Abstract
To monitor for the formation of a crack in a metal wheel such as that of an aircraft tire and wheel assembly the wheel is provided with an optical fiber arranged to extend no-rectilinearly in a position of the wheel surface selected to be preferential for the development of a crack; preferably the preferential region for crack development is the tire bead seat region and the optical fiber is arranged to extend non-rectilinearly around the circumference of the tire bead seat region thereby to lie interposed between the wheel and tire.
