringing together key stakeholdersincluding safety partners; state and local officials; data and policy experts; law enforcement and criminal justice professionals; toxicologists; drug recognition experts; and othersto join the DOT in setting a course of action and taking measurable steps to address drug-impaired driving. Registration information for this event will be available at www.nhtsa.gov on March 1, 2018. Attendance at the meeting is limited because of space limitations of the DOT Conference Center; however, the meeting will be available for live public viewing on the NHTSA website (www.nhtsa.gov).
Airworthiness Directives; Dassault Aviation Airplanes
We propose to supersede Airworthiness Directive (AD) 2017-01- 07, which applies to all Dassault Aviation Model FAN JET FALCON airplanes, FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes; and MYSTERE-FALCON 50 airplanes. AD 2017-01-07 requires a functional test or check of the main entry door closure and warning system, and applicable door closing inspections, adjustments, operational tests, and corrective actions if necessary. Since we issued AD 2017-01-07, we have determined that the required actions must be repetitively performed to ensure continued safety. This proposed AD would require repetitive door closing inspections, adjustments, operational tests, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-400 series airplanes. This proposed AD was prompted by reports of arcing and smoke emanating from the windshields. This proposed AD would require a revision to the maintenance or inspection program, as applicable, to include an inspection of the windshield moisture seal for signs of cracks, erosion, wear, and other deterioration; doing that inspection and repair if necessary; and re-torqueing the windshield heater terminal lugs and applying sealant to the windshield heater screw heads. We are proposing this AD to address the unsafe condition on these products.
Public Meeting Regarding NHTSA's Research Portfolio
NHTSA is announcing a public meeting where the agency's Vehicle Safety Research and Behavioral Safety Research offices will present information on activities related to priority research programs in vehicle and behavioral safety, including a focused overview session on NHTSA's research in Automated Driving Systems (ADSs). Representatives from multiple research offices will present the research program area activities, near-term expected deliverables, and accept questions from the audience at the end.
Airworthiness Directives; Agusta S.p.A. Helicopters
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. Model AB139 and Model AW139 helicopters. This AD requires inspecting the thickness of the tail gearbox (TGB) central housing (housing). This AD was prompted by reports that the housing thickness does not conform to its type design. The actions of this AD are intended to detect and correct an unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, AS332L2, and EC225LP helicopters. This AD requires inspecting the sliding cabin plug door (sliding door). This AD was prompted by the failure of the sliding door's jettison mechanism due to corrosion. The actions of this AD are intended to address an unsafe condition in these products.
