## Abstract

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2000-07-51 that was sent previously to all known U.S. owners and operators of McDonnell Douglas Model 717-200 series airplanes by individual notices. This AD requires coiling and stowing of electrical wires between the glareshield control panel and the Integrated Standby Instrument System; and revising the abnormal procedures of the Procedures section of the Airplane Flight Manual to include procedures for identifying and pulling certain circuit breakers if the altimeter Captain's Primary Flight Display (PFD) data become unreliable. This action is prompted by a report of two incidents in which an intermittent loss of altitude data occurred simultaneously on the Captain's PFD, First Officer's PFD, and the Integrated Standby Instrument System (ISIS) altitude display due to a voltage drop in the power distribution control unit. The actions specified by this AD are intended to prevent loss of all altitude information and subsequent essential navigation data for continued safe flight and landing.
