NTSB narrative
The pilot reported that after he requested and received permission from the tower air traffic controller to taxi from the main terminal to the runway, he proceeded to taxiway A to prepare for takeoff. He passed the taxiway and the tower controller cleared him to turn back to the taxiway. The pilot initiated a right 270-degree turn and as the airplane nose crossed the taxiway centerline, he made a shallow left turn into the run up area. The pilot stated that during this turn he lost sight of the moving fuel truck and shortly thereafter, the left wing tip impacted the front of the fuel truck.
Probable cause
The failure of the pilot to maintain adequate clearance/distance from the fuel truck 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2010-04-09.
