The aircraft sustained substantial damage and the private pilot was not injured. Dark night visual meteorological conditions prevailed for this cross-country flight operating under Title 14 CFR Part 91 and no flight plan was filed.

He was on roll out and had raised the flaps for takeoff when he heard a noise and felt a "hard bump." He said he notified the tower that "something was wrong and there may be broken parts on the runway." He said he noted that right brake did not work, then taxied to the ramp and inspected the aircraft.
