Find any part.
And who else makes it.

Search across every part number.
Instant search across part names, numbers, and manufacturers. Filter by ATA chapter-section-subject. Find the exact component you need across every catalog in the library.

- A PMA count on every result, straight from the FAA
See where every part fits.
Every part gets a graph: the assemblies it goes into above (Next Higher Assembly), the parts it contains below (Next Lower Assemblies). Merged across every manual at once, so a bearing used in six assemblies is six nodes on one screen — not six documents on your desk.
- Merged across manuals, with a per-node manual count
- Click any node to walk to that part
- Understand the full bill of materials at a glance
Every node links to its own part page.

Pricing is available from each holder directly. Confirm approval and applicability with the PMA holder before ordering.
Know every approved alternative.
The FAA publishes a Parts Manufacturer Approval database, but it is a monthly bulk dump keyed on free-text part references, not something you can search. BOMtrail PRT resolves it against the catalog and puts the answer on the part.
- Every holder, their own part number, and the FAA approval
- One company, one entry — acquisitions and renames merged
- Who appears is FAA data, never a paid placement
