Overview - ISO 16159:2025 (Space systems | Launch pad & integration site failure analysis)
ISO 16159:2025 establishes standardized procedures for investigating and analysing failures that occur during acceptance testing or operation of launch pad and integration site facilities, systems, and equipment. The standard defines processes to identify probable causes, determine the root cause, and develop corrective and preventive actions to prevent recurrence. It applies to launch pads and integration sites used for launches of launch vehicles with spacecraft for public and commercial purposes.
Key topics and technical requirements
- Failure analysis team composition: multidisciplinary teams including developer/manufacturer representatives, operators, component suppliers, maintenance, quality assurance and customer stakeholders. A safety representative must be included depending on test vs operation.
- Record evaluation: systematic review of design, production, normative documentation, acceptance test certificates, logs and service/manufacturing history for each involved component.
- Structured investigation process: information gathering (symptoms, time, environmental and power conditions, service life), site survey, documentation of operating parameters, and selection of relevant design and normative documents.
- Functional-track analysis: identify sequence of components transferring energy from the primary failed component to the discrepant component; examine failure preconditions and perform step‑by‑step disassembly where needed.
- Verification and measurement: measure component parameters, compare with documented requirements, record deviations and failure indications.
- Reporting and traceability: final failure analysis report must document findings, probable causes, laboratory analyses, recommended corrective and preventive actions, and determination of root cause. Reports are signed by the team; dissenting opinions may be attached.
- Corrective/preventive actions: procedures for defining, implementing and recording actions to preclude future failures (informative annex provides examples).
Practical applications
- Preventing recurrence of catastrophic failures that could damage flight or ground hardware and harm personnel.
- Standardising failure investigations across commercial spaceports, governmental launch facilities and integration sites to improve safety, reliability and knowledge transfer.
- Supporting post‑test and in‑operation incident response: clear steps for evidence collection, analysis, and documentation to inform maintenance, design changes and supplier corrective actions.
- Enabling consistent record-keeping to feed lessons-learned databases and accelerate root-cause resolution for future investigations.
