It requires aircraft owners and operators to take specific actions (inspections, repairs, modifications) to address unsafe conditions.\n\n**What this specific document shows:** This is essentially a **placeholder or reference entry** indicating that AD/G73/12 has been replaced by a newer directive, AD/G73/21. The \"NK\" likely indicates the classification or source (possibly \"Non-Kit\" or similar internal coding).\n\n**Who it affects:** Owners and operators of Frakes/Grumman G73 Mallard aircraft registered in Australia.\n\n**Why it matters:** Pilots and maintenance engineers need to know which ADs are currently in force. This document tells them **not to use this old version** — they must follow AD/G73/21 instead.
