1 of 8 SERVICE BULLETIN MANDATORY SB 28-3967 Issued: June, 2009 The export of these commodities, technology or software are subject to the U.S. Export Administration Regulations. Diversion contrary to U.S. law is prohibited. For guidance on export control requirements, contact the Commerce Department's Bureau of Export Administration at http://www.bis.doc.gov. Hawker Beechcraft Corporation (HBC) 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, inspection and modifications that could affect safety or crashworthiness. HBC 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, HBC 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 available on the web at http://pubs.hawkerbeechcraft.com and mailed to: (a) Owners of record on the FAA Aircraft Registration Branch List and the HBC Safety of Flight Information (SOFI) List. (b) Those having a publications subscription. Information on Safety of Flight Information (SOFI) or subscription can be obtained through the Hawker Beechcraft Corporation Technical Manual Distribution Center (TMDC). As Mandatory Service Bulletins and Service Bulletins are issued, the Service Bulletin Master Index will be updated and available online at http://pubs.hawkerbeechcraft.com. Warranty will be allowed only when specifically defined in the Service Bulletin and in accordance with HBC Warranty Policy. Unless otherwise designated, HBC Mandatory Service Bulletins, Service Bulletins and HBC Kits are approved for installation on HBC airplanes in original or HBC modified configurations only. HBC Mandatory Service Bulletins, Service Bulletins and Kits may not be compatible with airplanes modified by STC installations or modifications other than HBC approved kits. Beechcraft 1. Planning Information A. Effectivity (1) Airplanes Model G36 Bonanza, Serials E-3630, E-3636 through E-3817, E-3819 through E-3834, E-3836 through E-3887, E-3889 through E-3896, E-3898 and E-3899. If you are no longer in possession of the airplane, please forward this information to the present owner. (2) Spares None. B. Reason Owners / operators shall not take off if fuel odor is present in the cockpit or evidence of fluid is present on the floor forward of the pilot’s seat. Investigate fluids in the inspection area to ensure no fuel has leaked into the cockpit. If either condition is noted during flight, land as soon as practical at a suitable airport. If erratic instrument readings are encountered, follow procedures listed in the Model G36 Bonanza Pilot’s Operating Handbook/ Airplane Flight Manual, Section 3 Emergency Procedures and Section 3A Abnormal Procedures. This Service Bulletin is being issued to inspect for and, if found, correct an improper installation of the P60 / J60 electrical connector, associated wiring, and fuel line. Contact between the fuel line and electrical components may cause damage to the fuel line, up to and including leakage. Safety Communiqué 303 was issued on this subject in April of 2009. TITLE: FUEL - INSPECTION FOR CHAFING OF ELECTRICAL CONNECTOR AND ASSOCIATED WIRING ON FUEL LINE SERVICE BULLETIN Issued: June, 2009 SB 28-3967 2 of 8 MANDATORY C. Description An inspection is performed on the P60 / J60 electrical connector [part numbers (P/N) 207019-1 / 207020-1, respectively], associated wiring, and fuel line (P/N 36-920001-13) to verify that proper clearance exists between the components and that the protective insulating tube is installed on the proper section of the fuel line. If chafing is found, damaged components are replaced and positive clearance is established. D. Compliance An Airworthiness Directive will be requested on the matter covered by this Service Bulletin. Hawker Beechcraft Corporation (HBC) considers this to be a Mandatory Service Bulletin. It must be accomplished within the next 10 flight hours or six (6) calendar months from receipt of this Service Bulletin, whichever occurs first. E. Approval The engineering data contained in this Service Bulletin is FAA approved. Prior to accomplishment, owners / operators of airplanes registered in countries other than the United States shall consult with their local Aviation Regulatory Authority. Incorporation of this Service Bulletin restores the airplane to original type design. F. Manpower The following information is for planning purposes only: Estimated man-hours to perform inspection: 1 hour. Estimated man-hours to install chafe protection: 2 hours. Estimated additional man-hours to install new fuel line, if required: 3 hours. Suggested number of men to perform inspection / maintenance: 1 man. The above is an estimate based on experienced, properly equipped personnel complying with this Service Bulletin. Occasionally, after work has started, conditions may be found that could result in additional man- hours. G. Weight and Balance None. H. Electrical Load Data Not changed.
