## Analysis

THE PLT WAS LANDING ON A 2300 FT RWY WITH A 80 DEGREE X-WIND. THE ACFT BOUNCED HARD ON TOUCHDOWN AND THE PLT ATTEMPTED A GO-AROUND WITH 25 DEGREES OF FLAPS EXTENDED. THE AIRSPEED WAS DETERIORATING SO THE PLT ELECTED TO RE-LAND. DURING THE ROLL-OUT THE ACFT RAN OFF THE END OF THE RWY AND COLLIDED WITH THE EMBANKMENT OF A CREEK.
