Plain English Summary

3/10 complexity

This airworthiness directive requires owners/operators of CASA 212 series aeroplanes to follow CASA Service Bulletin SB 212-57-10—including recurring actions at 100‑hour intervals until a specified modification is completed—to detect and prevent cracking in inner flap fittings. It replaces voluntary maintenance choices with a mandatory, ongoing inspection/repair obligation, shifting compliance costs and operational burden to operators.
