The important safety and quality control concepts in aviation and aerospace sectors are FOD; foreign object damage. The damage caused by foreign debris affects the functionality, quality, and economic value of any aircraft or airplane. The FOD can be tools, scrap metals, building materials, trash, food wrappers, nuts, rags, gloves, and many more. All these if located in inappropriate places can cause havoc. To control FOD, many foreign object damage prevention programs and products have been introduced. The programs mainly focus on four critical areas of training, maintenance, coordination, and inspection. These programs define the procedures that are required for eliminating FOD successfully. www.foreignobjectdamage.com
