About 25 Days (9.3 Hours) Before The Accident, The Airframe Was Modified With Different Landing Gear Legs, Wheels, And Brakes Analysis: The pilot reported that during the landing roll on the dry grass strip, he was making corrections with the brakes and the airplane nosed over, coming to rest inverted. The pilot assumed that he was “a bit too aggressive” with the brakes. The airplane sustained substantial damage to the right wing strut and the rudder. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. The pilot further reported that the accident could have been prevented by “less or no excessive braking” during the landing roll.
