Search the public FAA STC directory

Search by STC number, holder, aircraft manufacturer or model, modification, or category.

You can also search explicitly by type certificate (TC) number and filter current, withdrawn, superseded, or historical records. Status refers to the cited source, not commercial availability.

The search index loads only when you focus or type in this field.
