First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary

DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

The airplane ground looped during the takeoff roll. The pilot reported that the airplane started to veer to the left as he increased engine power for the takeoff roll on runway 11 (6,525 feet by 150 feet, concrete). The pilot reduced engine power to idle as the airplane departed off the left side of the runway. The right wingtip, tip rib, and aileron were damaged during the ground loop. The pilot reported that his rapid advance of engine power and inadequate use of up-elevator (backstick) contributed to the tail becoming prematurely airborne and the subsequent loss of directional control. The winds were reported to be variable at 5 knots.

Probable cause

The pilot's failure to maintain directional control during takeoff roll which resulted in a ground loop.

  • 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.
  • API snapshot SHA-256: ad635b4ea1fc6e949f12a69036c25eb990f7a579fdd43d6c70ae807c058b5aab; retrieved 2026-09-22T03:24:17.503Z.
