THE AIRCRAFT'S LANDING GEAR COLLAPSED AFTER THE PLANE WENT OFF THE RIGHT SIDE OF RUNWAY 23 DURING TAKEOFF. REPORTEDLY, THE AIRCRAFT DRIFTED TO THE RIGHT OF CENTERLINE ON A FAIRLY CONSTANT ARC UNTIL CONTACTING A SNOW BERM AT A TAXIWAY INTERSECTION. AN INVESTIGATION REVEALED THAT THE TAKEOFF WAS BEING CONDUCTED AT NIGHT WITH A PARTIALLY OBSCURED WINDSHIELD. VISIBILITY WAS ONE MILE WITH FOG AND FALLING SNOW, AND THE WIND WAS FROM 150 DEGREES AT 11 KNOTS. THE RUNWAY WAS COVERED WITH ABOUT 1/4 INCH OF SNOW. THE COPILOT'S DUTIES REQUIRED HIM TO SCAN 'INSIDE' THE COCKPIT, WHILE HE 'FINE TUNED' THE POWER SETTINGS AND CHECKED ENGINE INSTRUMENTS DURING THE TAKEOFF ROLL. NO PRE-ACCIDENT PART FAILURE OR MALFUNCTION OF THE AIRCRAFT WAS FOUND DURING THE INVESTIGATION.
