Aftermath: Too Much

Gemini Sparkle

Key Takeaways:

  • A Piper Super Cub crashed in Alaska due to severe overloading (640 lbs over gross weight), an extreme aft center of gravity, and aerodynamically compromising external loads like caribou antlers.
  • The incident highlights the distinct, often high-risk, operational practices in Alaskan bush flying where aircraft frequently operate beyond published limitations, prioritizing experience over strict adherence to regulations.
  • The pilot made a series of critical decisions, including a downwind takeoff on a short, rough strip with the heavily loaded and unstable aircraft, ultimately leading to a fatal loss of control shortly after liftoff.

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.
