Department of Transportation April 11, 2023 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2022-19-03, which applies to all Pilatus Aircraft Ltd. (Pilatus) Model PC-12, PC-12/45, PC-12/47, and PC-12/47E airplanes. AD 2022-19-03 requires incorporating new revisions to the airworthiness limitation section (ALS) of the existing airplane maintenance manual (AMM) or Instructions for Continued Airworthiness (ICA) to establish a 5-year life limit for certain main landing gear (MLG) actuator bottom attachment bolts and new life limits for the rudder bellcrank. Since the FAA issued AD 2022-19-03, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the ALS section of the existing AMM or ICA for your airplane, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to rule and invites public comment on the request to release and sell a 0.57 acre parcel of federally obligated airport property at the Malden Regional Airport & Industrial Park (MAW), Malden, Missouri.

This document provides the public with notice that on March 22, 2023, twenty host railroads submitted a joint request for amendment (RFA) to their FRA-approved Positive Train Control Safety Plans (PTCSP) reflecting the updated PTC onboard software, I-ETMS On-Board 6.5.0 and On-Board 6.5.1. This RFA includes modifications to the associated PTC Concept of Operations and PTC System Description documents, change or addition of system safety-critical functionality, modification to target safety levels and changes to the human-machine interface which requires amendments to PTC training for train crews. The functionality changes include: updates to Train Restriction Types to address the Pipeline and Hazardous Materials Safety Administration (PHMSA) final rule which restricts operating speeds of High-Hazard Flammable Train; the addition of a new system safety critical function, PTC Suspension, that prevents the generation and enforcement of targets within the limits of a PTC Suspension area with the exception of navigation failure and synchronization errors; and updates to the onboard display to show prompting to the train crew whenever a system fault related to braking prediction calculation exits. As this joint RFA involves requests for FRA's approval of the proposed material modifications to FRA-certified positive train control (PTC) systems, FRA is publishing this notice and inviting public comment on railroads' joint RFA to their PTCSPs.

In compliance with the Paperwork Reduction Act of 1995, this notice announces that the information collection request abstracted below is being forwarded to the Office of Management and Budget (OMB) for review and comment.
