This notice provides clarification concerning the maintenance
documents and limitations and provisions for items of emergency equipment required to be
documented in operations specification (OpSpec)/management specification (MSpec) D104. In
addition, this notice announces nonmandatory revisions to the OpSpec/MSpec D104 templates to
be issued within 180 days from the effective date of this notice. This notice contains guidance
that is pertinent to Title 14 of the Code of Federal Regulations (14 CFR) §§ 91.1015(a)(5)
and 119.49(c)(9).

This notice informs Flight Standards Service (FS) offices of the
change to certification and oversight of Unmanned Aircraft Systems (UAS) and Advanced Air
Mobility (AAM) aircraft, their associated systems, authorized training tools, and other elements.
This includes, but is not limited to, operations under Title 14 of the Code of Federal Regulations
(14 CFR) parts 91, 107, 133, 135, 137, 141, and 142, and maintenance under 14 CFR part 145.

This notice describes the conditions for withdrawal or denial of an
application and the disposition of the certification process after the certification has begun for
certifications associated with Title 14 of the Code of Federal Regulations (14 CFR) parts 91
subpart K (part 91K), 119, 125, 133, 135, 137, 141, 142, 145, and 147. Because certification
requires a significant commitment from both the applicant and the Federal Aviation
Administration (FAA), certification should be initiated only after the responsible Flight
Standards office is confident the applicant is committed to completing the certification.

This notice provides interim guidance related to the acceptance of a
Title 14 of the Code of Federal Regulations (14 CFR) part 121 or 135 regulated entity’s (RE)
Voluntary Self-Disclosure (VSD) submitted under their 14 CFR part 5 Safety Management
System (SMS). These VSDs will be disclosed via the Safety Assurance System (SAS) External
Portal, managed within the RE’s SMS, and monitored and tracked by the Federal Aviation
Administration (FAA) through SAS. Comprehensive guidance is currently under development
and will be published in FAA Order 8900.1, Flight Standards Information Management System.
In the meantime, informational resources are available in the SAS Resource Guide (SRG). This
notice contains guidance that is pertinent to 14 CFR part 193.

This advisory circular (AC) provides an acceptable means of compliance for airworthiness
criteria for low visibility takeoff, final approach, landing, and rollout in Category (CAT) II and
CAT III weather minima. While the airworthiness criteria for low visibility takeoff is generic in
nature, the criteria for the precision approach, landing, and rollout are tailored to using
Instrument Landing System (ILS), and Ground Based Augmentation System (GBAS) and it is
airplane centric. Applicants seeking airworthiness approval for rotorcraft can add appropriate
guidance to tailor their application. This AC does not address Microwave Landing System
(MLS)

This order provides guidance to Federal Aviation Administration (FAA) personnel and FAA
designees who handle alternative methods of compliance (AMOC) proposals to airworthiness
directives. This order explains how to determine if an AMOC is needed, the process to follow,
and other AMOC considerations pursuant to Title 14 of the Code of Federal Regulations
(14 CFR) Part 39.

This AC provides information relevant to the public for the maintenance recordkeeping and record-making requirements
of Title 14 of the Code of Federal Regulations (14 CFR) parts 43 and 91. This AC provides one means, but not the only means, of ensuring that the contemplated maintenance, alterations, or continue-in-service condition is in compliance with
applicable regulations and existing policy.
