Cessna 180/185 Skywagon

Contents[Hide]

Arguably the standard by which backcountry utility is measured, the venerable Cessna Skywagon has few peers in the 4-seat class. First introduced in 1953, the model 180 was the next generation in airframe and powerplant performance, improving upon the 170 series with more aerodynamic flush riveting, trimmable stabilator, square tail surfaces, a 470 cubic inch six-cylinder engine running at 220hp, a constant speed propeller, and overall greater load carrying capacity.

Nowadays, the list of modifications is extensive, making what is already a great backcountry aircraft even better. Here's a list of backcountry-oriented modifications that are approved by Supplemental Type Certificate (STC):

Suggest other valuable backcountry-oriented mods for this aircraft. It is very helpful to have information about the STC number and the website of the STC holder, if possible.

There's a forum topic underway about this.
