Plain English Summary

2/10 complexity

This directive mandates that all Bell 204 series helicopters be retrofitted so the engine fire detection system provides an unmistakable, manually‑silenceable audible warning. Owners/operators must fund and complete the modification by 1 January 1975; compliance is enforced through the Civil Aviation Safety Authority's airworthiness directive regime. The rule sets functional performance (audible, distinct, silencable) but leaves technical solutions and installation details to operators and their maintenance providers.
