What happened
The private pilot reported that the flight proceeded without incident until the aircraft landed on Runway 26L. Following the landing, the pilot initiated an exit maneuver by turning right onto Taxiway Echo. During this turn, the left wing of the airplane contacted both the runway surface and an elevated taxiway light stanchion. The impact resulted in substantial damage to the left wing structure.
The investigation
NTSB investigators interviewed the pilot regarding potential mechanical issues that might have contributed to the accident. The pilot stated there were no preaccident mechanical anomalies. He attributed the loss of control during the exit turn to excessive speed for the radius of the turn, noting he was "going a bit fast".
Findings
The primary factor in this incident was the pilot's decision to execute a runway exit turn at a speed exceeding the safe limit for the maneuver. This resulted in the wingtip striking fixed ground infrastructure, specifically the taxiway light stanchion.
