## Summary

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Lockheed Model 382 series airplanes, that currently requires a revision to the Airplane Flight Manual to require takeoff operation in accordance with revised performance data. That AD also requires installation of certain valve housings for the propeller governor on the outboard engines. This proposal would revise the applicability of the existing AD to remove certain airplanes. This proposal also would revise references to a certain replacement part number of a valve housing. The actions specified by the proposed AD are intended to ensure that the airplane maintains adequate thrust decay characteristics in the event of critical engine failure during takeoff.
