You are probably correct, Bill. Chris asked about the aerodynamics, but
it probably reduced the number of internal ribs.

I'd bet they are structural. Cheaper/easier than internal ribs, of
which I'll bet it has fewer.

Thanks for those ideas and pictures, Jim. And why was the rudder
ribbed? Was it only for strength, or did it produce its own vortices
and increase the rudder's effectiveness?

Apparently the sky divers' Twin Otter is undergoing maintenance, so
they brought in a replacement today. This is Serial Number 66,
from 1966.

The DeHavilland Twin Otter is loved and respected for its abilities
and its handling. To understand how this was achieved, one must
look at the details that DeHavilland worked into the design. An
example pictured here are the vortex generators that energize the
airflow in the corner between the fin and stabilizer to increase
the response of the rudder and elevator.
