What constitutes an "emergency repair and overhaul" situation

Does anyone have any insight as to what exactly constitutes a bona fide "emergency repair and overhaul" situation regarding release/use of technical data marked with limited rights under the DFARS clause [252.227-7013](a)(14)?

The definition of limited rights in the DFARS allows release or use of limited rights technical data "Necessary for emergency repair and overhaul..." at 252.227-7013(a)(14)(i)(A), but it does not define what constitutes such - no criteria is given that I can see.
