Narrative:

I was giving flight instruction for my multi-engine student. We were simulating engine-out lndgs. I pulled the throttle back on crosswind. On downwind, my student put down the gear as part of his prelndg checklist. Somewhere between base and final he brought the gear back up. I failed to recognize this and we proceeded to land. Neither of us heard the gear up warning horn, so there was no warning until there was a radio call right before we touched down on the runway. We touched down and slid to a stop on the runway. I cut off the fuel, and instructed my student to shut the master switch off. There was minimal damage to the aircraft and no personal injuries. I think that the incident was caused by a large number of things happening at the same time. An engine-out situation, a poor approach, and trouble on final caused both of us to be very busy during the final approach, and miss the gear-up situation. Since neither of us heard the gear-up warning horn, a possible untimely failure of a gear warning system may have contributed to create the incident. Supplemental information from acn 552534: on downwind, I put down the gear as part of my prelndg checklist. I then had to bring it back up because I was losing altitude too rapidly. When I turned to final, I was too high and too fast. As I was trying to correct for that, I forgot to re-extend the landing gear. The instructor was also trying to assist me with the landing. On final, we both forgot to check the gear indicator lights.

Title: GEAR UP LNDG IN A PA34 SENECA DURING A SIMULATED 1 ENG OP APCH TRAINING FLT AT A NON TWR ARPT, N14, NJ.

Narrative: I WAS GIVING FLT INSTRUCTION FOR MY MULTI-ENG STUDENT. WE WERE SIMULATING ENG-OUT LNDGS. I PULLED THE THROTTLE BACK ON XWIND. ON DOWNWIND, MY STUDENT PUT DOWN THE GEAR AS PART OF HIS PRELNDG CHKLIST. SOMEWHERE BTWN BASE AND FINAL HE BROUGHT THE GEAR BACK UP. I FAILED TO RECOGNIZE THIS AND WE PROCEEDED TO LAND. NEITHER OF US HEARD THE GEAR UP WARNING HORN, SO THERE WAS NO WARNING UNTIL THERE WAS A RADIO CALL RIGHT BEFORE WE TOUCHED DOWN ON THE RWY. WE TOUCHED DOWN AND SLID TO A STOP ON THE RWY. I CUT OFF THE FUEL, AND INSTRUCTED MY STUDENT TO SHUT THE MASTER SWITCH OFF. THERE WAS MINIMAL DAMAGE TO THE ACFT AND NO PERSONAL INJURIES. I THINK THAT THE INCIDENT WAS CAUSED BY A LARGE NUMBER OF THINGS HAPPENING AT THE SAME TIME. AN ENG-OUT SIT, A POOR APCH, AND TROUBLE ON FINAL CAUSED BOTH OF US TO BE VERY BUSY DURING THE FINAL APCH, AND MISS THE GEAR-UP SIT. SINCE NEITHER OF US HEARD THE GEAR-UP WARNING HORN, A POSSIBLE UNTIMELY FAILURE OF A GEAR WARNING SYS MAY HAVE CONTRIBUTED TO CREATE THE INCIDENT. SUPPLEMENTAL INFO FROM ACN 552534: ON DOWNWIND, I PUT DOWN THE GEAR AS PART OF MY PRELNDG CHKLIST. I THEN HAD TO BRING IT BACK UP BECAUSE I WAS LOSING ALT TOO RAPIDLY. WHEN I TURNED TO FINAL, I WAS TOO HIGH AND TOO FAST. AS I WAS TRYING TO CORRECT FOR THAT, I FORGOT TO RE-EXTEND THE LNDG GEAR. THE INSTRUCTOR WAS ALSO TRYING TO ASSIST ME WITH THE LNDG. ON FINAL, WE BOTH FORGOT TO CHK THE GEAR INDICATOR LIGHTS.
