Every safety document, connected.

Your safety case lives across FMEAs, hazard analyses, fault trees, requirements, and V&V reports, and they don't always agree. Adducia connects them into one source-linked graph that you can question in plain language. It also reviews the whole program for gaps and contradictions between documents. Each finding links to the line it came from.

The problem

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

Before an engineer can assess a hazard or close a requirement, they must find the evidence. It is rarely 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 in spreadsheets, hazard logs, and fault-tree figures. A text search won't find it.

03 Every revision The same item gets new names and numbers across documents and baselines. Nothing lines up, and disagreements stay hidden until a review finds them.

What Adducia does

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

01 Reads your safety documents Reads FMEA and FMECA workbooks, FHAs, fault trees, reliability block diagrams, V&V matrices, and hazard logs. It also reads requirements exports from DOORS and Jama, tables and figures included.

02 Builds a connected graph Links each hazard to its causes, controls, requirements, and closing evidence. Joins the same item across documents into one. Asks you when two names may mean one thing.

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 Reviews it, and you decide An AI review finds unmitigated hazards, unverified requirements, and places where two documents disagree. Code checks that each quote it cites is in your document. No finding goes into a report until an engineer confirms it.

See it work

Ask in plain language. Verify in one glance.

Every answer comes with its evidence, the exact line from your document. The review also flags where your documents disagree, before an audit finds it.

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”

Must fixProposed

HL-001 is Catastrophic in the FHA but Hazardous in the SSA

Why it mattersThe lower class would let the engine control software carry a lower assurance level.

FHA rev A · p. 3Found in document

“HL-001 Loss of engine power in flight, classified Catastrophic.”

SSA rev A · p. 7Found in document

“HL-001 is assessed as Hazardous given the dual-channel control.”

Built for trust

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

Every ID validated Code checks every artifact an answer cites against the graph built from your documents. It flags a claim that disagrees with the graph's links. Adducia won't invent a requirement, a standard, or an artifact number.

Honest about its limits When your documents can't support an answer, it says so. It doesn't guess. A confident wrong answer is the most dangerous thing a safety tool can produce.

Your documents stay yours Pilots run on your own documents, under NDA, in a private workspace. Export-controlled or classified material never comes to us. For that, Adducia runs in your own cloud tenant or on your own hardware. There is no telemetry, and nothing is used to train models.

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

Send one document. See what the review finds.

We're working with a small number of safety and certification teams. Send us one safety document under NDA before a 30-minute call. We run Adducia on it before the call. On the call, we walk you through the findings, and you keep them. No setup on your side.
