## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Saab Model SAAB 2000 series airplanes. This proposal would require replacing the Abex alternating current (AC) electric motor with a new modified Abex AC electric motor having an improved fan. This proposal is prompted by reports indicating that the integrated hydraulic package (IHP) unit stopped functioning during flight because the fan on the AC electric motor came into contact with the housing of the motor due to inadequate clearance. The actions specified by the proposed AD are intended to prevent loss of IHP function that, if combined with other hydraulic system failures, could result in reduced controllability of the airplane.
