Airworthiness Directives; McDonnell Douglas Model DC-9-80 Series Airplanes and Model MD-88 Airplanes

This document corrects information in an existing airworthiness directive (AD) that applies to all McDonnell Douglas Model DC-9-80 series airplanes and Model MD-88 airplanes. That AD currently requires revisions to the Airplane Flight Manual (AFM) and installation of inspection aids on the wing upper surfaces. That AD also requires, among other actions, installation of an overwing heater blanket system or primary upper wing ice detection system, and installation of a heater protection panel or an equipment protection device on certain overwing heater blanket systems. This document corrects an incorrect paragraph reference. This correction is necessary to ensure that operators are aware of an incorrect paragraph reference in paragraph (d)(2)(ii)(A) of the existing AD.
