PMA Engine Controls eligible for installation on Beechcraft aircraft. The applicable controls that are subject to this ICA are shown in Table 1. For all items not related to the installation of the McFarlane Aviation, Inc. Engine Controls, refer to the basic airplane model service and parts manuals. Table 1 - Part Number Listing McFarlane P/N Description MC35-944046-7 CONTROL, Throttle MCVA35-944046-7 CONTROL, Throttle, Vernier Assist MC35-944048-1 CONTROL, Propeller MC35-944048-7 CONTROL, Propeller MC35-944054-7 CONTROL, Mixture MC35-944054-9 CONTROL, Mixture MC36-380084-3 CONTROL, Throttle MC36-380084-5 CONTROL, Mixture MC36-380084-7 CONTROL, Propeller SYSTEM DESCRIPTION Beechcraft Bonanza aircraft utilize Vernier and quadrant style engine controls. These controls are mounted to the instrument panel between the pilot and co-pilot, routed through the firewall into the engine bay, and ultimately secured to the throttle, mixture, or propeller valve as required. The Beechcraft Bonanza aircraft subject to this ICA utilize two (2) half balls to create the seal around the engine control conduit at the firewall and inserted into the mounting flange and grommet, as shown in Figure 1. High temperature clamps are also utilized for the routing of the engine control. The McFarlane series of controls do not have the same outer diameter conduit as the TC’d assemblies. The half balls and clamps attached on the outer diameter of the conduit; therefore, the use of a McFarlane engine control will require replacement with components of the appropriate size in original locations. Figure 1- Control Installation through Firewall SPECIAL OPERATING INFORMATION The control and operation of the engine does not change with the installation of the engine control and the provided installation hardware; see applicable aircraft manufacturer/model Service Manual for the operational control of this system. PART REMOVAL, REPLACEMENT, AND SERVICE INFORMATION After removing the Beechcraft engine control, remove the old half ball (P/N 112413-8) from the grommet in the firewall seal and the mounting clamps (P/N: MS21919WDG6 & PP561DS4), as shown in Figure 1. When installing the McFarlane engine control, install the McFarlane half ball (P/N: 7391- 0.300) into the firewall grommet to ensure a tight seal around the conduit. Use the supplied high temperature clamps (P/N: MS21919WCJ5) when routing the new McFarlane engine control to the appropriate connection point, per the applicable Beechcraft Model Service Manual. The McFarlane provided installation components utilize the same mating hardware (bolts, nuts, washers, etc) for installation. Refer to the applicable Beechcraft Model Service Manual for installation/maintenance instructions and the applicable Beechcraft Illustrated Parts Catalog for component part numbers.
