Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A300-600 series airplanes. This proposal would require modification of certain electrical looms of the nose and main landing gear and modification of the rotor shaft attachment of the nose and main landing gear tachometers. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent erratic operation of the wheel tachometers, which could result in degradation of the braking performance, and possible increased landing roll.
