Airworth Hangar — the airworthiness portal for the aircraft you maintain.

Hangar tracks the four documents Part-ML expects you to keep current, against the actual flight hours you log. ADs, SBs, component times, ARC. EASA and FAA, both regimes, in one view.

AD and SB tracking by tail number

Hangar ships with a 727-entry catalog of service documents — Airworthiness Directives and Service Bulletins — with an applicability engine that matches each document against your aircraft’s serial range, model, date of manufacture, and installed equipment. You don’t get a wall of every Lycoming AD ever issued; you get the ones that actually apply to your tail.

The catalog is updated monthly via a Cowork workflow. New documents get surfaced in your Today feed with a drill-down view and an opt-in digest email.

What this means in practice: when EASA AD 2024-XXXX drops on PA-28 fuel selectors, if you fly a PA-28-181 with the affected serial range, you see it. If you don’t, you don’t. Recurring vs one-time. Date-based vs landing-based. The engine knows the difference.

Component times that update with every flight

Maintenance triggers in Hangar work three ways: hour-based, calendar-based, and cycle-based at aircraft level. Every time you log flight hours, components recompute. The dashboard surfaces overdue, critical, upcoming, and OK as a categorised list. Per-aircraft YES/NO airworthiness verdict at the top.

Quick-log flight hours from the dashboard. Component CRUD with serial number, life limit, install date. TBO countdown and remaining hours per component. When you record a maintenance compliance, next-due recalculates automatically — math consolidated in one service so the dashboard and the work order agree.

(Cycle tracking today is at aircraft level, not per-component. We say so on the page rather than letting you discover it later.)

Part-ML and FAR Part 91 in one view

Each aircraft carries a regulatory framework — EASA Part-ML, FAR Part 91, or a per-aircraft override. The dashboard, the inspection signoffs, and the recordkeeping templates change accordingly.

If you fly an N-registered Cirrus in Europe, Hangar doesn’t make you choose a side. If your shared ownership group has both an EASA Cessna and an FAA Beech, both live in the same account with the right framework rules.

Read the Part-ML compliance guide for the regulatory background, and EASA vs FAA maintenance recordkeeping for the side-by-side reference.

Imports your aircraft logbook PDF

Hangar parses your aircraft logbook PDF in two tiers: text extraction first, then a vision fallback for scanned or photographed pages. The parser pulls flight times, dates, and tail numbers; you confirm before anything is written into the ledger.

The flight log itself supports thirteen importer formats and five input modes (manual entry, paste, drop a file, PWA share-target from your phone, OCR-from-photo). Multi-pilot. Ghost-flight reconstruction for missing entries. Electronic CFI signing. PDF export with a hash-chain that lets a future inspector confirm the file wasn’t tampered with after the fact.

(One caveat we’ll be honest about: the hash-chain verification has a known edge case for aircraft logged before our PR #51. New aircraft are fine; legacy data has a fix in flight.)

ARC renewal timeline

The 90-day window before expiry is when you need to be moving. Hangar surfaces it on the dashboard as a date, not as a generic “review your aircraft.” Documents the inspector typically requests live in the document vault — including ARC slots, with the right doc-type taxonomy.

The full step-by-step, including CAMO/CAO vs Part-ML self-managed, lives in the ARC renewal checklist.

Multi-user with role-based access (when shipped)

For shared ownership groups, Hangar today supports inviting a co-owner to a single aircraft (early access). Full multi-user role-based access — airworthiness lead, treasurer, members, with read/write scopes per role — is coming soon, not yet shipped. We list this honestly because pilots cross-check.

If you run a flying club or shared-ownership group, see the dedicated for clubs page and the guide on aircraft document organization for shared ownership.

What’s also in the box

A non-exhaustive list of things that ship today and matter to owner-pilots:

• Cost Ledger — manual + AI-categorised expense entry, receipt extraction, bank CSV import with FX, work-order cost-line auto-post, per-component reserve accrual, multi-currency, VAT, capex/opex, dashboard cost tile.
• Aircraft-level insurance records — policy fields and certificate PDF in the document vault, fields auto-populated from upload. Record-keeping only; we are not a broker.
• Shop portal at shop.airworth.app — magic-link, multi-format findings upload, completed-task collapse, per-token rate limiting, shop↔owner messaging, e-signature, immutable audit chain, Resend email, printable work-order template.
• Oil tendency analytics — anomaly detection on your oil samples with a plain-English health summary.
• Global ⌘K search with offline trigram index.
• Light/dark/system theme toggle.
• Print views for work order, inspection, maintenance task list, compliance snapshot, AD/SB/SL applicability report, and logbook pages — six surfaces.
• GDPR self-service export and delete, two-stage with 30-day recovery.
• API rate limiting, server-side schema validation, Sentry observability.
• Offline-first PWA — installable, works in the hangar without signal.

(Some forms still require connectivity to write through; a write-surface coverage audit is in our backlog. We say “offline-capable PWA,” not “every form works offline.”)

Pair with the planner

Sign in to Airworth Flights with your Airworth account. The OAuth federation is live today. Deeper data sync — pulling aircraft hours-remaining into your trip briefing card; pushing flights from Flights into the Hangar logbook — is in early access; some surfaces are committed for the next three months and we will not pretend they ship today.

Pricing during early access

Free during early access. We are not promising “always free,” and we are not collecting payment information today. Pricing models are an open question and will be communicated before anyone is charged.

FAQ

Does Hangar work with my aircraft? If it’s a piston single, very likely. Eight templates ship today (C172S, C182T, PA-28-181, SR22 G6, DA40 NG, DA42 VI, A36, TB20) plus fully custom configurations. Templates carry a regulatory framework column.

Do you support UK CAA? Not yet. EASA and FAA today; UK CAA is on the backlog.

Do you handle MEL? No. MEL handling is not on the roadmap.

Can multiple co-owners access the same aircraft? Single-owner with shared-aircraft co-owner invite works today, in early access. Several read-paths for shared data are still being closed (oil samples, expenses, documents). Full co-ownership parity is coming, not shipped. See the shared-ownership document guide.

Does Hangar send reminder emails for ARC, insurance, annual? Not yet. Today the ARC clock surfaces in the dashboard. Email and push notifications for these reminders are deferred. Don’t rely on Hangar for them.
