Narrative:

I was the student in the left seat. We were practicing single engine lndgs in the pattern. On downwind the instrument simulated a left engine failure. After finishing engine failure procedures I performed a gumps check and checked for 3 in the green as I turned base to final. Upon T/D we realized the gear had not lowered. We slid about 350' before stopping. All passenger vacated the aircraft unharmed. The aircraft had damage to the propellers and bottom of the fuselage.
