## Summary

We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 747 series airplanes and certain Boeing Model 757- 200, -200PF, and -300 series airplanes. This proposed AD would require replacing the control switches of the forward, aft, and nose cargo doors of Model 747 airplanes; and would require replacing the control switches of cargo doors 1 and 2 of Model 757 airplanes. This proposed AD results from reports of problems associated with the uncommanded operation of cargo doors. We are proposing this AD to prevent injuries to persons and damage to the airplane and equipment.
