LoftWright reads your STC modification drawings and generates installation instructions, ICA, and the master data list — every value traced to its source, every step ready for your DER.
Every STC requires Instructions for Continued Airworthiness. Most design organizations still produce them the same way they did in 1985 — manually, in Word, from a drawing package spread across a shared drive.
A single STC modification package — installation instructions, ICA, master data list — can take a senior engineer three to six weeks to produce correctly. That time could be engineering hours on the next program.
When a drawing revises, the installation instructions, the ICA, and the master data list all need updating — manually, in parallel, with no automated link between the drawing and any of them. Mismatches are a leading source of certification findings.
The Airworthiness Limitations Section is separately approvable and mandatory. An interval error doesn't just create a finding — it propagates into operator maintenance programs. It's the highest-consequence output of the authoring process and still the least supported by tooling.
The engine reads your drawing package, extracts every entity with traceable attribution, enforces airworthiness rules, and assembles certified-ready output — without generating a single safety-critical value from a language model.
2D vector PDFs, DXF, STEP AP242 model-based definition, native CAD, or legacy scanned drawings. The engine accepts the full range of formats found in real STC packages.
Title blocks, BOMs, dimensions, GD&T, notes, materials, fasteners, zones, and effectivity — extracted as structured, confidence-scored entities, each referenced back to its source position in the drawing.
Installation instructions, ICA structured to 14 CFR Appendix H, and the master data list — routed to your engineering and quality review, then to your DER or ODA unit member for approval.
The certified data products an STC design organization must author and maintain — generated from the drawing package, not written from scratch.
Sequenced, zone-referenced steps to install the modification. Every part number, torque reference, and material callout traced directly to the drawing. Formatted for DER review and Part 145 installer use.
14 CFR 21.50Assembled to the 14 CFR Part 25 Appendix H content structure. Includes the Airworthiness Limitations Section as a protected, separately approvable element — intervals injected deterministically from substantiation, never generated.
25.1529 / App. HIndexed, revision-controlled list of all drawings and data in the package, maintained in sync with the drawing repository. Revision changes propagate automatically.
AML-awareTail-specific shop travelers derived from the approved installation instructions, formatted for the Part 145 repair station's MRO system — with effectivity resolved to the individual aircraft serial number.
Part 145 / MROLoftWright is the only drawing-to-tech-data platform designed around the civil airworthiness approval workflow — not bolted onto it afterward.
Torque values, dimensional tolerances, GD&T thresholds, and airworthiness-limitation intervals are extracted from the drawing and injected by a deterministic template engine. The language model never sees or emits them — making a transposed or fabricated value structurally impossible, not just unlikely.
The Airworthiness Limitations Section is generated as a segregated, separately approvable element and locked once approved. Any subsequent edit requires the certification approval path — the engine enforces this automatically.
Every instruction step, part callout, and value in a generated product links to the specific drawing, revision, and section it came from — reconstructable on demand for DER review or authority inspection.
Effectivity is managed as an Approved Model List. The builder resolves each product against the AML and per-model baseline configuration, generating model-specific supplements where access, structure, or prior modifications differ. Adding a model to an AML flags the required substantiation delta automatically.
Generated products route through a defined workflow — engineering review, quality review, then DER/ODA unit member or EASA DOA signatory. Digital signatures embed in the PDF and record to the audit ledger. LoftWright produces the data; the qualified signatory makes the compliance finding.
Every ingestion, extraction decision, rule evaluation, generation event, and approval action is logged to an append-only, cryptographically verified ledger. The complete provenance of any work product is available on demand.
LoftWright is designed for the organizations that hold STCs, author ICAs, and feel the authoring burden on every program.
You hold one or more STCs and your engineers author installation instructions and ICA manually for every modification and every revision. The drawing-to-certified-data gap is your core production bottleneck.
You install modifications under approved STC packages and produce tail-specific work cards or travelers for each aircraft. You need effectivity resolved to the individual serial number and the instruction formatted for your shop floor and MRO system.
High-volume, per-customer instruction sets from seat and interior drawings — the same drawing-to-work-instruction problem with added flammability and 16g dynamic-seat substantiation. Targeted in the next platform edition.
LoftWright is in development. We're looking for a small number of STC design organizations to participate in our pilot — bring a real modification drawing package and we'll run it through the engine together. If you hold STCs and author ICA manually, we'd like to hear from you.
We'll respond within two business days. No sales calls without your permission.
We'll be in touch within two business days to learn more about your modification programs and schedule a first conversation.
