Crop-duster crash data reveals maintenance, not pilots, as top risk
OpenAlex · 2026-08-27
Researchers built a computer model mapping how crop-dusting plane crashes happen in Brazil, finding that poor aircraft maintenance and weak oversight cause more accidents than pilot error alone.
1
Analysis of 16 CENIPA accident reports (2017-2024) identified 67 weighted event-factor relationships across 20 causal factors
2
Community detection revealed three risk clusters: Powerplant Failure Syndrome, Organisational Deficiency Cascade, and Low-Altitude Control Loss (modularity Q = 0.207)
3
Betweenness centrality showed maintenance deficiency and supervisory failure act as causal bridges that outrank pilot-error factors, supporting a shift in regulatory focus toward maintenance oversight
