## Summary

ODI has identified certain MCI coaches with powertrain configurations that may allow a driveshaft separated at the rearward universal joint to escape the guardian structure of the steerable tag axle and damage steering and braking components.The damaged components may increase the risk of a loss of vehicle control. The subject coaches include 806 model year 1992 through 2012 MCI D and E series motor coaches with steerable tag axles.This Preliminary Evaluation is being upgraded to an Engineering Analysis (EA12-007) to further study the alleged defect and to determine if a safety defect exists.
