Plain English Summary

3/10 complexity

Operators of all Gulfstream G.159 series aeroplanes must carry out a fluorescent‑dye non‑destructive inspection of the landing‑gear aluminium forgings per Gulfstream Customer Bulletin No.228B within 150 landings after 28 Dec 1989 (or within 150 landings since the last overhaul if later), then continue inspections under the G1 schedule. The AD prescribes the specific NDI method for Australia, limits operators’ choice of technique, and places inspection costs, downtime and any repairs on aircraft owners/operators.
