Plain English Summary

2/10 complexity

What this is: A mandatory safety instruction (called an Airworthiness Directive) issued by the aviation regulator requiring a specific mechanical fix on vintage aircraft propellers.

Who it affects: Owners and operators of C.A.C. CA-28 (Ceres) series aeroplanes—agricultural aircraft built in Australia during the 1950s and 1960s—but only if fitted with a specific type of propeller (high solidity propeller part number 284402).

What you must do: Before installing one of these propellers on the aircraft, you must modify the propeller counterweights (balancing weights) according to the manufacturer's Service Bulletin No. 33.

Alternative compliance: If you've already carried out modifications under a previous directive (AD/CA-28/2), that satisfies this requirement—you don't need to do it again.

Why it matters: Propeller counterweights are critical for safe operation. This rule prevents unsafe propeller installations that could lead to mechanical failure in flight.
