AD/L.40/4 - Elevator and Rudder Control System - Modification - CANCELLED

What this is: This document cancels a previous safety rule (called an Airworthiness Directive or AD) that applied to a specific type of aircraft—the Meta Sokol L.40 series.

What it used to require: The original rule required aircraft owners to replace wires in the elevator and rudder control systems with approved flexible cables. This was a one-time modification that had to be completed before September 1971.

Why it's cancelled: The Civil Aviation Safety Authority (CASA) has determined this safety requirement is no longer necessary. The directive is formally cancelled effective 27 August 2009.

Who is affected: Owners and operators of Meta Sokol L.40 series aeroplanes, though given the 1971 deadline and the 2009 cancellation, this primarily affects historical compliance records.
