Aircraft Collision

A light aircraft was destroyed in a mid-air collision with a jet trainer. APTECH was retained by the insurance carrier of the light airplane to reconstruct the accident. We obtained the remnants of the airplane and reassembled them in our laboratory. Measurements of the metal deformation, followed by stress and fracture mechanics analyses, enabled us to identify an impact point on the fuselage of the light plane.
