Special Conditions: St. Louis Helicopter, LLC; Textron Aviation B300, B300C, B300C (MC-12W), and B300C (UC-12W) Airplanes; Installation of Rechargeable Lithium Batteries
These special conditions are issued for the Textron Aviation models B300, B300C, B300C (MC-12W), and B300C (UC-12W) series airplanes. The airplane, as modified by St. Louis Helicopter LLC, will have a novel or unusual design feature associated with the installation of a rechargeable lithium battery. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Proposed Amendment of Class E Airspace; Gustavus, AK
This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Gustavus Airport, Gustavus, AK. Airspace redesign is necessary as the FAA transitions from ground- based to satellite-based navigation for the safety and management of instrument flight rules (IFR) operations at this airport.
Proposed Amendment of Class D Airspace, Removal of Class E Airspace, and Establishment of Class E Airspace; Olive Branch, MS
This action proposes to amend Class D airspace, remove Class E airspace designated as an extension, and establish Class E airspace extending upward from 700 feet or more above the surface at Olive Branch Airport, Olive Branch, MS. The Olive Branch non-directional radio beacon (NDB) has been decommissioned, requiring the redesign of the airspace. This proposal would replace the outdated term Airport/ Facility Directory with the term Chart Supplement in the Class D legal description.
Proposed Amendment of Class E Airspace, Memphis, TN
This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Memphis International Airport, Memphis, TN. Airspace reconfiguration is necessary due to the decommissioning of the Elvis non-directional radio beacon (NDB), and for the safety and management of instrument flight rules (IFR) operations at this airport. Olive Branch Airport, Olive Branch, MS, would be removed from the airspace description to be reestablished in a separate rulemaking.
Proposed Amendment of Class E Airspace, Knoxville, TN
This action proposes to amend Class E surface airspace at Knoxville Downtown Island Airport, Knoxville, TN, by adding to the airspace description the exclusion of a 1-mile radius around University of Tennessee Medical Center Heliport, to allow helicopters departing from the heliport to no longer require a clearance. Also, the BENFI non-directional beacon (NDB) has been decommissioned, requiring redesign of Class E airspace extending upward from 700 feet above the surface at McGhee-Tyson Airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at these airports. This action also would update the geographic coordinates of Knoxville Downtown Island Airport, McGhee Tyson Airport, and Gatlinburg-Pigeon Forge Airport in the associated Class E airspace areas to coincide with the FAA's aeronautical database.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318, A319, and A320 series airplanes, and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and - 271N airplanes. This proposed AD was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate the specified maintenance requirements and airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
