These actions are intended to prevent high-velocity separation of a barrel, piston or end cap from a hydraulic accumulator. Such separation could result in injury to personnel, loss of cabin pressurisation, loss of affected hydraulic systems or damage to plumbing, electrical installations or structural members.
