Proposed Amendment and Establishment of Multiple Air Traffic Service (ATS) Routes; Western United States
This action proposes to amend six United States Area Navigation (RNAV) routes (Q-88, Q-90, Q-114, Q-126, Q-136, and Q-150) and establish one RNAV route (Q-92) in the western United States. The routes would support standard instrument departures (SIDs) and standard terminal arrival routes (STARs) for Denver International Airport. Additionally, the routes will promote operational efficiencies for users and provide connectivity to current and proposed RNAV enroute procedures while enhancing capacity for adjacent airports.
Airworthiness Directives; Honda Aircraft Company LLC Airplanes
We are superseding Airworthiness Directive (AD) 2018-06-10 for certain Honda Aircraft Company LLC Model HA-420 airplanes. AD 2018-06- 10 required incorporating a temporary revision into the airplane flight manual and replacing faulty power brake valves upon condition. This AD retains the actions required in AD 2018-06-10 and adds airplanes to the Applicability section. This AD was prompted by an inadvertent mistake in the serial number applicability (both in the service bulletin and in the AD). We are issuing this AD to address the unsafe condition on these products by correcting the inadvertent serial number error.
Proposed Establishment of Class E Airspace, Los Angeles, CA
This action proposes to establish Class E en route airspace extending upward from 1,200 feet above the surface to accommodate instrument flight rules (IFR) aircraft under control of the Los Angeles Air Route Traffic Control Center (ARTCC), Los Angeles, CA. Establishment of this airspace area would ensure controlled airspace exists in those areas where the Federal airway structure is inadequate.
Airworthiness Directives; Bombardier, Inc., Airplanes
We are superseding Airworthiness Directive (AD) 2016-11-02, which applied to all Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes; Model CL-600-2D15 (Regional Jet Series 705) airplanes; Model CL-600-2D24 (Regional Jet Series 900) airplanes; and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. AD 2016-11-02 required repetitive inspections of the upper and lower engine pylons for protruding, loose, or missing fasteners; and repair if necessary. This AD continues to require the repetitive inspections of the upper and lower engine pylons for protruding, loose, or missing fasteners; and repair if necessary. This AD also requires replacement of affected fasteners, which terminates the inspections. This AD was prompted by reports of loose or missing fasteners and collars on the upper and lower engine pylon structure common to the upper and lower pylon skin panels and engine thrust fitting. We are issuing this AD to address the unsafe condition on these products.
