Safety-critical system design, test, and documentation.

CFR · 2024-01-01 · US · Title 14

(a) (1) Highly reliable flight safety systems covered under § 450.145; or (2) Safety-critical systems for which an operator demonstrates through its flight hazard analysis that the likelihood of any hazardous condition specifically associated with the system that may cause death or serious injury to the public is extremely remote, pursuant to § 450.109(b)(3). (b) (c) (d) (1) Functionally demonstrate any safety-critical system, while exposed to its predicted operating environments with margin, is free of defects, free of integration and workmanship errors, and ready for operational use; or (2) Combine in-process controls and a quality assurance process to ensure functional capability of any safety-critical system during its service life. (e) (2) An operator must monitor the flight environments experienced by safety-critical system components to the extent necessary to— (i) Validate the predicted operating environments; and (ii) Assess the actual component life remaining or adjust any inspection period. (f) (1) A list and description of each safety-critical system; (2) Drawings and schematics for each safety-critical system; (3) A summary of the analysis to determine the predicted operating environments and duration to be applied to qualification and acceptance testing covering the service life of any safety-critical system; (4) A description of any method used to validate the predicted operating environments; (5) A description of any instrumentation or inspection processes to
