I was a part of a crew along with NAME and NAME1 to downjack Aircraft X off jacks while trying to accomplish a landing gear health check. During the procedure the aircraft came off the nose jack; and caused puncture damaged to the lower forward belly skin. After further examination we realized we had failed to remove the tail stand. The aircraft tail stand did not have a safety alarm installed.The tail stands in the hangar used to have alarms installed on them. We might want to consider making sure we have the safety devices installed on all of our tail stands on company wide.
Technician reported that during down jacking; they neglected to remove the tail stand; resulting in damage to the forward fuselage skin.
