The Importance of an STC in Aviation

August 9, 2016 | Author: Jeremy Dingman

According to the FAA, a supplemental type certificate (STC) is “a type certificate issued when an applicant has received FAA approval to modify an aeronautical product from its original design.”

However, for those who’ve never worked on an aircraft or know the requirements needed to work on an aircraft, this definition doesn’t explain how important an STC is to original equipment manufacturers (OEMs) and aftermarket service centers all around the world. Without an STC, companies that build or modify aircraft wouldn’t be able to make the improvements necessary to keep the planes we fly compliant with the upcoming mandates.

From airlines to business jets, Honeywell is committed to keeping OEMs and aftermarket service centers ready for upcoming mandates and the upgrades necessary to operate your aircraft for years to come.

Here is a list of some of our most recent STCs in 2016, available to the Honeywell dealer network:
