Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-120 series airplanes. This proposal would require installing three new vertical cargo nets in cargo-configured cabins. This action is necessary to prevent significant movement of cargo during operation, which could result in loss of control of the airplane or injury to the flightcrew. This action is intended to address the identified unsafe condition.
