Abstract:  
History proves that there are severe consequences for poor shot peening practices in the aerospace industry. In the spring of 1992, three men were sentenced to jail time in a bad-parts case. The case, involving three brothers who ran a family business, St. Charles Metal Finishing Co. in St. Louis, Missouri, set off tremors in the passenger aircraft industry when companies learned that their planes might be flying on untested parts. St. Charles Metal Finishing provided shot peening, blast cleaning and structural testing services to the aerospace industry. The three executives falsified inspection reports for parts used on 1,000 fighter planes built by McDonnell Douglas Corp.
