Plain English Summary

3/10 complexity

This AD, issued by the Civil Aviation Safety Authority under Part 39, mandates a specific modification to main rotor blades on Bell 204B helicopters, to be carried out exactly as described in Bell Service Letter No. 204B‑68. For blades in service on 14 Feb 1969 the work had to be done within 100 flight hours after that date; blades not in service then must be modified before installation. Owners/operators bear the costs and must change maintenance/procurement practices to ensure mandatory compliance.
