Airworthiness Directive · Amendment 39-9951 · Lockheed Model 382 Series Airplanes
Lockheed Model 382 Series Airplanes
Model 382, 382E, and 382G series airplanes; equipped with a servo-type valve housing assembly having part number 714325-3 or -7 installed on any outboard engine; certificated in any category.
This amendment supersedes 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 amendment revises the applicability of the existing AD to remove certain airplanes. This amendment also revises references to a certain replacement part number of a valve housing. The actions specified by this AD are intended to ensure that the airplane maintains adequate thrust decay characteristics in the event of critical engine failure during takeoff.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
