NTSB narrative
The commercial pilot/owner was conducting an agricultural application flight in the helicopter. A witness reported observing the helicopter flying about 200 ft above ground level and then descending to just above the sugarcane tops. The helicopter then pitched down and impacted terrain, and it was destroyed.
About 3 days before the accident, the helicopter received a Federal Aviation Administration (FAA) ramp check, during which numerous discrepancies with the helicopter were found including, in part, a cracked tailboom tube structure, rusted bolts with improper grip lengths, a disabled transmission chip light, a worn transmission gear with a backed-off locknut, and a lack of proper lubrication. The FAA inspector noted that the helicopter was in a poor condition and considered to be unairworthy. The pilot/owner, who was also a licensed mechanic, performed his own maintenance. It is unlikely that the pilot corrected the maintenance issues in the intervening 3 days; therefore, the airplane was likely unairworthy at the time of the accident. The accident is consistent with the loss of helicopter control for reasons that could not be determined because the helicopter was destroyed at impact.
Probable cause
The pilot’s improper decision to operate an unairworthy helicopter, which resulted in a loss of control and subsequent impact with terrain.

- 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.
