## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 757-200, 200CB, and -200PF; and 767-200, -300, and -300F series airplanes. This proposal would require modification of the right main landing gear and auto-speedbrake control system to provide an air/ground signal to the system. This action is necessary to prevent uncommanded deployment of the auto-speedbrake spoilers during flight, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
