Narrative:

I had descended to pattern altitude and was slowing to the 120 mph gear speed. I put the gear handle down. At that time another aircraft was departing in the opposite direction so I extended my downwind. This was a distraction and caused me to change my normal procedures. I lowered the flaps and went through the gumps check on the base leg and on final. On final I had a parachute coming down close to the runway and I had to divide my attention on landing. I have a habit of pointing to the gauge or the lever going through the check. I touched down gear up and slid down and off the left side of the runway into the grass. There was no fire and no injuries. After I came to a stop I shut off the fuel selectors, the magnetos, and the batteries. After I ascertained that everything was stable I checked and the gear handle was down, the gear indicator said up. The gear horn did not sound at any time. I must have locked at the indicator and did not see what I thought I saw. On lifting the aircraft we had to crank and pry the gear into the down position. The factors that I feel contributed to the incident were: 1) being distracted several times during the approach to landing. 2) the gear horn not functioning. 3) after going through the checklist so many times previously, I just went through the motions.

Title: PLT OF AN SMT TWIN ENG SKY DIVING ACFT LANDED GEAR UP RESULTING IN NO INJURIES AND ONLY MINOR DAMAGE TO THE ACFT.

Narrative: I HAD DSNDED TO PATTERN ALT AND WAS SLOWING TO THE 120 MPH GEAR SPD. I PUT THE GEAR HANDLE DOWN. AT THAT TIME ANOTHER ACFT WAS DEPARTING IN THE OPPOSITE DIRECTION SO I EXTENDED MY DOWNWIND. THIS WAS A DISTR AND CAUSED ME TO CHANGE MY NORMAL PROCS. I LOWERED THE FLAPS AND WENT THROUGH THE GUMPS CHK ON THE BASE LEG AND ON FINAL. ON FINAL I HAD A PARACHUTE COMING DOWN CLOSE TO THE RWY AND I HAD TO DIVIDE MY ATTN ON LNDG. I HAVE A HABIT OF POINTING TO THE GAUGE OR THE LEVER GOING THROUGH THE CHK. I TOUCHED DOWN GEAR UP AND SLID DOWN AND OFF THE L SIDE OF THE RWY INTO THE GRASS. THERE WAS NO FIRE AND NO INJURIES. AFTER I CAME TO A STOP I SHUT OFF THE FUEL SELECTORS, THE MAGNETOS, AND THE BATTERIES. AFTER I ASCERTAINED THAT EVERYTHING WAS STABLE I CHKED AND THE GEAR HANDLE WAS DOWN, THE GEAR INDICATOR SAID UP. THE GEAR HORN DID NOT SOUND AT ANY TIME. I MUST HAVE LOCKED AT THE INDICATOR AND DID NOT SEE WHAT I THOUGHT I SAW. ON LIFTING THE ACFT WE HAD TO CRANK AND PRY THE GEAR INTO THE DOWN POS. THE FACTORS THAT I FEEL CONTRIBUTED TO THE INCIDENT WERE: 1) BEING DISTRACTED SEVERAL TIMES DURING THE APCH TO LNDG. 2) THE GEAR HORN NOT FUNCTIONING. 3) AFTER GOING THROUGH THE CHKLIST SO MANY TIMES PREVIOUSLY, I JUST WENT THROUGH THE MOTIONS.
