Narrative:

After having made 3 full-stop night lndgs for recurrency, the pilot was performing a simulated engine-out landing by bringing the throttle back to idle abeam the T/D zone. Upon reaching the runway and touching down, he realized that the gear had not been extended. I believe that the problem occurred for the following reasons: 1) pilot may have not pulled all the way off, resulting in no gear warning horn being sounded. 2) diversion from usual gumps check due to the unusual nature of the simulated power-off landing (pilot and instrument were keeping their attention outside of the aircraft, judging altitude and distance for landing on the #'south). To prevent this type of occurrence, it is imperative that both pilot and instrument complete prelndg checklists before every landing.

Title: PLT OF SMA MAKING NIGHT LNDGS FOR NIGHT REQUALIFICATION. LANDED GEAR UP.

Narrative: AFTER HAVING MADE 3 FULL-STOP NIGHT LNDGS FOR RECURRENCY, THE PLT WAS PERFORMING A SIMULATED ENG-OUT LNDG BY BRINGING THE THROTTLE BACK TO IDLE ABEAM THE T/D ZONE. UPON REACHING THE RWY AND TOUCHING DOWN, HE REALIZED THAT THE GEAR HAD NOT BEEN EXTENDED. I BELIEVE THAT THE PROB OCCURRED FOR THE FOLLOWING REASONS: 1) PLT MAY HAVE NOT PULLED ALL THE WAY OFF, RESULTING IN NO GEAR WARNING HORN BEING SOUNDED. 2) DIVERSION FROM USUAL GUMPS CHK DUE TO THE UNUSUAL NATURE OF THE SIMULATED PWR-OFF LNDG (PLT AND INSTR WERE KEEPING THEIR ATTN OUTSIDE OF THE ACFT, JUDGING ALT AND DISTANCE FOR LNDG ON THE #'S). TO PREVENT THIS TYPE OF OCCURRENCE, IT IS IMPERATIVE THAT BOTH PLT AND INSTR COMPLETE PRELNDG CHKLISTS BEFORE EVERY LNDG.
