## Discrepancy

(CAN) AT 10,000 FEET THE STANDBY ALTIMETER WAS READING 400 FEET LOW.  INVESTIGATION FOUND THE STANDBY STATIC LINE DRAIN LINE FULL OF WATER.  THE LINE WAS FOUND SPLIT & THUS LEAKING, OPEN TO CABIN PRESSURE.  THE SPLIT IN THE LINE IS CONSISTENT WITH DAMAGE CAUSED BY WATER FREEZING IN THE LINE.  THE LINE PN 83410474-001, AIPC 34-11-00, FIG 10-340 WAS REPLACED & THE STANDBY STATIC LINES PURGED & LEAK CHECKED.  A PREVIOUS SDR 20150106001 WAS SUBMITTED FOR THE SAME ISSUE ON A DIFFERENT TAIL.
