(Aluminum) 20 gal each 40 total

The original Osborne tanks were developed by Brittain
Industries, which first offered tip tanks for Bonanzas back in
1959. These tanks were once available as a Beech factory
option. Osborne purchased Brittain in 1969. Aluminum halves
are drop-hammer die-formed and then welded together to
make each 20-gallon tank. The fuel filler is accessed through a
spring-loaded door in the outer top side of the tank. Strobes
and nav lights are included, as appropriate to the individual
aircraft. 

All of the Bonanzas receive a gross weight increase with the tip tanks. This varies from
model to model. Check the Gross Weight Increase Comparison chart. With the exception
of the A36s, installation of the tip tanks reverts the Bonanza to the Normal category. The
A36 models retain Utility category certification when the tanks are empty.
