## Analysis

DURING THE CLIMB FROM TAKEOFF, THE FRONT ENGINE SUSTAINED A TOTAL POWER LOSS DUE TO A FUEL LEAK. THE PILOT SECURED THE ENGINE, HOWEVER WAS UNABLE TO MAINTAIN ALTITUDE, LOSING ABOUT 50 FT PER MINUTE. DUE TO A THUNDERSTORM AT THE DEPARTURE AIRPORT, HE ELECTED TO CONDUCT AN EMERGENCY LANDING IN A FIELD. HE REPORTED DOWNDRAFTS AND WINDSHIFTS WHICH FORCED THE LANDING TO BE LONG. DURING ROLLOUT THE AIRCRAFT STRUCK AN EMBANKMENT.
