NTSB narrative

The ground collision occurred as one airplane (Cessna 172) was situated in the runup area, and another airplane (Gulfstream G280) was taxiing to a fixed based operator (FBO). The Gulfstream had landed and passed the turn for the FBO and was instructed by the ground controller to turn 180° and taxi to the FBO. The pilots of both airplanes were aware of each other and confirmed they had each other in sight. As the Gulfstream taxied past the Cessna, the right wing of the Gulfstream struck the left wing of the Cessna, which resulted in substantial damage to the left wing and aileron. The Gulfstream sustained minor damage to the right winglet leading edge. Both pilots reported that there were no preaccident mechanical malfunctions or failures with the airplanes that would have precluded normal operation.

Probable cause

The Gulfstream pilot’s failure to maintain clearance from the Cessna while taxiing that resulted in a ground collision.

  • 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, cause areas. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2024-09-21.
