Aviation Accident Summary ERA10CA425

Fort Myers, FL, USA

Aircraft #1

N5382K

RYAN NAVION B

Analysis

According to the pilot, during a previous flight he discovered that the elevator trim adjustment wheel was binding when it set to the full airplane nose-up position. He planned to have the airplane inspected by a mechanic at the conclusion of that flight, but upon arriving at the destination, all of the facilities were closed for the evening. He subsequently departed for the return flight after picking up passengers, and as he began to trim the airplane for the landing flare, the airplane pitched up uncontrollably. As the pilot attempted to recover the airplane, the left wing struck the ground, resulting in substantial damage. An examination of the wreckage by a Federal Aviation Administration inspector revealed that the trim wheel was binding on the instrument panel when the trim was set to a nose-up position. When the trim wheel was removed from the trim system, the remainder of the mechanism was free to move in both the up and down directions.
