Aircraft Accident/Incident Report

Seattle, Washington 98108
Monday, September 20, 2004 15:35 PDT

NTSB Narrative Summary Released at Completion of Accident

Not familiar with the area where his airplane was parked, the pilot reviewed the airport diagram and taxiways. Still unfamiliar with the taxiway entrances, he elected to maneuver through the parking area and then request access to the taxiway. As he taxied toward the taxiway entrance, and noticing another airplane parked close to his taxi path, he braked to avoid the airplane. As a result of applying too much left brake, the outboard section of the airplane's left wing sustained structural damage after impacting the parked airplane.

NTSB Probable Cause Narrative

The failure of the pilot to maintain clearance with the parked airplane while taxiing. A factor contributing to the accident was the pilot's inadequate preflight planning.
