Facts: Engineer Intern A is an unlicensed engineer in the DOT's bridge inspection program under the supervision of Engineer B, a PE and state DOT director. While reviewing the inspection report for a bridge, Engineer Intern A observed that an inspector under the supervision of Engineer Intern A had failed to report a visibly obvious defect in a concrete bridge member. Concerned, Engineer Intern A reviewed the inspector's reports and photographs going back five years and discovered that the same inspector had failed to report the same defect for at least five years. Engineer Intern A reported the defect to Engineer B but did not report the fact that the defect had been visibly obvious for at least five years. Question(s): 1. Was it ethical for Engineer Intern A to fail to report to Engineer B that the defect had been missed for at least five annual inspections? NB: write your answer on the basis of the NSPE code of ethics and mention which all rules, fundamental, and professional obligations are related to this problem and explain in your words
