N76097

The pilot reported that he kept the airspeed to a minimum while on short final because he intended to conduct a short field landing. He reported that as the tailwheel equipped airplane cleared the trees on the approach end of the runway, a "significant sink rate" developed. The pilot applied power, but it was insufficient to arrest the descent rate. The airplane landed hard on the main wheels and the propeller impacted the grass runway. The airplane nosed over during the landing roll which resulted in substantial damage to the firewall and empennage. The pilot reported that there was no malfunction or system failure of the airplane before the accident.
