Airworthiness Directives; McDonnell Douglas Model MD-11 Series Airplanes Equipped With Pratt & Whitney Model PW4400 Series Engines

This amendment supersedes an existing airworthiness directive (AD), applicable to all McDonnell Douglas Model MD-11 series airplanes equipped with Pratt & Whitney Model PW4400 series engines, that currently requires revising the Airplane Flight Manual (AFM) to advise the flight crew of applicable operational limits. This amendment corrects a typographical error in one paragraph of the existing AD that resulted in a reference to an incorrect engine fan blade which is not subject to the requirements of that paragraph. The actions specified in this AD are intended to ensure that the flight crew is informed of applicable limitations in airplane performance, and to prevent reduced acceleration and climb performance relative to performance data in the AFM, which could result in the airplane overrunning the end of the runway during takeoff or landing, or impacting obstacles or terrain. This action is intended to address the identified unsafe condition.
