Ken Martin is an engineer with a multinational aerospace firm that produces a jet engine that is widely used by airplane manufacturers. Ken recently became aware of a potential defect in an engine part. As the lead engineer responsible for the part, Ken directed that tests be performed to ascertain the conditions under which the part might fail. The results of the tests indicate that at low temperatures a critical seal may crack, possibly allowing fluids to leak into other portions of the engine. Although the risks of such a leak are very low, the consequences are potentially disastrous.
