NTSB narrative
While taxiing as a flight of two, the pilot of the red Beechcraft stopped his airplane so that he could conduct a run-up of the engine. The pilot of the blue Beechcraft lost visual contact with the red Beechcraft while changing frequencies on his radio and impacted the left aft section of the red Beechcraft, which resulted in substantial damage to the left wing.
Both of the pilots reported there were no pre-impact mechanical failures or malfunctions with the airframes or engines that would have precluded normal operation.
Probable cause
While taxiing as a flight of two, the pilot of the blue Beechcraft became distracted and impacted the red Beechcraft which had stopped.

- 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, coordinates. 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.
