STCs

by... CERTIFIED AERONAUTICAL PRODUCTS
"STC" stands for Supplemental Type Certificate.  This is the term for FAA approvals granted to a company or individual that authorizes a Major Alteration to a Type Certified airplane, engine, or propeller.  An STC can be authorized for "one-only" or "multiple" aircraft.  With permission from the STC holder, your A&P/IA may reference the STC as the approved data for the alteration.  No other approvals are necessary, unless you deviate from the STC drawings.
