14 C.F.R. § 415.35 Acceptable flight risk.
Title 14 - Aeronautics and Space
(a) Flight risk through orbital insertion or impact. Acceptable flight risk through orbital insertion for an orbital launch vehicle, and through impact for a suborbital launch vehicle, is measured in terms of the expected average number of casualties (Ec) to the collective members of the public exposed to debris hazards from any one launch. To obtain safety approval, an applicant shall demonstrate that the risk level associated with debris from an applicant's proposed launch shall not exceed an expected average number of 0.00003 casualties per launch (Ec ≤ 30 × 10−6). (b) Hazard identification and risk assessment. To demonstrate compliance with this section, an applicant shall submit an analysis that identifies hazards and assesses risks to public health and safety and safety of property associated with nominal and non-nominal flight under its launch proposal. (c) A launch vehicle shall be designed to ensure that flight risks meet the criteria set forth in this section. An applicant shall identify and describe the following: (1) Launch vehicle structure, including physical dimensions and weight; (2) Hazardous and safety critical systems, including propulsion systems; and (3) Drawings and schematics for each system identified under paragraph (c)(2) of this section. (d) A launch vehicle shall be operated in a manner that ensures that flight risks meet the criteria set forth in this section. An applicant shall identify all launch operations and procedures that must be performed to ensure acceptable flight risks.
