Plain English Summary

3/10 complexity

This airworthiness directive mandates owners/operators of all Schweizer G‑164 (Ag‑Cat) series aeroplanes to carry out the actions in Schweizer G164 Service Bulletin No. 85, initially before 18 November 1989 and thereafter at intervals not exceeding 12 months. It was issued after reported corrosion/cracking of elevator pushrods (including one loss), so recurring inspections and corrective actions are required and costs/facility time fall to operators.
