The Federal Aviation Administration (FAA) announces its findings on the noise compatibility program submitted by the City of Hawthorne, California. On April 11, 2014, the FAA determined that the noise exposure maps submitted by the City of Hawthorne were in compliance with applicable requirements. On December 18, 2017, the FAA approved the Hawthorne Municipal Airport Noise Compatibility Program. All 11 of the recommendations of the program were approved. No program elements relating to new or revised flight procedures for noise abatement were proposed by the airport operator.

This is notification of criteria used to evaluate the Millennium Engineering and Integration Company (MEI) safety approval application. This Notice publishes the criteria that the FAA used to evaluate the safety approval application pursuant to FAA regulations. Background: MEI applied for, and received, a safety approval for its ability to provide its Flight Analyst Workstation (FAWS) as a component of the process to build flight rules, generate the Mission Data Load (MDL), and verify the MDL prior to loading it onto a launch vehicle's autonomous flight safety unit (AFSU). The FAA issued MEI the safety approval, subject to the provisions of Title 51 U.S.C. Subtitle V, ch. 509, and the orders, rules and regulations issued under it. This Notice is published pursuant to Title 14 Code of Federal Regulations (14 CFR 414.35). MEI may offer FAWS as a component of the process of generating and verifying MDLs for AFSUs to a prospective launch or reentry operator to meet the applicable requirements of 14 CFR 417.123(b), (d), and (e), and Sec. 417.309(h). Criteria Used To Evaluate Safety Approval Application: The performance criteria used to evaluate the FAWS as a component of the process of generating and verifying MDLs for AFSUs included the following FAA regulations, NASA standard, U.S. Air Force manuals or instructions, industry standard, and MEI-developed standards: 14 CFR 417.309(h) Flight Safety System AnalysisSoftware and Firmware and 14 CFR 417.123 Computing Systems and Software. NASA-STD-8719.13C Software Safety Standard. AFSPCMAN 91-710 (v1) Range Safety Policies and Procedures, AFSPCMAN 91-710 (v2) Range Safety User Requirements Manual, Volume 2Flight Safety Requirements, AFSPCMAN 91-712 Launch Safety Software and Computing System Requirements, and 45 SWI 91-701 45th Space Wing Launch Safety Software Management.

MEI-000071 Configuration Management, MEI-000120 Requirements Development and Management, MEI-000124 Technical Solution, MEI-000149 Agile Software Development Process, and MEI-000125 Verification and Validation.

We are adopting a new airworthiness directive (AD) for Viking Air Limited Models DHC-6-1, DHC-6-100, DHC-6-200, DHC-6-300, and DHC-6- 400 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as aileron cable wear; fouling at the wing root rib, fuselage skin, and wing root rib fairlead; and/or fraying of the cable from the root rib fairlead. We are issuing this AD to require actions to address the unsafe condition on these products.
