Department of Transportation March 11, 2022 – Federal Register Recent Federal Regulation Documents

In accordance with the Paperwork Reduction Act of 1995, PHMSA invites public comments on its intent to request Office of Management and Budget (OMB) approval to revise and renew an information collection currently under OMB Control Number 2137-0596 titled: ``National Pipeline Mapping System Program.'' The information collection currently requires operators to submit geospatial data, attributes, metadata, public contact information, and a transmittal letter appropriate for use in the National Pipeline Mapping System (NPMS). Acceptable formats and additional information are specified in the NPMS Attribute Standards document available at www.npms.phmsa.dot.gov. The proposed revisions would modify one attribute approved in January 2020 that pipeline operators must submit to PHMSA, extend the expiration date of the information collection established by OMB, and require gas transmission operators to submit additional attributes to the NPMS.

The FAA is superseding Airworthiness Directive (AD) 2019-03-01 and AD 2021-05-51 for certain Pratt & Whitney Division (PW) PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 model turbofan engines. AD 2019-03-01 required performing initial and repetitive thermal acoustic image (TAI) inspections for cracks in certain 1st- stage low-pressure compressor (LPC) blades and removal of those blades that fail inspection. AD 2021-05-51 required performing a one-time TAI inspection for cracks in certain 1st-stage LPC blades and removal of those blades that fail inspection. This AD was prompted by three in- flight failures of a 1st-stage LPC blade, with one failure resulting in an engine fire during flight, and subsequent manufacturer publication of service information specifying improved inspections for three critical locations on the 1st-stage LPC blade. This AD requires initial and repetitive ultrasonic (UT) inspections and TAI inspections for cracks in certain 1st-stage LPC blades and removal of those blades that fail inspection. The FAA is issuing this AD to address the unsafe condition on these products.

This document announces ASTM International (ASTM) consensus standards for use as a means of compliance to the applicable airworthiness standards for normal category airplanes.
