Aero Design Services provides major alteration approvals. These approvals can be in the form of Supplemental Type Certificate (STC) or Major Alteration (8110-3). Most cabin modifications can be approved as a Major Alteration, which significantly cuts down on the time for approval from the FAA when compared to an STC approval. The type of approval depends on the customer needs and scope of the project.
Aero Design Services holds numerous FAA Supplemental Type Certificates and hundreds of FAA major alterations approvals for multiple aircraft types, covering all aspects of aircraft interiors. We had also provided certification support to for other STC holders.
