Narrative:

After dropping a load of skydivers from 13500 ft MSL I usually lower the gear for the extra drag for the descent. During the descent I went further north of the field than usual. At about 5000 MSL I retracted the gear so I would not have to add any power to make it back to the field. There was no traffic in the area so I reported on left base for the runway. I went through my usual checklist including gear down. Again on final I went through list including gear down. Coming in on final a bunch of the skydivers came running out towards the runway. I started looking for other traffic or trying to figure what they wanted me to go around for. I saw no other traffic or heard none on the radio so I proceeded the approach. No one was standing on the runway so I figured they were messing around. About the time I thought the gear was going to touch I heard the noise of the propellers touching. I gave it full power and lifted the nose. I could tell by the feel that I was not going to be able to climb. The propellers weren't hitting but I was not getting any climb rate going. With only 3000 ft of runway I pulled the throttles to idle and landed flat as possible. When the aircraft came to a stop I looked at the gear selector and it was in the down position, but the red light was on. I don't know in my own mind if it was red the whole time or just after I came to a stop. I am going to do a retract test on jacks for the FAA. Then I should have a better idea of why the gear did not come down.

Title: GEAR UP LNDG IN SMT TWIN AFTER PARACHUTE JUMPING ACTIVITY IS TERMINATED.

Narrative: AFTER DROPPING A LOAD OF SKYDIVERS FROM 13500 FT MSL I USUALLY LOWER THE GEAR FOR THE EXTRA DRAG FOR THE DSCNT. DURING THE DSCNT I WENT FURTHER N OF THE FIELD THAN USUAL. AT ABOUT 5000 MSL I RETRACTED THE GEAR SO I WOULD NOT HAVE TO ADD ANY PWR TO MAKE IT BACK TO THE FIELD. THERE WAS NO TFC IN THE AREA SO I RPTED ON L BASE FOR THE RWY. I WENT THROUGH MY USUAL CHKLIST INCLUDING GEAR DOWN. AGAIN ON FINAL I WENT THROUGH LIST INCLUDING GEAR DOWN. COMING IN ON FINAL A BUNCH OF THE SKYDIVERS CAME RUNNING OUT TOWARDS THE RWY. I STARTED LOOKING FOR OTHER TFC OR TRYING TO FIGURE WHAT THEY WANTED ME TO GAR FOR. I SAW NO OTHER TFC OR HEARD NONE ON THE RADIO SO I PROCEEDED THE APCH. NO ONE WAS STANDING ON THE RWY SO I FIGURED THEY WERE MESSING AROUND. ABOUT THE TIME I THOUGHT THE GEAR WAS GOING TO TOUCH I HEARD THE NOISE OF THE PROPS TOUCHING. I GAVE IT FULL PWR AND LIFTED THE NOSE. I COULD TELL BY THE FEEL THAT I WAS NOT GOING TO BE ABLE TO CLB. THE PROPS WEREN'T HITTING BUT I WAS NOT GETTING ANY CLB RATE GOING. WITH ONLY 3000 FT OF RWY I PULLED THE THROTTLES TO IDLE AND LANDED FLAT AS POSSIBLE. WHEN THE ACFT CAME TO A STOP I LOOKED AT THE GEAR SELECTOR AND IT WAS IN THE DOWN POS, BUT THE RED LIGHT WAS ON. I DON'T KNOW IN MY OWN MIND IF IT WAS RED THE WHOLE TIME OR JUST AFTER I CAME TO A STOP. I AM GOING TO DO A RETRACT TEST ON JACKS FOR THE FAA. THEN I SHOULD HAVE A BETTER IDEA OF WHY THE GEAR DID NOT COME DOWN.
