Diversion contrary to U.S. law is prohibited. For guidance on export control requirements, contact the Commerce Department’s Bureau of Export Administration at 202-482-4811 or at www.bxa.doc.gov. Raytheon Aircraft Company (RAC) issues Service Information for the benefit of owners and fixed base operators in the form of two classes of Service Bulletins. The first class, Mandatory Service Bulletins (red border) includes changes, inspections and modifications that could affect safety or crashworthiness. RAC also issues Service Bulletins with no red border which are designated as either recommended or optional in the compliance section within the bulletin. In the case of recommended Service Bulletins, RAC feels the changes, modifications, improvements or inspections will benefit the owner/operator and although highly recommended, Recommended Service Bulletins are not considered mandatory at the time of issuance. In the case of Optional Service Bulletins, compliance with the changes, modifications, improvements or inspections is at the owner/operator’s discretion. Both classes are mailed to: (a) RAC Authorized Service Centers. (b) Owners of record on the FAA Aircraft Registration Branch List and the RAC International Owner Notification/Registration Service List. (c) Those having a publications subscription. Information on Owner Notification Service or subscription can be obtained through any RAC Authorized Service Center. As Mandatory Service Bulletins and Service Bulletins are issued, temporary notification in the Service Bulletin Master Index should be made until the index is revised. Warranty will be allowed only when specifically defined in the Service Bulletin and in accordance with the RAC Warranty Policy. Unless otherwise designated, RAC Mandatory Service Bulletins, Service Bulletins and RAC Kits are approved for installation on RAC airplanes in original or RAC modified configurations only. RAC Mandatory Service Bulletins, Service Bulletins and Kits may not be compatible with airplanes modified by STC installations or modifications other than RAC approved kits. Beechcraft 1. Planning Information A.

Reason This Service Bulletin is being issued to inspect for P/N 002-440010-19 rudder cable pulley bracket that may have an elongated, misdrilled hole. An elongated hole may allow the pulley guard pin to shift in position and possibly cause inadequate cable guarding. During control system maintenance, inadequate cable guarding could allow displacement of the control cables. C. Description The P/N 002-440010-19 pulley bracket is inspected for damage in the form of elongated holes from improper drilling. If elongated holes are found, replace the existing P/N NAS427K11 pulley guard pin with a P/N MS20392-2C29 clevis pin, NAS1149F0332P washer and MS24665-132 cotter pin. Verify the rudder control cable is routed correctly under the pin. D. Compliance Raytheon Aircraft Company recommends that this Service Bulletin be accomplished at the next scheduled inspection.
