## Summary

We propose to supersede Airworthiness Directive (AD) 2006-07- 26, which applies to all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 airplanes. AD 2006-07-26 requires a one-time inspection to detect discrepancies (e.g., cracking, loose/sheared fasteners, distortion) of the upper skin and rib feet of the outer wing boxes, and repair if necessary. Since we issued AD 2006-07-26, we have received reports of cracking in these same areas on other Model ATR42 airplanes. This proposed AD would require repetitive inspections to detect discrepancies of the upper skin and rib feet of the outer wing boxes, and repair if necessary. We are proposing this AD to address the unsafe condition on these products.
