This advisory circular (AC) provides ways for pilots and airplane operators to identify,
understand, and manage the risks associated with the landing phase of flight. It also provides
information that both certificated and noncertificated operators may use to develop personal or
standard operating procedures (SOP) to mitigate a runway excursion

The Federal Aviation Administration (FAA), Office of Aerospace Medicine (AAM) has prepared this
Order for Drug Abatement Division (AAM-800) personnel to follow when assessing drug and alcohol

“Procedures for Transportation Workplace Drug and Alcohol Testing Programs;” the FAA’s 14 CFR
part 120, “Drug and Alcohol Testing Program;” and other relevant Federal Aviation Regulations.
Unless otherwise directed by the AAM-800 Director, all program personnel must adhere to the
procedures in this order. The FAA invites comments and suggestions from those who use the order.

The Boston Aircraft Certification Office Branch (ACOB) requested a deviation to FAA Order
8110.56B, Restricted Category Type Certification and FAA Order 8110.48A, How to Establish
the Certification Basis for Changed Aeronautical Products, for the Sikorsky S-70M, a derivative
of the U.S. Army UH-60M. The Boston ACOB requested relief from the requirement detailed in
Order 8110.56B, chapter 4, paragraph 9(b) and Order 8110.48A, paragraph 4-8.d, which state,
“The baseline certification basis for modifications is the 14 CFR regulations applicable to the
aircraft (i.e., part 23, part 25, part 27, part 29, or CARs, as appropriate) that were in effect on the
date that the first aircraft of the particular military model (i.e., MDS) was accepted for
operational use by the U.S. Armed Forces.” This memo corrects the deviation memo dated
3/28/23, from number AIR-620-23-DM02 to AIR-600-DM02.

This memorandum authorizes a deviation from FAA Order 8130.2J, Airworthiness
Certif,.cation ofAircraft, Appendix D, Operating Limitation #42. This limitation can be issued
to amateur-built aircraft entering Phase 1 flight test to demonstrate compliance with 14
CFR 91.319(b).

This notice provides guidance to Federal Aviation Administration
(FAA) Flight Standards (FS) Safety Assurance offices to evaluate an applicant for a Letter of
Authorization (LOA) A130 because the operator proposes to use an Unmanned Aircraft System
(UAS) equipped with a dangerous weapon1
under Section 363 of the FAA Reauthorization Act
of 20182
(Section 363) for agricultural aircraft operations and therefore requires the
Administrator’s authorization. The FAA has determined that an aerial ignition system qualifies
as a dangerous weapon under Section 363. Therefore, this notice focuses on the application
process to receive authorization for the carriage of an aerial ignition system on a UAS. This
notice also addresses initial Title 14 of the Code of Federal Regulations (14 CFR) part 137
certification, adding a UAS equipped with an aerial ignition system to an existing part 137
certificate, and conducting part 137 pilot in command (PIC) knowledge and skill tests using a
UAS equipped with an aerial ignition system. Additionally, this notice introduces new part 137
LOA A130 to be issued via the Web-based Operations Safety System (WebOPSS).

This order describes the organizational structure and functions of the
Aircraft Certification Service (AIR).
