Every requirement.
Every link. Every status.

Aviation certification demands that every applicable regulation is acknowledged, assessed, and proven compliant. Without a systematic traceability matrix, engineering teams lose track, auditors find gaps, and certification programs slip.

TracePath gives you a structured, filterable, exportable matrix that maps your aircraft systems against EASA CS-25 and CS-23 paragraphs — with means of compliance and progress tracking

CS-25 (EASA) CS-23 (EASA)
Workflow Utility: TracePath is not an officially certified EASA or FAA tool, but a supporting workflow tool designed for solo engineers and small teams to clearly track and organize requirements and compliance tasks.

Live Compliance Status

Track each requirement as Open, In Progress, Compliant, or N/A. See your compliance rate update in real time across subparts and systems. Know exactly where you stand at any moment.

4 status levels

Means of Compliance

Assign the correct MoC — Analysis, Test, Simulation, Inspection, Design Review, Similarity, Service Experience, or Engineering Judgement — directly on each requirement.

8 MoC types

CSV Import & Export

Import existing compliance data from spreadsheets in seconds. Export your complete traceability matrix as a clean, structured CSV.

Audit-ready output

Powerful Filtering

Filter by regulation, subpart, system, subsystem, status, or means of compliance simultaneously. Full-text search across paragraph IDs, titles, and notes. Find anything instantly.

Multi-filter

100% Local JSON Projects

No database required for single users. Your sensitive engineering data is stored locally in clean JSON project files. 100% GDPR/data privacy compliant, securely residing entirely on your machine.

No Cloud or DB Required

From blank matrix to certified in three steps

Designed around the actual certification workflow — not the other way around.

01

Load Your Requirements

Identify the applicable regulations for your program — EASA CS-25 or CS-23 — using the pre-loaded library as a reference, and enter your paragraphs. Or import your existing requirement CSV from Excel.

02

Map & Track Compliance

Assign each requirement to a system, set the means of compliance, and update status as your program advances. Add notes for open items, responsible engineers, and reference documents.

03

Export & Submit

When your compliance rate reaches 100%, export the complete traceability matrix as a structured CSV.
