## Discrepancy

RECEIVED APU FIRE EXTINGUISHER FOR OVERHAUL AFTER FIRING.  DURING THE DISASSEMBLY, IT WAS DISCOVERED THAT THE PYROTECHNIC CARTRIDGE MELTED THE STAINLESS STEEL BOTTLE’S SEAT RENDERING THE PRESSURE VESSEL SCRAP.  THIS TYPE OF DAMAGE IS CONSISTENT WITH PREVIOUSLY REPORTED DAMAGE CAUSED BY THIS MFG CARTRIDGES.  REPAIR STATION IS VERY CONCERNED SINCE AT LEAST (2) OTHER UNRELATED REPAIR STATIONS HAVE REPORTED SIMILAR PROBLEMS WITH THE PYROTECHNIC CARTRIDGES FROM THIS MFG. (K)
