## Analysis

DURING A DUAL INSTRUCTIONAL FLT, THE INSTRUCTOR PLT (CFI) RETARDED THE THROTTLE TO SIMULATE A FORCED LANDING. HE STATED THAT THE STUDENT DID THE EMERGENCY PROCEDURE & HEADED FOR THE FIELD. LATER, WHEN THE THROTTLE WAS ADVANCED, THE ENG DID NOT RESPOND. THE CFI ASSUMED CONTROL OF THE ACFT & TRIED TO RESTART THE ENG 3 TIMES, BUT IT WOULD NOT RESPOND. HE THEN ATTEMPTED TO MAKE AN ACTUAL FORCED LANDING IN AN OPEN FIELD, BUT WAS UNABLE TO CLEAR OVER A FENCE. THE LANDING GEAR & LEFT WING HIT THE FENCE & THE ACFT PITCHED DOWN, NOSE 1ST & WAS DAMAGED. LATER, THE ENG WAS OPERATED WITH NO INDICATION FOR A LOSS OF POWER.
