February 15, 2017 – Federal Register Recent Federal Regulation Documents

Pursuant to Section 102(2)(c) of the National Environmental Policy Act of 1969; the Council on Environmental Quality Final Regulations (40 CFR parts 1500 through 1508); and the United States Section, Operational Procedures for Implementing Section 102 of NEPA, published in the Federal Register September 2, 1981 (46 FR 44083); the United States Section hereby gives notice that the Final Environmental Assessment and Finding of No Significant Impact (FONSI) for Alamito and Terneros Sediment and Vegetation Removal below Presidio Flood Control Project, Presidio, Texas is available. An environmental impact statement will not be prepared unless additional information which may affect this decision is brought to our attention within 30-days from the date of this Notice.

We propose to supersede Airworthiness Directive (AD) 2015-23- 13, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2015-23-13 currently requires modification of the pin programming of the flight warning computer (FWC) to activate the stop rudder input warning (SRIW) logic; and an inspection to determine the part numbers of the FWC and the flight augmentation computer (FAC), and replacement of the FWC and FAC if necessary. Since we issued AD 2015-23-13, we have determined that, for certain airplanes, additional modification instructions must be accomplished to allow installation of the minimum FWC and FAC configuration compatible with SRIW activation. This proposed AD would, for certain airplanes, also require accomplishment of additional modification instructions to install the minimum FWC and FAC configuration compatible with SRIW activation. We are proposing this AD to address the unsafe condition on these products.
