AD/GENERAL/42 - Microphone/Compass Safe Distance - Modification - CANCELLED

What this does: This document cancels an old aircraft safety rule that required modifications to keep microphones stored at a safe distance from compasses to prevent magnetic interference.

Who it affects: Aircraft operators, pilots, and maintenance engineers who were previously required to comply with the 1968 microphone stowage separation rule.

Why it matters: The Civil Aviation Safety Authority determined that this decades-old requirement was no longer justified as a safety-of-flight issue under modern aviation regulations. Cancelling the directive removes an outdated compliance burden from the aviation industry.
