## Discrepancy

(CAN)THE CREW MADE AN UNEVENTFUL SHORT TURN AROUND AT DAWSON CREEK (-35C),THEN PROCEEDED TO FT.  ST.  JOHN (-41C).  DURING THE APP A LOUD BANG WAS HEARD DURING GEAR EXTENSION.  ALL ATTEMPTS TO LOWER THE GEAR WERE UNSUCCESSFUL.  THE ACFT MADE A SUCCESSFUL GEAR-UP LANDING ON AN ICE COVERED RUNWAY.  THERE WERE NO INJURIES & VERY LITTLE DAMAGE TO THE AIRCRAFT. INVEST FOUND THE GEAR DOORS TIGHT AGAINST THE MAIN TIRES.  THE GEAR WAS EXTENDED & THE NOSE STRUT FOUND FLAT.  SUBMITTER STATES THAT THE NOSE GEAR STRUT WENT FLAT ON TAKEOFF FROM DAWSON DUE TO THE COLD & A "CHAFED" 'O'RING.  THIS ALLOWED THE DOORS TO CLOSE APPROX.  95 PERCENT, EN OUGH TO SIGNAL GEAR-UP, BUT ALSO JAMMING THE GEAR IN THE UP POSITION.
