# §450.115. Flight safety analysis methods.

- (a) **Scope of the analysis.** An operator's flight safety analysis method must account for all reasonably foreseeable events and failures of safety-critical systems during nominal and non-nominal launch or reentry that could jeopardize public safety.
- (b) **Level of fidelity of the analysis.** An operator's flight safety analysis method must have a level of fidelity sufficient to—
  - (1) Demonstrate that any risk to the public satisfies the safety criteria of [§ 450.101](/cfr/14/450.101.md), including the use of mitigations, accounting for all known sources of uncertainty, using a means of compliance accepted by the Administrator; and
  - (2) Identify the dominant source of each type of public risk with a criterion in § [450.101(a)](/cfr/14/450.101.md?p=a) or [(b)](/cfr/14/450.101.md?p=b) in terms of phase of flight, source of hazard (such as toxic exposure, inert, or explosive debris), and failure mode.
- (c) **Application requirements.** An applicant must submit a description of the flight safety analysis methodology, including identification of:
  - (1) The scientific principles and statistical methods used;
  - (2) All assumptions and their justifications;
  - (3) The rationale for the level of fidelity;
  - (4) The evidence for validation and verification required by [§ 450.101(g)](/cfr/14/450.101.md?p=g);
  - (5) The extent to which the benchmark conditions are comparable to the foreseeable conditions of the intended operations; and
  - (6) **The extent to which risk mitigations were accounted for in the analyses.**
