Department of Transportation May 17, 2018 – Federal Register Recent Federal Regulation Documents

We are superseding Airworthiness Directive (AD) 2018-09-10 for all CFM International S.A. (CFM) Model CFM56-7B engines. AD 2018-09-10 required initial and repetitive inspections of the concave and convex sides of the fan blade dovetail to detect cracking and replacement of any blades found cracked. This AD requires the same initial and repetitive inspections but revises the compliance time for the initial inspections of certain higher-risk fan blades. This AD was prompted by a recent engine failure due to a fractured fan blade that resulted in the engine inlet cowl disintegrating and debris penetrating the fuselage, causing a loss of pressurization, and prompting an emergency descent. We are issuing this AD to address the unsafe condition on these products.

On March 6, 2018, in accordance with the Paperwork Reduction Act of 1995, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published a notice in the Federal Register (83 FR 9573) inviting comments on two information collections identified by OMB control numbers 2137-0594 and 2137-0622 that expire on May 31, 2018. PHMSA is requesting an extension with no change for these information collections. During the public comment period, PHMSA received no comments in response to the information collections. PHMSA received fifteen comments that did not pertain to the information collection requests. PHMSA is publishing this notice to provide the public with an additional 30 days to comment on the renewal of the information collections referenced above and to announce that the information collection requests will be submitted to OMB for approval.

This notice contains a summary of a petition seeking relief from specified requirements of Federal Aviation Regulations. The purpose of this notice is to improve the public's awareness of, and participation in, the FAA's exemption process. Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.

The Secretary of Transportation, as represented by the Maritime Administration (MARAD), is authorized to grant waivers of the U.S.-build requirement of the coastwise laws under certain circumstances. A request for such a waiver has been received by MARAD. The vessel, and a brief description of the proposed service, is listed below.

We propose to supersede airworthiness directive (AD) 2017-14- 03 for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. AD 2017-14-03 requires an inspection and reduces the retirement lives of certain landing gear components. This proposed AD would retain the requirements of AD 2017-14-03, reduce the retirement lives of additional landing gear components, and require repeating the inspection. The actions of this proposed AD are intended to prevent an unsafe condition on these products.

This action proposes to amend six United States Area Navigation (RNAV) routes (Q-88, Q-90, Q-114, Q-126, Q-136, and Q-150) and establish one RNAV route (Q-92) in the western United States. The routes would support standard instrument departures (SIDs) and standard terminal arrival routes (STARs) for Denver International Airport. Additionally, the routes will promote operational efficiencies for users and provide connectivity to current and proposed RNAV enroute procedures while enhancing capacity for adjacent airports.

This action proposes to remove Class D airspace, Class E airspace designated as a surface area, and Class E airspace designated as an extension to a Class D and Class E airspace at Henry Post Army Air Field (AAF), Fort Sill, OK; amend Class D airspace and Class E airspace designated as a surface area at Lawton-Fort Sill Regional Airport, Lawton, OK; and amend Class E airspace extending upward from 700 feet above the surface at Lawton-Fort Sill Regional Airport and Henry Post AAF. The FAA is proposing this action due to the closure of the air traffic control tower (ATCT) at Henry Post AAF. The name of Lawton-Fort Sill Regional Airport and the geographic coordinates of Henry Post AAF would also be updated to coincide with the FAA's aeronautical database, and the outdated term ``Airport/Facility Directory'' would be replaced with the term ``Chart Supplement.''

This action amends Class D airspace, and Class E surface area airspace at Greenwood-Leflore Airport, Greenwood, MS, by making an editorial change to the legal descriptions replacing ``Airport-Facility Directory'' with the term ``Chart Supplement''. This action also removes the part-time Notice to Airmen (NOTAM) language from Class E airspace designated as an extension to Class D airspace. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport in the Class designations noted in this proposal to coincide with the FAA's aeronautical database. Also, this action corrects the geographic coordinates published in the proposal incorrectly.
