NTSB narrative
According to the first officer, the airplane was being directed to the parking area by a marshaler, who was positioned in front and to the left of the airplane. The first officer looked out his window to observe the right wing's clearance from a blast fence, but could not see the wing tip due to the sun's position behind the airplane. According to a Federal Aviation Administration (FAA) inspector, the captain stated that he knew the wing was close to the fence, but the marshaler was signaling to continue. The airplane's right wing tip then impacted a light pole inside the blast fence, resulting in substantial damage. The captain stated that prior to impact, the marshaler never signaled for the flight crew to stop. The marshaler stated to the FAA inspector that she attempted to signal the captain to stop, but his head was turned to the right. The FAA inspector also reported that the first officer never advised the captain to stop the airplane or use caution.
Probable cause
The flight crew’s failure to maintain adequate wing tip clearance from a light pole during taxi.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
