Probability of failure analysis.

CFR · 2024-01-01 · US · Title 14

(a) (1) For a vehicle or vehicle stage with fewer than two flights, the failure probability estimate must account for the outcome of all previous flights of vehicles developed and launched or reentered in similar circumstances. (2) For a vehicle or vehicle stage with two or more flights, vehicle failure probability estimates must account for the outcomes of all previous flights of the vehicle or vehicle stage in a statistically valid manner. The outcomes of all previous flights of the vehicle or vehicle stage must account for data on any mishap and anomaly. (b) (c) (1) The flight of a launch vehicle begins at a time in which a launch vehicle lifts off from the surface of the Earth; and (2) The flight of a reentry vehicle or deorbiting upper stage begins at a time in which a vehicle attempts to initiate a reentry. (d) (1) The data available from all previous flights of vehicles developed and launched or reentered in similar circumstances; and (2) Data from previous flights of vehicles, stages, or components developed and launched, reentered, flown, or tested by the subject vehicle developer or operator. Such data may include previous experience involving similar— (i) Vehicle, stage, or component design characteristics; (ii) Development and integration processes, including the extent of integrated system testing; and (iii) Level of experience of the vehicle operation and development team members. (e) (f) (1) A description of the methods used in probability of failure analysis,
