Who we are

Aircraft Structures Engineering Solutions LLC is a family operated aerospace engineering service company specializing in the FAA/EASA approval of Part 23 and Part 25 aircraft, aircraft components and aircraft systems. We provide engineering support (Design, Analysis, and Testing) and FAA DER/ EASA CVE approvals to the aviation industry.

Structural design is our true passion. Having worked in the aerospace industry for over a decade, our engineers posses a great wealth of knowledge in design and analysis of complex repairs and alterations.

Design and Engineering

We combine classical analysis techniques with modern tools such as CAD and FEM softwares. Whether it’s a small GPS antenna Installation or a complex airplane fire fighter conversion, we can provide you with the necessary engineering support. To maintain the most up-to-date knowledge, our engineers regularly attend, FAA seminars, courses in specialized fields (Fatigue and Damage Tolerance) and MRO conferences. We considered ourselves to be specialists in Static, Fatigue and Damage Tolerance evaluations.

Project Management

Project management can be very complex and time consuming for large scale STC projects. Mismanaged project often results in unacceptable delays obtaining regulatory approvals. Our experienced project engineers can manage your project in an efficient way to avoid the hassles.


We can provide you the appropriate approvals for your certification needs.ASES has experience working directly with FAA, ODA (FAA) and DOA (EASA)

We use the following licensed engineering softwares for our analysis

Our library consists of most of the industry standard references including Bruhn, Niu, Allen and Haisler, Rivello, Orden and Boeing Design Manual. We use the following licensed engineering softwares for our analysis


FAA/EASA Certification

We can provide major repair and alteration data approvals for Owner/Operator under 14 CFR Part 43, or Certified Repair stations under 14 CFR Part 145.

Our certification projects for Part 23 and Part 25 airplanes can range from filed approvals (8110-3) to FAA design and modification approvals under 14 CFR Part 21 (STC and PMA). With the integrity and quality of work, our engineers have formed a trusted working relationship with the regulatory authorities. We work closely with FAA, EASA, ODAs and DOAs. Also, we are currently involved with the Transport Canada (TACA) and South African Civil Aviation Authority (SACAA). Our services includes,

  • FAA/EASA Complete Data Packages including Approvals (STC and Field Approvals)
  • Weight and Balance Reports
  • Flammability Assessment Reports
  • Mechanical System Safety Analysis
  • Certification Plans
  • Test Plans and Test Reports (Bird Strike/ dynamic Seat Testing/ Head Strike)
