Narrative:

After takeoff at approximately 300 ft AGL just after gear retraction the copilot's side door came open. There was quite a bit of runway remaining so a landing was attempted. Power was first reduced and then added to start a descent and to prevent a stall. The nose was pitched over at the same time. As the aircraft was rounded out into a landing attitude it was discovered that the gear was up. During the go around that was then made a noise was heard. After circling to land and close the door it was determined that there was no apparent problem. No vibrations or indication gave evidence of a problem. The flight was then continued to destination and upon shutdown the left propeller was found to have struck the ground. This flight was the 3RD of the day and we were late getting off. I was angry at the controllers and rushing. I believe the main cause was my desire to land on the remaining runway due to its length and that the condition (door opening) occurred right at gear retract. I do not remember putting gear up and so I think I did not consider the gear again.

Title: PLT OF A BE58 HAS THE R SIDE DOOR OPEN AFTER LIFT-OFF AT DAL. PLT FORGETS THAT HE HAD RETRACTED THE GEAR AND ATTEMPTS A GEAR UP LNDG. UPON HEARING A 'NOISE' HE MAKES A GAR AND THEN, DISREGARDING THAT 'NOISE' HE CONTINUES ON TO DEST ARPT. POSTFLT INSPECTION FOUND DAMAGE TO THE L PROP.

Narrative: AFTER TKOF AT APPROX 300 FT AGL JUST AFTER GEAR RETRACTION THE COPLT'S SIDE DOOR CAME OPEN. THERE WAS QUITE A BIT OF RWY REMAINING SO A LNDG WAS ATTEMPTED. PWR WAS FIRST REDUCED AND THEN ADDED TO START A DSCNT AND TO PREVENT A STALL. THE NOSE WAS PITCHED OVER AT THE SAME TIME. AS THE ACFT WAS ROUNDED OUT INTO A LNDG ATTITUDE IT WAS DISCOVERED THAT THE GEAR WAS UP. DURING THE GAR THAT WAS THEN MADE A NOISE WAS HEARD. AFTER CIRCLING TO LAND AND CLOSE THE DOOR IT WAS DETERMINED THAT THERE WAS NO APPARENT PROB. NO VIBRATIONS OR INDICATION GAVE EVIDENCE OF A PROB. THE FLT WAS THEN CONTINUED TO DEST AND UPON SHUTDOWN THE L PROP WAS FOUND TO HAVE STRUCK THE GND. THIS FLT WAS THE 3RD OF THE DAY AND WE WERE LATE GETTING OFF. I WAS ANGRY AT THE CTLRS AND RUSHING. I BELIEVE THE MAIN CAUSE WAS MY DESIRE TO LAND ON THE REMAINING RWY DUE TO ITS LENGTH AND THAT THE CONDITION (DOOR OPENING) OCCURRED RIGHT AT GEAR RETRACT. I DO NOT REMEMBER PUTTING GEAR UP AND SO I THINK I DID NOT CONSIDER THE GEAR AGAIN.
