At about 1745 Eastern time, the airplane was substantially damaged during the landing rollout. The two pilots and crew chief aboard were not injured. Visual conditions prevailed.
During the landing rollout, both pilots felt the right wing drop and heard a noise like “a blown tire.” They attempted to maintain directional control of the airplane, but the right wing dropped further and the airplane veered off the right side of the runway. The airplane came to rest in the grass beside the runway; the pilots secured the airplane, and then exited without incident. Subsequent examination revealed sustained substantial damage to the right engine firewall and a broken right main landing gear shock strut drag arm.
