This AD was prompted by the discovery of a rupture in the housing of one of the ram air turbine (RAT) ejection jacks installed as specified in the existing AD. We are issuing this AD to prevent rupture of the housing of the RAT ejection jack due to overpressure in the jack caused by overfilling the hydraulic fluid, and consequent failure of the RAT ejection jack. Failure of the ejection jack could result in a lack of hydraulic pressure or electrical power in an emergency.
