Departure was normal; with a quick 13 min flight to ZZZZ. After a descent to pattern altitude; landing configuration was established. Final checks were done on about a two mile final. Gear indicators were established on final and all that remained to be done was a smooth touchdown considering the winds were nice and smooth from the east. After touchdown; we rolled about 20 feet and I noticed the right wing start to drop slowly towards the ground. The aircraft then proceeded to veer to the right after the airframe made contact with the surface. The aircraft was shut down by the time it came to a stop. At this time it has not yet been established as to why the gear failed.
BE99 Captain experienced the collapse of the right main landing gear upon landing; cause unknown.
