# §414.23. Technical criteria for reviewing a safety element approval application.


The FAA will determine whether a safety element is eligible for and may be issued a safety element approval. The FAA will base its determination on performance-based criteria, against which it may assess the effect on public health and safety and on safety of property, in the following hierarchy:

- (a) **FAA or other appropriate Federal regulations.**
- (b) **Government-developed or adopted standards.**
- (c) **Industry consensus performance-based criteria or standard.**
- (d) **Applicant-developed criteria.** Applicant-developed criteria are performance standards customized by the manufacturer that intends to produce the system, system component, or part. The applicant-developed criteria must define—
  - (1) Design and minimum performance;
  - (2) Quality assurance system requirements;
  - (3) Production acceptance test specifications; and
  - (4) **Continued operational safety monitoring system characteristics.**
