Flight safety system analysis.

CFR · 2024-01-01 · US · Title 14

(a) (2) Each analysis must follow an FAA approved system safety and reliability analysis methodology. (b) (1) Account for the probability of a flight safety system anomaly occurring and all of its effects as determined by the single failure point analysis and the sneak circuit analysis required by paragraphs (c) and (g) of this section; (2) Demonstrate that each system satisfies the predicted reliability requirement of 0.999 at the 95 percent confidence level; (3) Use a reliability model that is statistically valid and accurately represents the system; (4) Account for the actual or predicted reliability of all subsystems and components; (5) Account for the effects of storage, transportation, handling, maintenance, and operating environments on component predicted reliability; and (6) Account for the interface between the launch vehicle systems and the flight termination system. (c) (1) Follow a standard industry methodology such as a fault tree analysis or a failure modes effects and criticality analysis; (2) Identify all possible failure modes and undesired events, their probability of occurrence, and their effects on system performance; (3) Identify single point failure modes; (4) Identify areas of design where redundancy is required and account for any failure mode where a component and its backup could fail at the same time due to a single cause; (5) Identify functions, including redundancy, which are not or cannot be tested; (6) Account for any potential system failures
