The old rule (AD/PFP/11) required specific reconditioning procedures for **Sensenich fixed-pitch propellers** (propellers with blades set at a fixed angle, commonly found on small aircraft).\n\n**Why it was cancelled:** The safety requirements are now covered elsewhere — specifically in the manufacturer's own repair manual and in another aviation order (CAO 107 AD/PROP/1). Rather than duplicate these rules, CASA has withdrawn this directive.\n\n**Who it affects:** \n- Owners and operators of aircraft with Sensenich fixed-pitch propellers\n- Aircraft maintenance engineers and repair stations\n\n**Why it matters:** If you were following this specific directive, you no longer need to — but you must still follow the manufacturer's repair manual and the other aviation order mentioned.
