- Initial climb
- 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
- Aircraft wake turbulence encounter
- 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 stated that, before departing in his tailwheel-equipped airplane, a U.S. Army CH-47 heavy-lift helicopter departed and proceeded upwind. When the helicopter was established on the downwind leg of the traffic pattern, the pilot initiated his takeoff. At 40 ft above ground level in the initial climb, the airplane “hit the helicopter’s rotor wash” which rolled the airplane “about 135 degrees to its right.” The pilot was able to level the wings before the airplane touched down in low brush to the right of the runway and came to rest near the airport boundary fence. The airplane sustained substantial damage to the main landing gear support structure and the pilot deplaned uninjured. The pilot reported there were no mechanical malfunctions or anomalies with the airplane that would have precluded normal operation.
Probable cause
The pilot’s inadvertent encounter with helicopter wake turbulence during initial climb, which resulted in a loss of airplane control.

- 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, 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.
