Airworthiness Directives; Boeing Model 737-600, 737-700, 737-800, 757-200, and 757-300 Series Airplanes

Resumen

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-600, 737- 700, 737-800, 757-200, and 757-300 series airplanes. This proposal would require replacing existing video distribution unit (VDU) connectors with new, improved connectors or new wire assemblies (jumpers), and performing related actions, as applicable. This action is necessary to prevent a short circuit in a VDU connector and consequent arcing and damage to wiring within the connector, which could result in damage to adjacent systems or structure and possible smoke or fire in the airplane cabin. This action is intended to address the identified unsafe condition.
