Mamba Reopens After Missouri Inspectors Red‑Tag Coaster Over Faulty Seat Belts

State inspection documents confirm same‑day replacement of faulty seat belts preceding reopening.

Overview

  • A guest email prompted a Division of Fire Safety spot inspection on Oct. 30 that found more than 20 lap belts or retractors failing to lock properly, leading to a red tag and shutdown.
  • Worlds of Fun implemented Fire Marshal‑requested modifications, the ride was re‑inspected that afternoon, and it was cleared to operate that evening.
  • Six Flags, the park’s parent company, said 18 belt units were replaced out of an abundance of caution.
  • Documents and witness accounts describe an Oct. 11 ride where a couple physically held a distressed girl after her seat belt reportedly came undone, with a separate belt issue reported the next day.
  • The April annual inspection found no issues, and the latest DFS report listed no additional safety concerns beyond the seat belt replacements.
