Systems and methods are provided for a track roller failure detection system. The system may include a main aerodynamic device and a secondary aerodynamic device including a track supported by one or more rollers and a marker. Failure of the one or more rollers may result in the track contacting the marker. Operation of the secondary aerodynamic device when one or more of the rollers have failed may result in the marker leaving a mark and/or a trail on a portion of the main aerodynamic device and/or a portion of the secondary aerodynamic device. Failure of the one or more rollers may then be determined from the mark and/or trail.
