AINsight: FOD for Thought
Foreign objects can lead to serious aircraft incidents and accidents

The July 2022 crash of a CH-47D Chinook helicopter fighting a wildfire killed both pilots. “Specific damage to the iPad is likely tied to the cause of the crash,” said NTSB investigator Clint Johnson.

Foreign object debris (FOD) is a contributor to aircraft damage, serious incidents, and accidents in aviation. The problem is large and continues to grow. FAA reports suggest that FOD costs the U.S. aviation industry nearly $500 million annually; it is not only costly but can be deadly.

It is easy to see how the costs add up. Last year, a single misplaced flashlight caused $4 million in damage to the engine of a U.S. Air Force Lockheed F-35A. Following this mishap, an Air Force Times article stated that FOD was one factor that caused the number of ground accidents to nearly double from 2022 to 2023.
