Narrative:

During mei training at ZZZ; I wanted to have the mei student evaluate and critique my precautionary engine shutdown and simulated single engine traffic pattern/approach/landing. The right engine throttle was set to simulated feather and the left engine throttle was set to maintain a normal traffic pattern approach to land. While I was playing 'student' I intentionally did not put the flaps in for landing to see if the student would correct my error. On final for runway 9; the student made me aware that the flaps were not extended; so I lowered them to the prescribed 25 degrees. We were stabilized at the normal approach speed and descent rate. During round-out I slowly reduced the left engine throttle to idle for landing. During flare; a sound -- similar to an antenna scraping the ground -- was noted. I decided to go around not knowing if we were hitting something or dragging something on the runway. During the go around; the flaps were retracted and upon retracting the gear; the handle was found in the 'up' position. No abnormal flight characteristics; engine performance or vibrations were noted. It was decided that we would re-enter the pattern; land and inspect the airplane for any damage. Upon engine shutdown; it was noted that the tips of the propellers and a communications antenna showed signs of ground contact. During the approach and round-out there was no gear warning horn noted by either pilot. I believe the contributing factors were that the throttles were set above the threshold where the gear warning horn would activate and possible fault in the flap position switch (gear warning horn should activate with flaps set at 25 degrees or 40 degrees with landing gear in the up position). Another factor included not following my usual before landing flow; due to my desire to leave the flaps in the up position.

Title: MEI PLT NEARLY LANDS WITH THE GEAR UP ON A TRAINING FLT.

Narrative: DURING MEI TRAINING AT ZZZ; I WANTED TO HAVE THE MEI STUDENT EVALUATE AND CRITIQUE MY PRECAUTIONARY ENG SHUTDOWN AND SIMULATED SINGLE ENG TFC PATTERN/APCH/LNDG. THE R ENG THROTTLE WAS SET TO SIMULATED FEATHER AND THE L ENG THROTTLE WAS SET TO MAINTAIN A NORMAL TFC PATTERN APCH TO LAND. WHILE I WAS PLAYING 'STUDENT' I INTENTIONALLY DID NOT PUT THE FLAPS IN FOR LNDG TO SEE IF THE STUDENT WOULD CORRECT MY ERROR. ON FINAL FOR RWY 9; THE STUDENT MADE ME AWARE THAT THE FLAPS WERE NOT EXTENDED; SO I LOWERED THEM TO THE PRESCRIBED 25 DEGS. WE WERE STABILIZED AT THE NORMAL APCH SPD AND DSCNT RATE. DURING ROUND-OUT I SLOWLY REDUCED THE L ENG THROTTLE TO IDLE FOR LNDG. DURING FLARE; A SOUND -- SIMILAR TO AN ANTENNA SCRAPING THE GND -- WAS NOTED. I DECIDED TO GO AROUND NOT KNOWING IF WE WERE HITTING SOMETHING OR DRAGGING SOMETHING ON THE RWY. DURING THE GAR; THE FLAPS WERE RETRACTED AND UPON RETRACTING THE GEAR; THE HANDLE WAS FOUND IN THE 'UP' POS. NO ABNORMAL FLT CHARACTERISTICS; ENG PERFORMANCE OR VIBRATIONS WERE NOTED. IT WAS DECIDED THAT WE WOULD RE-ENTER THE PATTERN; LAND AND INSPECT THE AIRPLANE FOR ANY DAMAGE. UPON ENG SHUTDOWN; IT WAS NOTED THAT THE TIPS OF THE PROPS AND A COMS ANTENNA SHOWED SIGNS OF GND CONTACT. DURING THE APCH AND ROUND-OUT THERE WAS NO GEAR WARNING HORN NOTED BY EITHER PLT. I BELIEVE THE CONTRIBUTING FACTORS WERE THAT THE THROTTLES WERE SET ABOVE THE THRESHOLD WHERE THE GEAR WARNING HORN WOULD ACTIVATE AND POSSIBLE FAULT IN THE FLAP POS SWITCH (GEAR WARNING HORN SHOULD ACTIVATE WITH FLAPS SET AT 25 DEGS OR 40 DEGS WITH LNDG GEAR IN THE UP POS). ANOTHER FACTOR INCLUDED NOT FOLLOWING MY USUAL BEFORE LNDG FLOW; DUE TO MY DESIRE TO LEAVE THE FLAPS IN THE UP POS.
