What type of mishap would be classified under a "Flight related" subcategory?

The classification of a mishap under the "Flight related" subcategory is based on the specific activities directly connected to flying operations. A mishap occurring during taxiing is directly associated with the operation of the aircraft while it is moving on the runway or taxiway, just prior to takeoff or after landing. This makes it a significant part of flight-related operations since it involves the aircraft in a flight context, albeit on the ground.

In contrast, mishaps that occur during maintenance pertain to ground operations that are not connected with the active flight of the aircraft. Similarly, incidents involving ground support vehicles occur while servicing or preparing the aircraft but do not involve the aircraft's actual flying activities. Finally, mishaps that are entirely unrelated to flight operations fall outside the scope of flight-related incidents, as they do not pertain to the aircraft's flight path or operational status. Thus, identifying a mishap during taxiing demonstrates a direct link to flight operations and confirms its classification as flight related.
