Description

The FAA is superseding Airworthiness Directive (AD) 2023-21-10, which applied to certain ATR-GIE Avions de Transport Régional Model ATR42-500 and ATR72-212A airplanes. The previous AD required inspection of the horizontal stabilizer's left- and right-hand leading edge lateral ribs, the box in between, the center box upper panel, and forward back-up fitting for discrepancies and corrective actions. The new AD expands applicability to additional airplanes and requires inspection of the horizontal stabilizer front spar web and center box internal area for discrepancies and corrective actions. This AD addresses unsafe conditions such as loose, missing, or incorrectly installed fasteners, composite delamination, and cracks in the horizontal stabilizer to ensure structural integrity of the airplane.
