Plain English Summary

3/10 complexity

This Airworthiness Directive requires operators of ATR 42-200 and -300 aeroplanes fitted with main landing gear side brace lower arms (part numbers GA 62045, 62045-1, GA 62045-2) to carry out the inspections and corrective actions set out in DGAC AD 91-033-038(B) R2 and the referenced ATR Service Bulletin (ATR42-32-0036 Rev 3). It takes effect on 2 August 2007.

Mechanically, it compels inspections, repairs or replacement to prevent side‑brace failure and landing‑gear collapse. Aircraft operators bear the compliance costs and must follow the externally specified DGAC/EASA‑approved procedures; CASA enforces the directive.
