The FAA proposes to adopt a new airworthiness directive (AD) for certain De Havilland Aircraft of Canada Limited Model DHC-8-400 series airplanes. This proposed AD was prompted by a report that electrical bonding jumpers had been installed on fuel scavenge lines even after the removal was required by previous AD rulemaking and that electrical bonding jumpers may have been installed in production or in service at other locations. This proposed AD would require an inspection for electrical bonding jumpers and brackets on the fuel scavenge and vent lines at specific wing locations, and if installed, removal or modification of those jumpers and brackets. This proposed AD would also require a records check to determine if certain maintenance tasks were performed and removal, modification, or rework if those tasks were performed. This proposed AD would also prohibit the use of earlier versions of certain maintenance tasks. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B and GEnx-2B model turbofan engines. This proposed AD was prompted by a manufacturer investigation that revealed that certain high-pressure turbine (HPT) stage 2 disks, forward seals, and stages 6-10 compressor rotor spools were manufactured from powder metal material suspected to contain iron inclusion. This proposed AD would require the replacement of the affected HPT stage 2 disks, forward seals, and stages 6-10 compressor rotor spools. The FAA is proposing this AD to address the unsafe condition on these products.

On January 12, 2021, NHTSA released its draft Cybersecurity Best Practices for the Safety of Modern Vehicles guidance (``Draft Best Practices'' or ``guidance'') in an effort to support industry-led efforts to improve the industry's cybersecurity posture as well as provide NHTSA's views on how the automotive industry can develop and apply sound, risk-based cybersecurity management processes during the vehicle's entire lifecycle. These guidelines are intended to be applicable to all individuals and organizations involved in the design, development, manufacture and assembly of a motor vehicle and its electronic systems and software. These entities include, but are not limited to, small and large-volume motor vehicle and motor vehicle equipment designers, suppliers, manufacturers, and modifiers. This document summarizes comments received in response to the draft guidance, responds to those comments, and describes changes made to the draft guidance in response to those comments. This document also announces the issuance of the final version of the Cybersecurity Best Practices for the Safety of Modern Vehicles guidance. While this is the final version of this iteration of the Best Practices, NHTSA routinely assesses cybersecurity risks as well as emerging best practices and will consider future updates as motor vehicles and their cybersecurity evolve.

Hercules Tire & Rubber Company, (Hercules), has determined that certain Ironman iMOVE PT specialty trailer tires do not fully comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 139, New Pneumatic Radial Tires for Light Vehicles. Hercules filed an original noncompliance report dated May 10, 2022, and amended the report on May 12, 2022. Hercules petitioned NHTSA on June 21, 2022, for a decision that the subject noncompliance is inconsequential as it relates to motor vehicle safety. This document announces receipt of Hercules's petition.
