The oscillations of the closed circular cylinder shell with a crack on the outside surface of shell are considered. The shape of the shell oscillations is picked out depended on orientation and place of a crack position on the shell. The crack «breathes»: it is supposed, that during oscillations the influence of the crack is exhibited only in one of the semicycles of the oscillation period. The parameters of the shell oscillations are changed during this time interval. It is allowed to carry out the diagnostics.
