Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes

Riepilogo

The FAA is revising a notice of proposed rulemaking (NPRM) to supersede Airworthiness Directive (AD) 2021-17-02, which applies to all ATR--GIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes. This action revises the NPRM by proposing additional modification of the affected wiring for certain airplanes. The FAA is proposing this AD to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, the FAA is requesting comments on this SNPRM.
