Proposed Amendment of Class E Airspace; Alpine, TX
This action proposes to modify Class E airspace extending upward from 700 feet above the surface at Alpine-Casparis Municipal Airport, Alpine, TX. This action is necessary due to the decommissioning of the Brewster County non-directional radio beacon (NDB), and cancellation of the NDB approach, and would enhance the safety and management of standard instrument approach procedures for instrument flight rules (IFR) operations at this airport. Additionally, the geographic coordinates are being updated to coincide with the FAA's aeronautical database.
Airworthiness Directives; GA 8 Airvan (Pty) Ltd Airplanes
We propose to adopt a new airworthiness directive (AD) for GA 8 Airvan (Pty) Ltd Model GA8 and Model GA8-TC320 airplanes. 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 a design change to the fuselage strut pick up ribs No. 5 and 6 that requires a reduced life limit. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc., Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A and 601-3R Variants) airplanes. This proposed AD was prompted by reports of the loss of all air data system information provided to the flightcrew, which was caused by icing at high altitudes. This proposed AD would require revising the exisitng airplane flight manual (AFM) to provide the flightcrew with procedures for ``Unreliable Airspeed'' that stabilize the airplane's airspeed and attitude. The FAA is proposing this AD to address the unsafe condition on these products.
