Alaskan S.T.C. & Modification
When flying in Alaska, it does not take long to realize that all airplanes
are not equal. Some airplanes perform better then other like
airplanes. The difference sometimes is performance modifications.
Whether you are looking to shorten your landings and takeoffs
or maybe just improve your over all performance call Stoddards to
see where to start. We are currently working with several
Alaskan Facilities that offer S.T.C. installation & modifications
to help improve performance & enhance light aircraft maneuverability.
Here is just a sample of some of the more popular modifications;
Listed below, are some of the more popular modifications
