(1) Model ATR42-500 airplanes, serial numbers (S/Ns) 1014, 1016 through 1019 inclusive, and 1201 through 1212 inclusive.

We are adopting a new airworthiness directive (AD) for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42-500 airplanes and Model ATR72-212A airplanes. This AD requires an inspection for routing attachments of electrical harness bundles and for wire damage, and corrective actions if necessary. This AD was prompted by reports of electrical harness bundle chafing with a window blinding panel in the fuselage due to missing routing attachments. We are issuing this AD to address the unsafe condition on these products.
Within 6 months or 500 flight hours after the effective date of this AD, whichever occurs first: Do a detailed inspection for missing brackets and damage (including but not limited to chafing and electrical shorting) to wire bundles of the Route 1M and Route 2M electrical harness, in accordance with the Accomplishment Instructions of ATR Service Bulletin ATR42-92-0033, dated May 3, 2017 (for Model ATR42-500 airplanes); or ATR Service Bulletin ATR72-92-1044, dated May 3, 2017 (for Model ATR72-212A airplanes); as applicable.
If the inspection required by paragraph (g) of this AD reveals that any bracket is missing or any wire is damaged: Before further flight, do applicable corrective actions, in accordance with the Accomplishment Instructions of ATR Service Bulletin ATR42-92-0033, dated May 3, 2017 (for Model ATR42-500 airplanes); or ATR Service Bulletin ATR72-92-1044, dated May 3, 2017 (for Model ATR72-212A airplanes); as applicable. Where ATR Service Bulletin ATR42-92-0033, dated May 3, 2017; or ATR Service Bulletin ATR72-92-1044, dated May 3, 2017; specifies to contact ATR—GIE Avions de Transport Régional for appropriate action: Before further flight, accomplish corrective actions in accordance with the procedures specified in paragraph (i)(2) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
