Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 777-200 and -300 series airplanes. This proposal would require replacing existing ceiling and sidewall light connectors in the passenger cabin with new connectors, and follow-on actions. This action is necessary to prevent overheating of the light connectors, which could result in smoke and a possible fire in the passenger cabin. This action is intended to address the identified unsafe condition.
