AD/BEECH 23/12 - Attachment of ADF Noise Suppressor Capacitor - CANCELLED

What this is: This document officially cancels an old aircraft safety rule (called an Airworthiness Directive or AD) that applied to specific Beechcraft aeroplanes.

What it does: It scraps a 1967 requirement that owners of Beechcraft 19, 23, and 24 series aircraft had to modify the mounting of a radio noise filter (called an ADF noise suppressor capacitor) by September 1971.

Who it affects: Owners and operators of these specific Beechcraft aircraft models, though the cancellation removes an old obligation rather than imposing a new one.

Why it matters: The original safety deadline passed nearly 40 years ago, and the equipment in question is now obsolete. This cleanup removes an unnecessary regulatory burden from aircraft maintenance records.
