The \"NK\" notation typically indicates the directive applies to aircraft registered in Papua New Guinea (a legacy of CASA's former role in that jurisdiction).\n\n**Why it matters:** Aircraft maintenance records must track the current status of all applicable ADs. When an AD is superseded, operators must comply with the newer version, not the old one. This document serves as a historical reference point showing the regulatory lineage of safety requirements for this aircraft type.\n\n**Key takeaway:** If you operate or maintain a Grumman G73 Mallard, you need to consult **AD/G73/21** (not this version) to ensure compliance with current airworthiness requirements."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":true,"description":"The entry explicitly records that AD/G73/7 has been superseded by AD/G73/21 (source: “AD/G73/7 Superseded by AD/G73/21 NK”), which means the prior directive’s obligations have been replaced.
