This AD was prompted by reports of the electrical connectors for the fire bottles in the forward and aft compartments being cross connected. The FAA is issuing this AD to detect and correct cross connection of the fire extinguisher bottles, which could result in failure of the fire bottles to discharge and consequent inability to extinguish a fire in the affected areas.
