## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes. This AD requires replacing certain electrical panels with certain new panels. This AD results from a report of some loose wire terminations in the P50 panel that caused intermittent indications in the flight deck. We are issuing this AD to prevent intermittent indications in the flight deck, incorrect circuitry operation in the panels, and airplane system malfunctions that may adversely affect the alternate flaps, alternate gear extension, and fire extinguishing.
