## Discrepancy

DURING RECERTIFICATION OF THE COPILOT'S STATIC SYSTEM (FAR 91.411), A 1350 FPM LEAK WAS NOTED AT 25,000 FEET.  TROUBLESHOOTING REVEALED THAT ALL FOUR FLEXIBLE STATIC LINES WERE LEAKING.  THE HOSES CURE DATE IS 2Q95.  THE HOSES WERE STIFF AND BRITTLE.  REPLACEMENT HOSES FROM CESSNA HAVE A 4Q96 CURE DATE AND ARE SOFT AND PLIABLE.  NO LEAKS WERE NOTED AFTER REPLACEMENT OF HOSES.
