Beechcraft Bonanza

 

 

 

If you own a Bonanza, certainly you will be interested in what Wing Tip Tanks can do for you. Not only extended range but a gross weight allowance increase as well. Even on a short flight, point A to point B and returning without having to take precious time to refuel at point B. Not to mention the fuel savings when topping off with low priced fuel. Increased engine and airframe life due to fewer take offs and landings while not having to stop for fuel.

J. L. Osborne, Inc. formerly Brittain Industries, pioneered the development of wing tip tanks for civilian aircraft many years ago. Completely developing and redesigning the aluminum wing tip tank (20 gallons each) for the Bonanza, Navion, and Twin Navion, also the Single and Twin Piper Comanche's (15 gallon each). The 20-gallon wing tip tank is streamlined and smooth, with recessed Nav/Strobe lights, a flush filler and concealed drain. By means of drop hammer dies, the shells are formed of heat treated aluminum which is hardened to resist dents and distortion. The tank is assembled with flush welds, eliminating any raw edges or flanges protruding into the line of flight. We consider this tank aesthetically and aerodynamically outstanding. Together with this Tip Tank design, several installation hardware kits for different models make system installation practical.

DIRECT FEED SYSTEM

Salient features of the installation are simplicity of the mounting of the tank which requires no rework of the wing whatsoever. Fuel lines are readily routed through the existing rib holes in the wind structure. The fuel system being a direct feed, consisting of a manually operated five-position selector valve, including a Tip Tank “cross-feed” capability. A separate selector valve system is available for earlier models, working in conjunction with the factory selector valve system.


TRANSFER SYSTEM

Fuel lines are readily routed forward of the main wing spar connecting to a Transfer Pump/Flow Switch Assembly. The Transfer Pump/Flow Switch Assembly is located near the forward wing inspection cover, accommodating pump filter installation ease, maintenance, etc.. Other options include manual turn off when a desired amount of fuel has been transferred. After the Tip Tank fuel transfer is initiated (tip transfer pump) tip fuel enters the corresponding main tank through its' factory metal (bladder) inspection cover; leaving no fuel line installation holes in the main tank bladder. This transfer system transfers fuel by an electric pump turning off automatically when Tip Tanks empty.
