Foreign Object Damage

Foreign object damage (FOD) is defined as any damage attributed to a foreign object that can be expressed in physical or economic terms, which may or may not degrade the product’s required safety and/or performance characteristics. Some examples of how a foreign object causes damage include ingestion of loose hardware by an aircraft engine or passing debris through wind tunnel blades, short circuiting of flight electronics, contamination of sensors and optics, mechanisms that fail to operate properly and chemical attack on the physical properties of materials.
