When researching a machinery expert witness, look for the expert who can provide analysis, reports, exhibits, and testing facilities. Eckstine & Associates, Inc., advises that the testing facility should be capable of conducting detailed experiments, performing accident reconstruction, conducting complete testing, and verifying failure analysis. Since trial exhibits and visual aids play an important part in contributing to the understanding of the facts of any case, look for CAD design and manufacturing of mock-ups and trial exhibits as well as conventional drawings, animations, displays, warning, charts and models.
