Aviation Accident Summary GAA17CA474

Bettles, AK, USA

Aircraft #1

N9664X

CESSNA 210

Analysis

The pilot reported that he overflew a remote airstrip, which was bounded by a lake on the approach end. He added that he circled back to land and that, during final approach, he encountered "glassy water and bright sun." Subsequently, the airplane landed short of the runway in the lake, sunk in more than 500 ft of water, and was not recovered. The Federal Aviation Administration aviation safety inspector who interviewed the pilot reported that he stated that the sun and the reflection off the lake gave him the impression that the airplane was higher than it was. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
