Abstract
We are adopting a new airworthiness directive (AD) for certain Airbus Model A310 series airplanes. This AD was prompted by a report of an electrical arc and a hydraulic haze in the wheel bay of the left- hand main landing gear (MLG), possibly resulting from chafing between a hydraulic high pressure hose and electrical wiring of the green electrical motor pump (EMP). This AD requires modification of the electrical routing and replacement of the union elbows. We are issuing this AD to prevent chafing of hydraulic pressure hoses and electrical wiring of the green EMPs, which, in combination with a system failure, could cause an uncontrolled and undetected fire in the MLG bay.
