A shock absorber for an aircraft landing gear is disclosed. The shock absorber includes a stop surface arranged to limit extension of the shock absorber and a crumple element configured to deform in the event that the extension load on the stop surface exceeds a predetermined threshold. The crumple element may form part of the out-stop tube of the shock absorber. Deformation of the crumple element may be identified by measuring the length of the fully extending landing gear, through non-destructive testing or by measuring the change in conductance of the crumple element.
