Guidance on Delegation of 14 CFR Part 36 Noise Authority to
Organization Designation Authorization (ODA) Holders

This notice provides guidance for the Continued Operational Safety (COS) of Title 14 of the Code of Federal Regulations (14 CFR) parts 121, 135, and 145 operations. This notice includes guidance for part 121 certificate holders’ Safety Management Systems (SMS) as required by 14 CFR part 5, and for parts 135 and 145 certificate holders’ Safety Management System Voluntary Program (SMSVP). This notice also includes guidance for the revised Safety Attributes for all 14 CFR certificate holder oversight in the Safety Assurance System (SAS).

This notice supplements current policy relating to the Aviation SafetyAction Program (ASAP) and the Voluntary Disclosure Reporting Program (VDRP). The changes are to policy contained within Federal Aviation Administration (FAA) Order 8900.1, Volume 11, Chapter 1, Section 1, Voluntary Disclosure Reporting Program for Air Carriers and Regulated Entities; and Volume 11, Chapter 2, Section 1, Safety Assurance System: Aviation SafetyAction Program. These changes primarily address the impact and application of the Compliance Philosophy, calling for the removal of Administrative Action as a required outcome for accepted voluntary disclosures under the VDRP, and eliminate Administrative Action and the Enforcement Decision Process (EDP) tool from application to accepted reports within ASAP, and from the current edition of FAA Order 2150.3, FAA Compliance and Enforcement Program.

This notice supplements current policy and removes requirements
for applicants and certificate holders to use the Safety Assurance System (SAS) external portal
and Data Collection Tools (DCT).

The primary audience for this notice includes Flight Standards division managers,
Office Managers (OM), principal inspectors (PI), and certification project managers (CPM) who
have oversight responsibility for applicants and operators certificated under Title 14 of the
Code of Federal Regulations (14 CFR) for operations under 14 CFR parts 121, 135, and 145.
The secondary audience includes all Flight Standards divisions, branches, and offices.

operations and a mandatory revision to operations specification (OpSpec)/management
specification (MSpec)/letter of authorization (LOA) A056. This notice provides guidance for

assigned to operators conducting operations under Title 14 of the Code of Federal Regulations
(14 CFR) parts 91, 91 subpart K (part 91K), 121, 125 (including Letter of Deviation Authority
(LODA) part 125 holders), and 135.
