Aerospace safety & reliability intelligence

Catch the gap before the audit does.

Your safety case lives across FMEAs, hazard analyses, fault trees, requirements, and V&V reports that don't always agree. Adducia connects them into one source-linked graph you can question in plain language, and deterministically checks the whole corpus for the gaps and contradictions hiding between documents.

The problem

The analysis isn't the slow part. Finding the inputs is.

Before an engineer can assess a hazard or close a requirement, the underlying evidence has to be found, and it rarely lives in one place.

01 Many documents Hazards, causes, controls, and evidence are split across FMEAs, FHAs, fault trees, requirements, and V&V reports. A single component's analysis can run past two hundred pages.

02 Tables & diagrams The information you need is locked inside spreadsheets, hazard logs, and fault-tree figures, not searchable prose.

03 Every revision The same artifact is renamed and renumbered across documents and program baselines, so nothing lines up, and the disagreements hide until a review finds them.

What Adducia does

One connected, source-linked picture of your safety library.

01 Reads your safety documents Ingests FMEA and FMECA, FHA, fault trees, reliability block diagrams, requirements, V&V matrices, and hazard logs, including the tables and figures.

02 Builds a connected graph Links hazards to their causes, controls, requirements, and closing evidence, and resolves the same artifact across documents into a single node.

03 Answers in plain language Ask a question the way you would ask a colleague. Every answer cites the exact document and location it came from, so you can verify it.

04 Checks it against itself Deterministic checks surface unmitigated hazards, unverified requirements, and places where two documents disagree about the same item. Computed from the graph, never generated, so a finding can't be invented.

See it work

Ask in plain language. Verify in one glance.

Every answer arrives with its evidence, each artifact carrying the exact verbatim line from your document. And the assurance check flags where the documents disagree with each other, before a review finds it for you.

ASKWhich failure modes are the most severe, and what controls exist for them?

Eight failure modes are rated Catastrophic. Each one's compensating control is listed below, with the source row behind it.

Failure ModeInternal short circuit (LP-CELL-01)FMECA · R1

“Failure Mode: Internal short circuit”

ControlInter-cell thermal barrier; BMS protectionFMECA · R1

“Compensating Provision: Inter-cell thermal barrier; BMS cell protection”

Failure ModeFails to detect isolation loss (LP-IMU-05)FMECA · R7

“Failure Mode: Fails to detect isolation loss”

Built for trust

An answer you can't trace is worthless in a safety review.

Every ID validated Every artifact ID and claim in an answer is checked against the graph built from your documents. It will not invent a requirement, a standard, or an artifact number.

Honest about its limits When it can't ground an answer in your documents, it says so instead of guessing. A confident wrong answer is the most dangerous thing a safety tool can produce.

Runs entirely in your environment An on-prem build installs on your own hardware and calls the model with your own key. Nothing is sent to us, and there is no telemetry.

Who it's for

For the people who own the safety case.

01 Safety engineers Trace any hazard to its causes, controls, and the requirement that mitigates it, without opening ten documents.

02 Reliability & RAMS Pull failure modes, rates, and redundancy structure across the program, and see everything a single component touches.

03 Certification & DER Answer "show me the source" instantly, and surface coverage gaps before a review does.

Next step

Bring one document. Leave with the findings.

We're working with a small number of safety and certification teams. Bring one sanitized or public safety document to a 30-minute call. We run Adducia on it live while you watch, and you keep the findings. No setup on your side.
