A post-accident examination revealed that the nose landing gear retention bolt had sheared and the airplane had sustained substantial damage to the right wing. The pilot stated that he was the second owner and noticed that the original builder had not followed the design plans for the airplane, so the pilot modified the nose wheel attach plate to strengthen it but did not modify the gear assembly attach point which resulted in the failure.
