Search once.
Type the aircraft. Every authority answers in the same list, with status, dates and the link to the source.
Keep what applies.
Directives are matched to the exact model first, then the type family. Other families from the same maker stay out of the way.

- ModelThe AD names this exact model
- Type familySame family, another variant
- Make onlyThe AD names the manufacturer, no model
Another family from the same manufacturer is left out.
Record the decision.
Complied, recurring or not applicable, with the date, the method and a note. Every change goes to the aircraft's history.

2026-17-02 is in all 3. The FAA issued it and the other authorities adopted it under their own records. Checking one portal shows you one of them.
Everything after the search.
The search, as it is today
Make, model, authority and AD number, brand families grouped, and the official document one click from every row.

Watchlist alerts
Follow the makes and models you maintain. A new or revised AD that matches arrives by email.
Set up from the certificate
Upload the certificate of conformity. Zephr reads it and pre-fills make, model, serial, year and registration for you to confirm.
One directive, every authority's copy
Adopted ADs are linked across regulators, so FAA 2026-17-02 and its EASA and Transport Canada versions sit side by side.

Notes that stay with the AD
Rich notes on a directive or an aircraft, shared with your team by role or through a read-only public link.
A project per aircraft
Its applicable ADs, compliance history, folders and notes in one place, with overdue and recurring items first.
Exports for the audit
A PDF report an inspector can read, a CSV for your own systems, or the original authority PDFs in one zip.
Coverage you can count.

From each authority's official portal: FAA, EASA, Transport Canada, UK CAA, ANAC Brazil, ANAC Argentina and DGAC Chile. Every record links to the authority's own document.
Each portal is checked once a day. A new or revised directive normally appears within a day of the authority publishing it.
Add the makes and models you maintain to a watchlist. When a matching AD is published or revised, Zephr emails you.
They are on the roadmap. Enterprise customers can ask for an authority to be prioritised.
No. Zephr is a search and tracking layer over the official sources. Always confirm compliance against the authority's original document.
Pro is a single-user plan. Ultra includes 10 team seats. For more seats than that, ask us about Enterprise.
Your first search, in a minute.
