Plain English Summary

1/10 complexity

What this does: This document officially cancels a previous safety rule (called an Airworthiness Directive) that applied to Eurocopter SA 360 and SA 365 (Dauphin) helicopters.

Who it affects: Owners and operators of these specific helicopter models.

Why it matters: Previously, operators had to follow special inspection rules for the 'main rotor rotating star' (a critical rotating component that connects rotor blades to the hub). New engineering data showed that cracks in this part grow very slowly and will be caught during normal scheduled maintenance anyway. Therefore, the extra safety rule is no longer needed. This saves operators time and money while maintaining safety standards.

Key date: The cancellation took effect on 28 September 2006.

Requirement:	CANCELLED.
	This AD is cancelled on 28 September 2006.
Background:	The results of examinations and analyses have shown that the rate of crack growth is very slow and that the TBO for these assemblies is sufficient for a crack to be detected before it becomes critical. Consequently, this Directive is cancelled. EASA AD 2005-6353R1 refers.
