- 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
- Collision during takeoff/landing
- 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 of the amphibious airplane reported that, while taking off from a lake, unforeseen wakes that resulted in a decay the airplane’s airspeed. The pilot said that he was already committed to takeoff and initiated a climb at the airplane’s best rate of climb. While maneuvering to avoid obstructions, the left wing impacted a vehicle, and the airplane came to rest between two water tanks. The airplane sustained substantial damage to the fuselage and both wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The inadvertent encounter with water wake during the takeoff sequence that degraded the airplane’s airspeed and resulted in the pilot’s failure to maintain clearance from obstacles during the initial climb.

- 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.
