This final rule adopts permanent amendments and a Special Federal Aviation Regulation (SFAR) for a period of ten years to: facilitate the certification of powered-lift pilots, clarify operating rules applicable to operations involving a powered-lift, and finalize other amendments which are necessary to integrate powered-lift into the National Airspace System (NAS). In this final action, the FAA finalizes its alternate framework to stand-up initial groups of powered-lift pilots and flight instructors. Most notably, the FAA adopts alternate frameworks to facilitate the certification of pilots seeking qualifications in a powered-lift with single functioning flight controls and a single pilot station. In response to commenters, the FAA provides clarification for certain operating rules and adopts a performance-based approach to certain operating rules to enable powered-lift operations. In addition to finalizing provisions for powered-lift, this action also makes changes to practical tests in aircraft that require type ratings, including airplanes and helicopters, training center rotorcraft instructor eligibility, training and testing requirements, and training center use of rotorcraft in flight training.

This advisory circular (AC) is a summary of the current available data regarding identification
and treatment of corrosive attack on aircraft structures and engine materials. Corrosion
inspection frequency, corrosion identification, and especially corrosion treatment continues to be
the responsibility of the operator. These inspections should be accomplished per this AC, the
manufacturer’s recommendations, or the operator’s own maintenance program. The procedures
in this AC are an acceptable means, but not the only acceptable means, of corrosion treatment.
The information in this AC is applicable to aircraft for which the manufacturer has not published
corrosion control information. Where the airframe or engine manufacturer has published a
recommended corrosion inspection schedule and treatment program, the applicable program
must take precedence over the recommendation of this AC.

This final rule implements, without interpretation, the provisions of sections 815 and 828 of the FAA Reauthorization Act of 2024 (“the Act”). To conform the FAA’s regulations to the self-enacting provisions in the Act, this final rule amends certain regulations to: align aircraft conditions and limitations with the term “covered aircraft” as defined in section 2307(j) of the FAA Extension, Safety, and Security Act of 2016 to increase the number of allowable passengers from 5 to 6, increase the number of occupants from 6 to 7, and increase the maximum takeoff weight from 6,000 pounds to 12,500 pounds, while excluding certain transport category rotorcraft. This final rule facilitates updates to current standards the medical form a State-licensed physician uses in completing a comprehensive medical examination. Further, this final rule amends regulations to incorporate the statutory expansion of BasicMed medical eligibility to examiners conducting practical tests or proficiency checks if they meet the requirements for operating covered aircraft under BasicMed, as provided in the Act.

This advisory circular (AC) provides users of the NAS
guidance regarding how to conduct operations in accordance with 14 CFR §§ 91.225 and 91.227.
The appendices in this AC provide guidance for additional operations enabled by ADS-B,
including ADS-B In.

This notice announces the release of a nonmandatory revision for
operations specification (OpSpec) A001 for Title 14 of the Code of Federal Regulations
(14 CFR) part 129. This notice also announces the release of a mandatory revision for
OpSpec D085 for part 129 (both the part 129 and § 129.14 set of available OpSpecs).

This InFO provides information to all part 121 operators that utilize part 145 foreign repair stations located in foreign countries on the new requirements of USC 49 § 44733.
