Airworthiness Directives; McDonnell Douglas Model MD-90-30 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-90-30 series airplanes, that requires an inspection of the wiring in the left-hand tunnel area of the forward cargo compartment for evidence of chafing, and repair, if necessary. The actions specified by this AD are intended to prevent such chafing, which could result in subsequent shorting to structure, and consequent smoke and possible fire in the airplane. This action is intended to address the identified unsafe condition.
