Structural Integrity Engineering
Structural Integrity Engineering, Inc. (SIE), was formed in 1981 to provide engineering, project development and technical consulting services to the aerospace industry. SIE is headquartered in Chatsworth California (30 miles north of Los Angeles) and also has branch offices in Seattle (Mukilteo, Washington near Boeing) and Madrid, Spain. SIE has a staff of 50 professionals consisting of certification engineers, aircraft designers and aircraft technicians. Five of the company’s engineers are FAA Designated Engineering Representatives (FAA DER) who have authority to approve reports and drawings for the FAA.
With the exception of the prime airframe OEM’s, SIE has performed more damage tolerance analysis for commercial aircraft than any other organization in the country.
The Art of Aerospace Engineering
SIE maintains a stable work force through its business model that includes a mix of outside consulting work and “in-house” projects. Aircraft design and certification is the company’s “core” business.

A Stable and Growing Staff
Over the last 30 years, the principals have specialized in aircraft research and development programs involving advanced design, structural analysis and certification. These design and analytical capabilities also include fatigue and damage tolerance considerations associated with aging aircraft. SIE is widely recognized by the FAA, and the aircraft industry-at-large as a leading expert in the areas of structural substantiation, fracture mechanics, fatigue and damage tolerance analysis and certification, as well as aircraft cargo conversions.
