Aircraft Accident/Incident Report
Knoxville, Tennessee 37701
Monday, December 3, 2012 15:50 EST
NTSB Narrative Summary Released at Completion of Accident
At the conclusion of an evaluation flight, the left seat pilot taxied the airplane to the hangar area under the direction of the right seat pilot. After reaching the hangar area, the left seat pilot initiated a 180-degree turn in order to better position the airplane for postflight ground handling. During the turn, the right side of the horizontal stabilizer struck one of the hangar’s support beams, resulting in substantial damage to the horizontal and vertical stabilizers, as well as the empennage. Following the accident, the operator instituted a new policy, which stated that an external spotter should be used when maneuvering in the vicinity of obstacles.
NTSB Probable Cause Narrative
The pilots’ decision to maneuver the airplane in close proximity to a hangar.
