Commonwealth legislation
The Schedule entry records that airworthiness directive AD/G73/3 for Frakes (Grumman) G73 series aeroplanes has been superseded by AD/G73/21. It doesn’t state technical requirements itself — affected parties must consult AD/G73/21 for inspections, repairs and compliance times.
Owners, operators and maintainers of G73 aircraft (and CASA as the listing authority) are impacted: any costs and operational changes required by the operative AD fall to the aircraft operators. The suffix “NK” is shown but not explained in this entry.
