## Discrepancy

(CAN) AFTER TAKEOFF IN MINUS 42 DEGREES CENTIGRADE AND BLOWING SNOW, THE LANDING GEAR TOOK 3 CYCLE ATTEMPTS TO RETRACT.  SUBSEQUENT RETRACTIONS WERE NORMAL AS THE AIRCRAFT APPROACHED WARMER CLIMATES.  BEFORE LANDING AT HOME BASE, AND GEAR EXTENSION, A NOISE SIMILAR TO AN AIR LEAK WAS HEARD.  IT WAS DETERMINED THE THERMAL HYDRAULIC RELIEF VALVE WAS OPERATING AT A LOW PRESSURE.  VALVE WAS REPLACED.
