## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes. This proposed AD would require replacing certain electrical panels with certain new panels. This proposed AD is prompted by a report of some loose wire terminations in the P50 panel that caused intermittent indications in the flight deck. We are proposing 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.
