at the owner's request immediately following the discovery of the failed cable.  The forward elevator cable in this aircraft was found to be extensively frayed in the same location as the failed cable.

             Since the original issue of this AD, applicable to other Beechcraft models, CASA has received reports of 5 more cables found to be unserviceable.  CASA has determined that this aircraft model may be fitted with the same of forward elevator control configuration.

             This AD requires an inspection or replacement of any forward elevator cable that has not been carried out during the period prior to the issue of the last maintenance release.  This inspection is required to preclude the unanticipated failure of the elevator flight control system which may result in loss of control of the aircraft.

             The manufacturer has recently published Instructions for Continuing Airworthiness (ICA) relating to the elevator control system.  Those ICA are considered satisfactory to ensure the failure of the elevator cable does not occur provided that the ICA is adhered to during the inspection process.
