Special Conditions: Safran Aircraft Engines, Silvercrest-2 SC-2D; Rated Takeoff Thrust at High Ambient Temperature
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.
Termination of the Preparation of an Air Tour Management Plan and Environmental Assessment for Big Cypress National Preserve, Florida
The Federal Aviation Administration (FAA), in cooperation with the National Park Service (NPS), announces that it will no longer prepare an Air Tour Management Plan (ATMP) and Environmental Assessment (EA) for commercial air tour operations over Big Cypress National Preserve in Florida. The FAA and NPS have stopped work on preparation of the ATMP and EA based upon a provision included in the FAA Modernization and Reform Act of 2012 that allowed the agencies and air tour operator(s) to enter into a voluntary agreement as an alternative to an ATMP.
Special Conditions: Game Composites Ltd, GB1 Airplane; Acrobatic Category Aerodynamic Stability
This action proposes special conditions for the Game Composites Ltd. GB1 airplane. This airplane will have a novel or unusual design feature(s) associated with static stability. This airplane can perform at the highest level of aerobatic competition. To be competitive, the airplane is designed with its lateral and directional axes being decoupled from each other; providing more precise maneuvering. 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 the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Proposed Establishment of Restricted Areas R-5602A and R-5602B; Fort Sill, OK
This action proposes to establish two restricted areas, R- 5602A and R-5602B, over a portion of the Fort Sill, OK, R-5601 restricted area complex in support of an emerging kinetic and directed energy weapons training requirement for the United States (U.S.) Army Fires Center of Excellence at Fort Sill. This additional airspace would allow for the segregation of hazardous activities from non- participating traffic.
Airworthiness Directives; Rockwell Collins, Inc. Traffic Surveillance System Processing Unit
We propose to adopt a new airworthiness directive (AD) for certain Rockwell Collins, Inc. TSS-4100 Traffic Surveillance System Processing Units that incorporate TSSA-4100 Field Loadable Software (FLS) Rockwell Collins part numbers 810-0052-002/ -003/-010/-011/-012/- 100/-101 and are installed on airplanes. This proposed AD was prompted by five instances of air traffic control observing coasting (extrapolated stale data) of automatic dependent surveillance-broadcast data (position/ velocity data). This proposed AD would require installing the TSSA-4100 FLS upgrades on the TSS-4100 units. We are proposing this AD to correct the unsafe condition on these products.
