The \"NK\" notation typically indicates the amendment status or applicability.\n\n**Who it affects:** Owners and operators of Frakes/Grumman G73 Mallard aircraft registered in Australia.\n\n**Why it matters:** While this particular directive is no longer in force, it forms part of the regulatory history showing how safety requirements for this aircraft type have evolved.
