Unsafe Condition
Failed flight control modules (FCM) with P/N 65-44891-7 and S/N 8726 or greater can result in sluggish response of aileron, elevator, and rudder surfaces. Operation with one failed FCM could cause reduced controllability, while two failed FCMs could lead to loss of control.

Required Actions
Inspect to determine FCM serial numbers. Replace suspect FCMs (P/N 65-44891-7, S/N 8726+) with serviceable units (S/N <8726) or approved alternatives. Revise AFM with failure identification and flight procedures. Submit inspection findings to FAA. Replace failed FCMs before further flight.
