Aviation Accident Summary GAA20CA043

Knoxville, TN, USA

Aircraft #1

N801PZ

Zenair ZENITH 801

Analysis

The pilot reported that, during a power-off 180° approach, he noticed the airplane was "drifting" and would not reach the intended touchdown point. He added power to correct and then reduced the power to idle to resume the approach. On short final, the airplane encountered a "wind shift or gust" and developed a high sink rate. He applied power and lowered the nose, but the airplane landed hard. The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
