THE INSTRUCTOR PLT (CFI) HAD SIMULATED A LOSS OF PWR IN THE RGT ENG & THE STUDENT WAS MAKING AN APCH. THE CFI THEN PULLED THE CIRCUIT BREAKER (CB) FOR THE NORMAL GEAR EXTENTION SYS. THE STUDENT TRIED TO EXTEND THE GEAR WITH THE ALTN SYS, BUT THE LEFT GEAR DID NOT LOCK DOWN. THE CFI PUT THE CB BACK IN & RECYCLED THE GEAR, BUT THE LEFT GEAR STILL DID NOT SHOW DOWN & LOCKED. THE CFI THEN ORDERED A GO-AROUND. THE GO-AROUND WAS INITIATED AT ABOUT 300 FT AGL. WHEN THE THROTTLES WERE ADVANCED, THE CFI NOTED A LACK OF PWR IN THE RGT ENG & TOOK CONTROL OF THE ACFT. HE TRIED TO RESTORE FULL PWR TO THE RGT ENG, WHICH HE PERCEIVED WAS PRODUCING SOME PWR. THE PROP WASN'T FEATHERED. IN THAT CONFIGURATION, THE ACFT MAINTAINED LEVEL FLT, BUT WOULD NOT CLIMB. SUBSEQUENTLY, IT BEGAN TO DESCEND & THE CFI MADE A FORCED LANDING ON ROUGH DESERT TERRAIN. NO REASON FOR THE RPRTD LOSS OF ENG POWER WAS FOUND DRG A SUBSEQUENT INVESTIGATION.
