Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport Regional Model ATR72 airplanes. This proposed AD was prompted by occurrences of smoke in the flight deck and flap extension difficulties due to wire chafing on the electrical harness under a certain panel. This proposed AD would require modifying the clamp installation of the electrical routing on a certain rib of the left- and right-hand side of the wing rear spars, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
