The private pilot stated that the purpose of the flight was for him to receive instruction from the rear-seated certified flight instructor (CFI). Following departure, they flew to a nearby airport with the intent of performing touch-and-go practice takeoffs and landings. As the airplane approached the touchdown zone, the private pilot prematurely flared. The CFI assumed control of the airplane and decreased the pitch attitude while simultaneously applying engine power. Despite his attempts, the airplane contacted the runway hard in a nose-high attitude. The CFI opted to abort the landing and climbed to traffic pattern altitude to verify proper control input. He landed on the same runway without incident.In the section titled "RECOMMENDATION" in the NTSB Pilot/Operator Report, form 6120.1/2, the pilots stated that the accident could have been prevented if they had flared closer to the runway. During the impact sequence, the airplane sustained substantial damage to the fuselage structure. Both pilots reported that there were no pre impact mechanical malfunctions or failures that would have precluded normal operation.
