This notice announces the publication of Title 14 of the Code of
Federal Regulations (14 CFR) Part 3 Subpart C, U.S. Agents for Service on Individuals With
Foreign Addresses Who Hold or Apply for Certain Certificates, Ratings, or Authorizations.

This notice provides guidance to aviation safety inspectors (ASI)
with oversight responsibilities of Title 14 of the Code of Federal Regulations (14 CFR) part 141
schools and discusses the requirements for conducting ramp inspections of school aircraft.

On November 20, 2023, the Federal Aviation Administration
(FAA) issued Notice N 8110.118, Submittal and Disclosure of Safety Critical Information by
Applicants for Transport Category Airplane Type Certificates to supplement FAA Order
8110.4C, Type Certification and provide FAA interim policy regarding some of the requirements
of Section 105(a) of The Aircraft Certification, Safety, and Accountability Act, Pub. L. 116-260
(the Act). Section 105(a) of the Act established paragraph 44704(e) of Title 49, United States
Code (49 U.S.C.). The Act mandates that the Administrator require the submittal and disclosure
of safety critical information by applicants for, or holders of, new or amended, but not
supplemental, type certificates (TC) for transport category airplanes covered under title 14, Code
of Federal Regulations (14 CFR) part 25. Section 105(a) also mandates the FAA to establish
multiple milestones throughout the certification process at which a proposed airplane system will
be assessed to determine whether any change to such system during the certification process is
such that the system should be considered novel or unusual by the Administrator.
This Notice extends the interim policy in Notice N 8110.118, and updates references to
specific 14 CFR part 25 sections based on a final rule issued by the FAA (89 FR 68706) on
August 27, 2024 to amend certain airworthiness regulations to standardize the criteria for
conducting safety assessments for systems, including flight controls and powerplants, installed
on transport category airplanes. The FAA has initiated rulemaking proposed to mandate, after
notice and an opportunity for the public to comment, Section 105(a)’s requirements for transport
category airplane new and amended TC applicants and holders. 1 However, this Notice addresses
methods of clearly identifying, as “safety critical,” certain information that already is, and can
continue to be, provided by applicants during the application process for a new or amended TC
project for a transport category airplane. This Notice also discusses usage of milestones
throughout the project

This AC describes a standardized
procedure for requesting approval of technical data associated with major repairs/major
alterations. This AC also provides information that can help determine if a proposed
repair/alteration requires approved data, guidance, and standardized procedures for obtaining
field approval (or approval by other means) of data, and instructions for completing the field
approval checklist.

This AC provides guidance in
developing an anticollision light maintenance program. This AC describes an acceptable
means, but not the only means, to comply with Title 14 of the Code of Federal
Regulations (14 CFR). However, if you use the means described in this AC to show
compliance, you must follow it in all important respects.

This advisory circular (AC) provides airworthiness and operational authorization guidance
material for operators, pilots, certificate holders, and/or program managers conducting Title 14
of the Code of Federal Regulations (14 CFR) part 91, §§ 91.180 and 91.706 Reduced Vertical
Separation Minimum (RVSM) operations. RVSM airspace is any airspace or route between
flight level (FL) 290 and FL 410 inclusive where aircraft are separated vertically by 1,000 feet.
This AC has been updated to include guidance on eligibility and compliance for §§ 91.180
and 91.706 RVSM operations when operators seek RVSM authorization under the provisions of
the new Part 91 Appendix G, Section 9, Aircraft Equipped with Automatic Dependent
Surveillance – Broadcast Out.
The Federal Aviation Administration (FAA) intends to transition current authorizations, issued
under part 91 appendix G, section 3, to monitor operations under the provisions of part 91
appendix G, section 9. This action reduces the operator and FAA administrative burdens
associated with maintaining the part 91 appendix G, section 3 authorizations.

This AC provides criteria and
describes acceptable methods for obtaining approval to use Offshore Standard Approach
Procedures (OSAP), Airborne Radar Approaches (ARA), and Helicopter En Route Descent
Areas (HEDA) to descend in uncontrolled airspace to an altitude where the pilot can proceed to
land using visual references to the surface.

This AC provides information
on the hazards and risks of in-flight fires on transport category aircraft. The information
includes recommended crewmember procedures and training for combating general and
high-energy fires (HEF) caused by lithium batteries. This AC is applicable to operators
conducting operations under Title 14 of the Code of Federal Regulations (14 CFR)
parts 91, 91 subpart K (part 91K), 121, 125, and 135.
