This notice provides a consistent process to document Regulatory Compliance Actions (CA) and Enforcement Actions in the Safety Assurance System (SAS) and provides an update on available tools and reports to track these actions. This notice focuses on the locations within the automation where information is entered to create quality records.

This order prescribes uniform Federal Aviation Administration (FAA)
procedures and responsibilities for submitting and responding to aviation-related safety
recommendations made by a Federal FAA employee (herein referred to as an “FAA employee”) or
Foreign Civil Aviation Authority (FCAA) (collectively referred to as “safety recommendations”).
Safety recommendations are based on safety concerns related to accident and incident prevention,
including a safety deficiency of products, aircraft design, operation, maintenance, service practices,
established standards, procedures, policies, and proposed corrective actions. This order specifically
addresses the FAA Safety Recommendations Program (herein referred to as “the program”) and is
managed by the FAA’s Office of Accident Investigation and Prevention (AVP), which is within the
Aviation Safety Organization (AVS). The program is one of the FAA’s processes used to identify and
correct safety deficiencies in the National Airspace System and on U.S.-manufactured aviation
products used internationally.

The purpose of this notice is to inform Flight Standards (FS)
employees of the changes and impacts due to the transition from the Flight Standards
Information Management System (FSIMS) to the Dynamic Regulatory System (DRS).

This deviation removes the UAS Integration Office, Technology Programs Branch (AUS420) as a required coordinating office in the airworthiness certification process outlined
in FAA Order 8130.34D, Airworthiness Certification of Unmanned Aircraft Systems and
Optionally Piloted Aircraft.

This deviation updates operating limitation 26, found in Appendix A of FAA Order
8130.34D, Airworthiness Certification of Unmanned Aircraft Systems and Optionally
Piloted Aircraft.

This notice announces the new optional, nonstandard operations
specification (OpSpec)/management specification (MSpec)/Letter of Authorization (LOA) D302,
applicable to Title 14 of the Code of Federal Regulations (14 CFR) parts 91 subpart K
(part 91K), 121, 125, A125 Letter of Deviation Authority (LODA) holders, 135, and 121/135
combined certificate holders (CH). OpSpec/MSpec/LOA D302 authorizes the use of an
Integrated Aircraft Health Management (IAHM) program for maintenance credit.
