This action proposes special conditions for the Safran Aircraft Engines (SAE), Silvercrest-2 SC-2D engine model. This engine will have a novel or unusual design feature associated with an additional takeoff rating that increases the exhaust gas temperature (EGT) limit to maintain takeoff thrust in certain high ambient temperature conditions for a maximum accumulated usage of 20 minutes in any one flight. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This action proposes to: Remove Class D airspace for Enid Woodring Municipal Airport, OK, and Enid Vance AFB, OK; establish Class D airspace for Enid Woodring Regional Airport, Enid, OK, and Vance AFB, Vance AFB, OK; amend Class E airspace designated as a surface area for Enid Woodring Regional Airport; establish Class E airspace designated as a surface area for Vance AFB; remove Class E airspace designated as an extension of Class D and E surface area at Enid Woodring Municipal Airport, OK, and Enid Vance AFB, OK; establish Class E airspace designated as an extension of Class D and E surface area at Enid Woodring Regional Airport and Vance AFB; and amend Class E airspace extending upward from 700 feet above the surface at Enid Woodring Regional Airport. Due to the differing operating hours of the two airports, the airspace descriptions would be separated for safety and management of instrument flight rules (IFR) operations at these airports. Also, airspace redesign is necessary to accommodate new standard instrument approach procedures (SIAPS) at Woodring Regional Airport.
