MRO software the regulator can actually read.

AMRO Pro is built for regional carriers and MRO operators who can't afford a seven-figure SAP rollout — but can't afford a missed inspection either. FAA, EASA, CAAC, and SACAA workflows are first-class, not bolted on.

What's inside AMRO Pro

Eight modules that connect a maintenance manual to a regulator-ready record.

MPD Tracking

planning

Maintenance Planning Document as a first-class data model, not a PDF

  • • Tasks, intervals, applicability rules stored as structured data
  • • Revision diff between MPD versions in one screen
  • • Applicability filters by aircraft type, serial, fleet, registration
Read more →

Work Orders

execution

Task-level sign-off — every step traceable to a named technician

  • • Task-level sign-off with named technician and license-category check
  • • Auto-linked to the MPD task and revision that authorized the work
  • • Findings + corrective actions captured as structured data

Parts Traceability

inventory

Chain-of-custody from PO to installation, airworthiness intact

  • • Serial-numbered rotables treated as first-class entities, not Excel rows
  • • 8130-3 / EASA Form 1 / CAAC AAC-038 attached to receipt records
  • • Movement history (PO → bond → shelf → install → removal) preserved forever

Multi-Regulator Workflows

compliance

FAA, EASA, CAAC, SACAA — first-class, not bolted on

  • • Authority-aware sign-off chains — B1, B2, C category mapping per authority
  • • Authority-specific form templates (8130-3, EASA Form 1, CAAC AAC-038, etc.)
  • • Per-authority deadline rules baked in (AD compliance windows, reporting cadence)
Read more →

Airworthiness Directives

compliance

AD compliance without a spreadsheet of doom

  • • AD library ingested from FAA / EASA / CAAC / SACAA bulletins
  • • Per-aircraft applicability evaluated against fleet master data
  • • Compliance status tracked through linked work orders
Read more →

Task Templates

execution

Reusable check sequences, version-controlled per fleet

  • • Build templates from MPD tasks or custom checklists
  • • Per-fleet, per-aircraft-type, per-operator template scoping
  • • Version every template — applied checks reference the template version they used
Read more →

Fleet Master Data

platform

One source of truth for aircraft, fleet hierarchy, locations, technicians

  • • Aircraft master with registration, MSN, fleet, base, regulator
  • • Fleet groupings for MPD scoping and reporting roll-ups
  • • Location hierarchy (line / hangar / base) for movement tracking
Read more →

Audit & Evidence Exports

compliance

Hand the inspector a folder, not a war story

  • • Pre-built export bundles per authority (FAA, EASA, CAAC, SACAA)
  • • Bundle scoped by aircraft, date range, AD set, or arbitrary query
  • • Each export includes a chain-of-custody document for every artifact

Why AMRO Pro instead of a 1990s MRO suite

Built for four regulators from day one
FAA, EASA, CAAC, SACAA. Not "FAA with a translation layer." Authority-aware forms, deadlines, sign-off chains.
Provenance, not paperwork
Every task signed off has a digital chain — who, when, against which MPD revision, against which AD. Inspectors get evidence, not stapled binders.
Multi-tenant, multi-MRO
Independent MROs serving multiple operators share a platform without sharing data. Each operator's records are their own.
Parts traceability that holds up
Chain-of-custody from purchase order to installation, with airworthiness tags preserved. No more spreadsheets-of-truth that crumble during an audit.
Modern engineering
Express microservice, React frontend, Postgres with RLS. The same stack powering modern SaaS — applied to a field that's been stuck on Oracle Forms.
No license-by-airframe pricing
Per-tenant SaaS pricing. Add an aircraft, the math doesn't break. Add a regulator, the platform doesn't need a re-implementation.

Pricing

Per-tenant, transparent, soon.

AMRO Pro is in closed pilot with regional carriers and independent MROs. Pricing tiers will publish here once we've validated them against real fleet sizes.

MRO

When an MRO outgrows spreadsheets

The specific failure modes that arrive when work orders, parts, and airworthiness records all live in Excel. Why the next step usually isn't SAP.
