AD 2026-16-07: ATR-GIE Avions de Transport Régional Airplanes

What the FAA requires

The FAA is superseding Airworthiness Directive (AD) 2023-21- 10, which applied to certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 and ATR72-212A airplanes. AD 2023-21-10 required an inspection of the horizontal stabilizer (HS) left- and right-hand leading edge lateral ribs, the box in between, the center box upper panel, and HS forward back-up fitting for discrepancies and applicable corrective action. Since the FAA issued AD 2023-21-10, it was determined that additional airplanes are affected and additional areas must be inspected. This AD continues to require the actions in AD 2023-21-10 and requires expanding the applicability and inspecting the HS front spar web and center box internal area for discrepancies and accomplishing applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
