The Verdica score is a composite trust score from 300 to 850, computed from aircraft airworthiness certificates and enforcement history maintained by the FAA. A score of 850 places ZYLSTRA CYCLE CO INC in IA in the excellent (800–850) band. The score reflects publicly available regulator data — it is not a rating from Verdica itself and does not incorporate paid reviews or advertising.
Verdica combines three weighted sub-scores drawn from the FAA. Each sub-score reflects a different dimension of aviation compliance — certificate status, enforcement actions, and safety incidents — and is normalized against industry peers before being aggregated to the 300–850 scale.
Verdica pulls public records from the FAA: aircraft airworthiness certificates and enforcement history. Data is refreshed on rolling cycles, typically weekly to monthly depending on the source agency's own update schedule. See the "source data current" indicator on the entity page for the last successful refresh.
Common negative signals include revoked certificates, enforcement actions, or airworthiness directives. Any of these appear in the underlying regulator records and pull the sub-score down; the composite reflects the weighted impact.
