## Discrepancy

DURING SERVICE CHECKS, TECHNICIAN NOTICED LANDING GEAR EMERGENCY EXTENSION BOTTLE GAUGE READING ZERO.  UPON SERVICING, NOTICED THE NITROGEN WAS NOT FILLING AND IMMEDIATELY LEAKING OUT.  FURTHER TROUBLESHOOTING REVEALED THE UNION THAT SCREWS INTO THE BOTTLE HAD SHEARED OFF.  NO AIRCRAFT DAMAGE FROM THE HIGH PRESSURE UNION SHEARING, BUT HAD THERE BEEN A GEAR ISSUE ON THE PREVIOUS FLIGHT, THE EMERGENCY SYSTEM WOULD NOT HAVE WORKED.  UNIT WAS HYDROSTATIC TESTED 10/2020.
