## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) WHILE PERFORMING COMMERCIAL MANEUVERS IN THE SIMI VALLEY PRACTICE AREA ON A DUAL LESSON CREW DESCENDED FROM 3500 FT TO ABOUT 1000 FT TO PERFORM EIGHTS ON PYLONS.  WHEN THE STUDENT PILOT APPLIED POWER TO LEAVE OFF, THE THROTTLE OFFERED NO RESISTANCE AND HAD NO EFFECT ON THE ENGINE'S POWER OUTPUT.  STUDENT PILOT LOWERED THE GEAR AND THE FLAPS, ENTERED A FULL SLIP AIMED THE PLANE AT THE FIELD.  AT APPROXIMATELY 500 FEET THE FLIGHT INSTRUCTOR TOOK CONTROL AND CONTINUED THE SLIP TOWARDS THE FIELD.  THE INSTRUCTOR ATTEMPTED TO LAND IN THE FIELD BUT OVERSHOT THE FIELD AND WAS FORCED TO CRASH THE PLANE UP THE SIDE OF A HILL.  THE NOSE WHEEL CAUGHT A RIDGE AS IT IMPACTED THE HILL AND WAS TORN OFF.  THE IMPACT ALSO CAUSED THE AIRCRAFT TO BE FLIPPED OVER.
