Aftermath: Too Much

Gemini Sparkle

Key Takeaways:

  • An Alaskan Piper Super Cub crashed due to severe overloading (640 lbs over gross weight) and an extreme aft center of gravity, exacerbated by external loads like caribou antlers, which critically compromised its flight performance.
  • Despite the challenging strip conditions and the aircraft's compromised state, the pilot chose to take off with a tailwind towards obstructions, later lamenting his decision.
  • The accident highlights the dangerous practice in Alaskan bush flying of routinely exceeding published aircraft limitations, often prioritizing perceived experience over safety regulations in remote environments.

The Piper Super Cub is essentially a J-3 Cub airframe equipped with a few space-age refinements like flaps and an electrical system, and powered by a 150 hp Lycoming — in some cases a 160 or 180 — in place of the original’s 40 hp Continental. Piper produced nearly 3,000 of them, many of which now live in Alaska. One of those came to grief in 2013 at the remote Tatitna Airport (8KA) in a way that incidentally sheds some light on how differently airplanes are used in Alaska than in the “Lower 48.”

In a summer 2009 photograph on the site airport-data.com, the airplane appears showroom clean. A row of aftermarket vortex generators is visible on the upper surface of the wings, which have squared-off Dakota Cub tips. The tires are normal 600s, and skis are installed between them.
