The NTSB's narrative final · quoted from the NTSB record

The on-demand cargo flight had been uneventful until the pilot made his landing approach. When he lowered the landing gear, the right main landing gear failed to extend and lock. A low pass was made and tower personnel confirmed that the landing gear was not extended. The pilot followed emergency procedures in an attempt to extend the landing gear, but to no avail. He made an intentional gear up landing. Postaccident examination disclosed that the right forward inboard landing gear door hinge pin (p/n 46652-2) had broken, preventing the landing gear from extending.
