Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are superseding airworthiness directive (AD) AD 2012-04-13, for all Rolls-Royce plc (RR) model RB211 Trent 553-61, 553A2-61, 556- 61, 556A2-61, 556B-61, 556B2-61, 560-61, and 560A2-61; and RB211 Trent 768-60, 772-60, and 772B-60; and RB211-Trent 875-17, 877-17, 884-17, 884B-17, 892-17, 892B-17, and 895-17; and RB211-524G2-T-19, -524G3-T- 19, -524H-T-36, and -524H2-T-19 turbofan engines that have a high- pressure (HP) compressor stage 1 to 4 rotor disc installed, with a certain part number (P/N) installed. AD 2012-04-13 required repetitive inspections of the axial dovetail slots and follow-on corrective action depending on findings. This new AD expands the population of affected parts. This AD also changes, for the purposes of this AD, the definition of ``engine shop visit.'' This AD was prompted by reports of additional affected HP compressor rotor discs that require the same action. We are issuing this AD to detect cracks in the HP compressor stage 1 and 2 disc posts, which could result in failure of the disc post and HP compressor blades, damage to the engine, and damage to the airplane.
Endangered and Threatened Wildlife and Plants; Endangered Species Status for the Florida Bonneted Bat
We, the U.S. Fish and Wildlife Service, determine endangered species status under the Endangered Species Act of 1973, as amended, for the Florida bonneted bat (Eumops floridanus), a bat species from south Florida. This final rule adds this species to the List of Endangered and Threatened Wildlife and implements the Federal protections provided by the Act for this species.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes. This AD was prompted by multiple reports of cracks of overwing frames. This AD requires repetitive inspections for cracking of the overwing frames, and corrective actions if necessary. We are issuing this AD to detect and correct such cracking that could sever a frame, which may increase the loading of adjacent frames, and result in damage to the adjacent structure and consequent loss of structural integrity of the airplane.
Endangered and Threatened Wildlife and Plants; Withdrawal of the Proposed Rule To List Coral Pink Sand Dunes Tiger Beetle and Designate Critical Habitat
We, the U.S. Fish and Wildlife Service (Service), withdraw the proposed rule to list the Coral Pink Sand Dunes tiger beetle, Cicindela albissima, as a threatened species under the Endangered Species Act of 1973, as amended (Act), and designate critical habitat for the species. This withdrawal is based on our conclusion that the threats to the species as identified in the proposed rule no longer are as significant as believed at the time of the proposed rule. We base this conclusion on our analysis of current and future threats and conservation efforts. We find the best scientific and commercial data available indicate that the threats to the species and its habitat have been reduced below the statutory definition of threatened or endangered. Therefore, we are withdrawing our proposal to list the species as threatened with critical habitat.
Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters
We are adopting a new airworthiness directive (AD) for Eurocopter Model SA-365N, SA-365N1, AS-365N2, AS 365 N3, EC 155B, EC155B1, AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters with certain EADS Sogerma pilot and co-pilot seats installed. This AD requires inspecting the rear beam of each seat to determine if all of the weld beads are present and replacing the seat if any weld bead is missing. This AD is prompted by a maintenance inspection that discovered a missing weld bead on the rear beam of a pilot seat. These actions are intended to prevent failure of the pilot and co-pilot seats and subsequent injury to the pilot or co-pilot.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 727 airplanes; Model 737-100, -200, and -200C series airplanes; and Model 747-100, -100B, -100B SUD, -200B, -200C, - 200F, -300, -400, -400D, -400F, 747SR, and 747SP series airplanes. This AD was prompted by a report of an activation of the control column shaker during takeoff. This AD requires performing a general visual inspection to determine if a certain angle of attack (AOA) sensor with a paddle type vane is installed, and, for affected sensors, performing an operational test of the stall warning system, and replacing the AOA sensor with a new sensor if necessary. We are issuing this AD to prevent erroneous activation of the control column shaker during takeoff, which could result in runway overrun, failure to clear terrain or obstacles after takeoff, or reduced controllability of the airplane.
Airworthiness Directives; Airbus Airplanes
We are superseding airworthiness directive (AD) 2012-26-51 for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2012- 26-51 required revising the airplane flight manual (AFM) to advise the flightcrew of emergency procedures for addressing angle of attack (AoA) sensor blockage, and also provided for optional terminating action for the AFM revision, which involves replacing AoA sensor conic plates with AoA sensor flat plates. This new AD requires replacing AoA sensor conic plates with AoA sensor flat plates, and subsequent removal of the AFM revision. This AD was prompted by a determination that replacement of AoA sensor conic plates is necessary to address the identified unsafe condition. We are issuing this AD to prevent reduced control of the airplane.
Acquisition Process: Task and Delivery Order Contracts, Bundling, Consolidation
The U.S. Small Business Administration (SBA) is amending its regulations governing small business contracting procedures. Specifically, this rule amends SBA's regulations to establish policies and procedures for setting aside, partially setting aside and reserving Multiple Award Contracts for small business concerns. SBA is also is establishing policies and procedures for setting aside task and delivery orders for small business concerns under Multiple Award Contracts. In addition, SBA is addressing how it will determine size under certain Agreements and when recertification of status will be required. Finally, SBA is establishing a new definition of consolidation and reorganizing its prime contracting assistance regulations.
