AD/AS 355/26 Amdt 1 - Tail Rotor Control Spider - CANCELLED

What this does: This document cancels a previous aviation safety rule that required helicopter operators to inspect the tail rotor control spider on specific Eurocopter AS 355 helicopters.

Who it affects: Owners and operators of Eurocopter AS 355 (Twin Ecureuil) series helicopters.

Key details:

• Cancels the previous Airworthiness Directive (AD/AS 355/26) effective 30 July 2009
• Removes the requirement to inspect the tail rotor control spider assembly every 100 flight hours or whenever it was installed
• Stops the mandatory compliance with manufacturer telexes 11185 and 11538 from 1987

Why it matters: The safety inspections are no longer necessary, likely because manufacturer service bulletins have superseded the requirement or the affected components are no longer in widespread service. This reduces maintenance costs and administrative burden for helicopter operators while maintaining safety standards.
