A forensic case involved an allegation of defective minivan brake repairs. On a wet two-lane road, the minivan left the road while stopping, and impacted a telephone pole. The plaintiff driver’s complaints implied a dragging brake, and the plaintiff ’s expert reported a bent lower caliper bolt. This forensic investigation involved instrumented exemplar analysis of the effects on caliper drag that could be caused by a bent caliper bolt. The investigation methodology was chosen (in part) based on significant evidence spoliation on the part of the plaintiff ’s expert. This paper will also discuss the effects of the spoliation and resulting limitations on the scope of the analysis.

The Approach To Forensic Investigation Of A Medical Device Related Accident Differs From That For Consumer Products, Industrial Equipment, And Vehicles. Techniques For Investigating And Providing Case Assistance Related To Suspected Medical Device Incidents Are Presented, Including Essential Elements Of The Investigation, Investigative Techniques, And Information Resources On Device Failures And Standards. User Error Versus Design Defect Is Discussed, Along With The Causes Of Medical Device-Related Incident And The Mechanisms By Which They Cause Injury And Death. Since A Patient Is A Variable Biological System, It Must Also Be Considered That The Alleged Cause Of The Incident Was Not Attributable To The Medical Device.

Non Destructive Techniques

CANDU reactors use Zr-2.5 Nb alloy pressure tubes, as the primary pressure boundary within the reactor core. These components are subject to periodic inspection and material surveillance programs. Occasionally, the inspection program uncovers a flaw, whereupon the flaw is assessed as to whether it compromises the integrity of the pressure-retaining component. In 1998, such a flaw was observed in one pressure tube of a reactor. Non-destructive techniques and analysis were used to form a basis to disposition the flaw, and the component was fit for a limited service life. This component was eventually removed from service, whereupon the destructive examinations were used to validate the disposition assumptions used. Such a process of validation provides credibility to the disposition process. This paper reviews the original flaw and its subsequent destructive evaluation.
