NTSB narrative
The airline transport pilot was departing on an on-demand air taxi flight from a remote saltwater bay in a float-equipped airplane. He reported that just as the floats came on step, the floats contacted a large wave, which bounced the airplane about 15 feet into the air. As the airplane descended, a second wave struck the floats. The operator's maintenance personnel later discovered structural damage to longerons adjacent to the airplane's firewall, which required replacement. The pilot reported that there were no preaccident mechanical problems with the airplane.
Probable cause
The pilot's selection of an unsuitable takeoff area, which resulted in an in-flight collision with ocean waves. A factor associated with the accident was large waves/swells.

- 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: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2003-08-14.
