AD/PA-24/29 - Rudder Balance Weight - Installation - CANCELLED

This document officially cancels an old aviation safety rule for Piper PA-24 Comanche aircraft.

The Civil Aviation Safety Authority (CASA) has scrapped Airworthiness Directive AD/PA-24/29, which originally forced owners of these specific light aircraft to install a balance weight on the rudder. This physical modification was intended to prevent dangerous flutter (rapid vibration) in the tail section.

Key points:

• What changed: The requirement to install this rudder weight—originally mandated back in the 1970s—is now completely removed from the regulations.
• Who is affected: Owners and operators of Piper PA-24 (Comanche) series aeroplanes.
• What this means: While the original deadline to install the weight was February 1973, this cancellation officially erases the legal obligation entirely as of 23 October 2008. This cleans up the rulebook and confirms that compliance with this specific, decades-old directive is no longer legally required, even if an aircraft missed the original deadline.
