[After takeoff] I selected gear up. Shortly after I heard and felt a large thud as of the gear was having trouble retracting. I looked at gear lights in cockpit to discover the gear handle illuminated indicating gear unsafe and my left main gear light still green indicating that it was down and locked. After climbing to safe altitude of 5000 MSL I pulled out emergency gear extension checklist and followed the procedures. Procedures call for the landing gear relay circuit breaker to be pulled so gear motor would stop running. I then started to pump the emergency gear extension handle rapidly in an attempt to manually lower gear. As I was doing this I navigated the plane to my next intended destination in the hopes I could manually extend it and then land. I radioed [the] FBO to see if they could come out to runway and take a look at my gear as I flew 500 ft above the runway. They indicated my nose gear was 'in trail' and my mains appeared to be down. In addition to [the] FBO I was also in contact with my company trying to decide what the best course of action for me.It was decided it was best for me to fly back to [departure airport] due to the availability of emergency crews and also that is where our company is based out of. I had plenty of fuel to get there. During the roughly 1.5 hour flight back I would occasionally keep pumping emergency extension handle in the hopes I would get a green light on nose wheel. The gear extension handle did not seem to get any more resistant indicating that it was working. No light for the nose wheel illuminated either. I did a tower requested flyby and then lined back up for runway and successfully completed a no nose wheel landing. Upon touchdown my right main gear collapsed. The lights in the cockpit indicated the right main was down and locked. Most likely I was getting a false indication. After my right gear collapsed I slid on the runway for about 1000 feet before coming to a complete stop. After which I closed the fuel valve handles and turned off master/ battery and exited the plane to the rear. Very minimal damage to the plane occurred. I; the sole occupant; was uninjured.
Beech 99 pilot reported noting abnormal landing gear indications upon gear retraction after takeoff. The right main gear collapsed on landing resulting in minimal damage.
