# §450.107. Hazard control strategies.

- (a) **General.** To meet the safety criteria of § [450.101(a)](/cfr/14/450.101.md?p=a), [(b)](/cfr/14/450.101.md?p=b), or [(c)](/cfr/14/450.101.md?p=c) for the flight, or any phase of flight, of a launch or reentry vehicle, an operator must use one or more of the hazard control strategies identified in [§ 450.108](/cfr/14/450.108.md) through [§ 450.111](/cfr/14/450.111.md).
- (b) **Hazard control strategy determination.** For each phase of flight during a launch or reentry, an operator must use a functional hazard analysis to determine a hazard control strategy or strategies that account for—
  - (1) All functional failures associated with reasonably foreseeable hazardous events that have the capability to create a hazard to the public;
  - (2) Safety-critical systems; and
  - (3) **A timeline of all safety-critical events.**
- (c) **Flight hazard analysis.** An operator must conduct a flight hazard analysis in accordance with [§ 450.109](/cfr/14/450.109.md) of this part for the flight, or phase of flight, of a launch or reentry vehicle if the public safety hazards cannot be mitigated adequately to meet the public risk criteria of § [450.101(a)](/cfr/14/450.101.md?p=a), [(b)](/cfr/14/450.101.md?p=b), and [(c)](/cfr/14/450.101.md?p=c) using physical containment, wind weighting, or flight abort.
- (d) **Application requirements.** An applicant must submit in its application—
  - (1) **The results of the hazard control strategy determination, including—**
    - (i) All functional failures identified under [paragraph (b)(1)](#b-1) of this section;
    - (ii) The identification of all safety-critical systems; and
    - (iii) **A timeline of all safety-critical events.**
  - (2) **A description of its hazard control strategy or strategies for each phase of flight.**
