N21231

The pilot reported that while he was on a normal approach with the flaps in the full extended position, he observed powerlines prior to the runway. He reported that he focused on clearing the powerlines and lost track of the airplane's speed. The airplane cleared the powerlines and, shortly after, the airplane descended rapidly. The airplane struck the ground hard and bounced before it impacted the ground a second time in a nose low attitude. The airplane flipped over and came to rest inverted just short of the runway surface. During the accident sequence, the airplane's wings and empennage were substantially damaged. The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
