Full Turn-Key STCs

Complete STC Services

Sterling Helicopter offers complete STC services on Part 23, 25, 27, and 29 aircraft. Our engineering capabilities reach far beyond customers’ expectations.  This includes the entire STC process, from application to certification.  We handle all the engineering and each piece in-between.  This includes designing, modeling, drawings, plans and reports, substantiation data, ground testing, flight testing, EMI testing, and post-STC issuance assistance.

Testing can be done at Sterling Helicopter, or we can travel to your facility.  Sterling also holds FAA – PMA so once your STC is complete, we can manufacture parts that support your STC for you.  If desired, these parts can also be shipped from us to you with an FAA 8130-3 tag.  We have extensive experience in working with ACOs all over the country on certification projects.  Let Sterling be your STC agent and deal with the FAA, so you don’t have to.

Sterling also manages foreign validations for its clients. If you have an FAA STC and would like an EASA STC, ANAC STC, or TCCA STC through validation we would be happy to assist.
