Forensic Report Finds Faulty Screw Mounting Caused Fatal Birstein Turbine Fall

Authorities say no technical defect was found in the turbine, which shifts scrutiny to on-site assembly practices and safety checks.

Overview

  • The work platform inside a wind turbine near Birstein fell during construction on February 25, 2026, killing two 32-year-old workers after a roughly 60-meter drop.
  • A commissioned forensic expert concluded that one of three manually fastened screw connections that held the internal work platform was mounted incorrectly, causing the fixation to fail when crane chains were removed.
  • Investigators from the Staatsanwaltschaft Hanau and Polizeipräsidium Offenbach reported no evidence of material failure or mechanical defects in the turbine components.
  • Authorities say their inquiries are now largely complete, leaving next steps focused on procedural failings, worker training, and possible administrative or legal follow-up.
  • The case highlights a safety vulnerability in how temporary work platforms are secured during turbine assembly and could prompt tighter site checks, clearer mounting protocols, and scrutiny of contractor practices.
