Excessive wear in the door slide may result in the door becoming detached from the aircraft in flight, with potentially catastrophic results.Amdt 1 of this AD clarified and extended the compliance interval to 110 hours to allow operators to align the inspections with their periodical maintenance schedule.Amdt 2 of this AD was issued following an in-flight door separation, to update the service bulletin to remove any ambiguities that could have existed in the previous revision to the referenced service bulletin. It also provided an improved inspection method and a minor design change to the cargo door slide (inclusion of slide backing plate, castellated nut and split pin).Amdt 3 of this AD was issued to incorporate the requirements of the updated SB-GA8-2005-23 Issue 7. These included revised inspections of the door mechanism, the installation of a physical stop to the forward cargo door slide and rework the door slider to suit the track stop. Depending on aircraft configuration, the inspections may result in the rework of the door mechanism pivot, the upgrade of the door operating rod or fitting a door handle with an integral stop.Amdt 4 of this AD is issued to give legal effect to the service bulletin of the manufacturer’s (SB-GA8-2005-23) that improves clarity of the requirements and aligns FAA AD requirements. Compliance Table 2 of SB-GA8-2005-23 has been updated and the amendments to this AD reflect these changes. |\n\n![Signature of CASA delegate](image.001.jpeg)\n\nDavid Punshon \nDelegate of the Civil Aviation Safety Authority\n\n26 April 2024","sortOrder":0},{"sectionNumber":"AD/GA8/3 Amdt 4","sectionType":"part","heading":"AD/GA8/3 Amdt 4","content":"## AD/GA8/3 Amdt 4","sortOrder":1},{"sectionNumber":"Forward Cargo Door Slide","sectionType":"part","heading":"Forward Cargo Door Slide","content":"## Forward Cargo Door Slide","sortOrder":2},{"sectionNumber":"10/2024","sectionType":"part","heading":"10/2024","content":"## 10/2024","sortOrder":3}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":false,"description":"The legislation maintains its original narrow scope — addressing a specific mechanical defect in a specific aircraft type.
