## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Beech Model 400, 400A, and MU-300-10 airplanes. This proposal would require installation of an improved adjustment mechanism on the flightcrew seats and replacement of the existing aluminum seat reinforcement assemblies with steel assemblies. This [[Page 27706]] proposal is prompted by reports of incomplete latching of the existing adjustment mechanism and cracked reinforcement assemblies, which could result in sudden shifting of a flightcrew seat. The actions specified by the proposed AD are intended to prevent such shifting of a flightcrew seat, which could impair the flightcrew's ability to control the airplane.
