Federal Aviation Administration March 1, 2018 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Dassault Aviation Airplanes
Document Number: 2018-04150
Type: Proposed Rule
Date: 2018-03-01
Agency: Federal Aviation Administration, Department of Transportation
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
Document Number: 2018-04149
Type: Proposed Rule
Date: 2018-03-01
Agency: Federal Aviation Administration, Department of Transportation
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.
Airworthiness Directives; Agusta S.p.A. Helicopters
Document Number: 2018-03929
Type: Rule
Date: 2018-03-01
Agency: Federal Aviation Administration, Department of Transportation
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
Document Number: 2018-03928
Type: Rule
Date: 2018-03-01
Agency: Federal Aviation Administration, Department of Transportation
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.
