Pipeline Safety: Gas and Hazardous Liquid Pipeline Risk Models
PHMSA is publishing this notice to seek public comments on a report developed to support improvements in gas and hazardous liquid pipeline risk models titled ``Pipeline Risk ModelingOverview of Methods and Tools for Improved Implementation'' (Pipeline Risk Modeling Report). Pipeline risk models are a foundational part of the assessment of operational pipeline risk. Federal pipeline safety integrity management (IM) regulations require pipeline operators to use risk assessments. Based on the results of pipeline inspections and failure investigation findings, both PHMSA and the National Transportation Safety Board (NTSB) have identified general weaknesses in the risk models often used by pipeline operators in performing risk assessments for their IM programs. The Pipeline Risk Modeling Report considers the major types of pipeline risk models, and the effectiveness of each type in supporting risk assessments, as applied to pipeline operator decisions.
Airworthiness Directives; B/E Aerospace Fischer GmbH Attendant Seats and Pilot Seats
We are adopting a new airworthiness directive (AD) for certain B/E Aerospace Fischer GmbH Attendant Seats NG and Pilot Seats 120/335. This AD requires removing and replacing the energy absorber (EA) assemblies on affected pilot seats and the removing and replacing affected attendant seats. This AD was prompted by the discovery that rivets with insufficient strength were used during the manufacture of EA assemblies installed on certain seats. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus SAS Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This proposed AD was prompted by a review of the Airbus A350 structure design principles database for type definition that revealed that the balancer fitting part, installed on the tail cone, on a certain frame (FR) has several corrosion-resistant stainless steel nuts that do not meet the requirements for protection against corrosion. This proposed AD would require application of a new additional overcoat sealant and elastic varnish on the affected nuts and fasteners. We are proposing this AD to address the unsafe condition on these products.
Petition for Exemption; Summary of Petition Received; The Boeing Company
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.

Airworthiness Directives; Bombardier, Inc., Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by in-service findings that a cotter pin at the main fitting joint of the nose landing gear (NLG) retraction actuator to the NLG strut showed evidence of shearing after a NLG retraction-extension cycling. This proposed AD would require revising the maintenance or inspection program, as applicable, a general visual inspection for damage of a certain cotter pin present on certain configurations of the NLG strut assembly and for the modification number shown on the identification plate for the NLG strut, and modification of the NLG retraction actuator hardware on any damaged NLG strut assembly. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt an airworthiness directive (AD) for all The Boeing Company Model 757-200 series airplanes. This proposed AD was prompted by reports of uncommanded movement of the captain's and first officer's seats. This proposed AD would require, for the captain's and first officer's seats, repetitive horizontal actuator identifications, repetitive checks of the horizontal movement system (HMS), a detailed inspection of the HMS, as applicable, and applicable on-condition actions. This proposed AD would also require a general visual inspection to determine seat part numbers of the captain's and first officer's seats, a cable adjustment check on seats with certain seat part numbers, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.
Amendment of Chicago Class B and Chicago Class C Airspace; Chicago, IL
This action amends the Chicago, IL, Class B airspace area description by changing references for defining the center point of the Chicago Class B airspace from the Chicago O'Hare VHF Omnidirectional Range/Distance Measuring Equipment (VOR/DME) to ``Point of Origin.'' The ``Point of Origin'' uses the same geographic coordinates as the Chicago O'Hare VOR/DME location. This action also amends the Chicago Midway Airport, IL, Class C airspace description by changing the reference for defining a portion of the Class C airspace boundary from using the Chicago O'Hare VOR/DME to using the geographic coordinates of the Chicago O'Hare VOR/DME instead. The FAA is taking this action due to the planned decommissioning of the Chicago O'Hare VOR/DME. Additionally, the Chicago Class B and Chicago Midway Airport Class C airspace descriptions are edited further to reflect the Chicago Midway International Airport name change to match the current information in the FAA's aeronautical database, and the Chicago Midway Airport Class C airspace designation is amended to remove the airport name from the airspace designation to comply with FAA regulatory guidance. These changes are editorial only and do not alter the current charted boundaries, altitudes, or ATC procedures for the Chicago Class B or the Chicago Midway International Airport Class C airspace areas.
