## Summary

This amendment proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Model A310 and Model A300 B4-600, A300 B4-600R, and A300 F4-600R (collectively called A300-600) series airplanes. This proposal would require replacement of the ejection jack on the ram air turbine (RAT). This action is necessary to prevent the ejection jack on the RAT from failing when the RAT is deployed at high airspeeds, leading to a loss of ability to properly restrain the movement of the RAT, possibly resulting in damage to the RAT itself and to other airplane components. In the event of an emergency, failure of the ejection jack on the RAT could also result in a reduction of hydraulic pressure or electrical power on the airplane. This action is intended to address the identified unsafe condition.
