During landing, the airplane exited the right side of the runway and the left wing impacted the ground. The pilot taxied to his hangar. Postaccident examination was delayed several months (until December 11, 2000) to allow Sukhoi representatives to assess the damage. They determined that several structural tubes just aft of the engine firewall needed to be replaced. The damaged area of the fuselage was where the main landing gear attached to the fuselage. It could not be determined if the structural damage that occurred on August 14, 2000, was the result of one landing or progressive damage from several landings. The tubes that needed replacement following the August 14, 2000, event had been previously damaged (bent or broken) during an accident on May 11, 1996. At that time, several unsuccessful attempts were made to acquire Russian materials and technical assistance. The decision was made to perform the repairs using American materials. According to the Sukhoi representatives, the American tubing and welding rods were 'incompatible' with the original Russian materials.
Probable Cause: The inadequate structural materials (American manufactured verses original Russian materials) used during a major repair.
