Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Taxi
Defining eventThe 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
Ground collision
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 pilot reported that while taxiing from a grass tiedown area, the airplane’s left wingtip struck the propeller of a parked airplane. She did not notice the wingtip strike, so she continued to taxi and obtained her instrument flight rules (IFR) clearance. After transitioning to the paved taxiway yellow centerline stripe, the airplane’s right wing tip struck the propeller of a second parked airplane. The pilot shut down the engine and exited the airplane to examine the damage. The airplane sustained minor damage to both wings. The incident occurred during the annual Experimental Aircraft Association AirVenture fly-in. The airport issued a Notice to Air Mission that was active at the time of the incident that advised operators “FBO RAMP, T HANGER RAMP PRKG NOT STD.” The pilot stated that it was not clear to her what this meant. The pilot recommended that additional personnel for wing walkers could have prevented the incident. According to the Aeronautical Information Manual, being centered on the taxiway centerline does not guarantee wingtip clearance with other aircraft or other objects.

Probable cause

The pilot’s failure to maintain adequate wingtip clearance while taxiing. Contributing to the accident was the ambiguous nonstandard parking at the time of the incident.

  • 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, cause areas. 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.
