What it does

The FAA proposes to supersede Airworthiness Directive (AD) 2023-21-10, which applies to certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42-500 and ATR72-212A airplanes. AD 2023-21-10 requires 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 proposed AD would continue to require the actions in AD 2023-21-10 and would require 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 proposing this AD to address the unsafe condition on these products.
