Commonwealth legislation
This Act has been repealed and is no longer in force. It is retained for historical reference.
What this document does This officially cancels an old aviation safety rule (Airworthiness Directive 46) that required aircraft fuel gauges to be calibrated and clearly labeled (placarded).
Background The original rule was issued in 1972 to ensure pilots could read fuel levels accurately. However, modern aircraft are now built to design standards that automatically include these safety features during manufacturing, making the old rule redundant.
Who is affected Aircraft operators, maintenance engineers, and aviation businesses that previously had to comply with this specific calibration requirement.
Practical impact Operators no longer need to follow this directive or keep records showing compliance with it. The safety outcomes are now guaranteed by the aircraft's type certification standards instead of this separate operational rule.
