Part 1: Cessna 172 Skyhawk Avionics

Repurposing serviceable material to fly again has always been a thing with GA owners.

Key Takeaways:

  • General aviation (GA) aircraft owners exemplify a "reduce, reuse, recycle" approach, often repurposing parts to maintain and upgrade their planes.
  • The article details an instrument panel upgrade for Corey Sampson's 1966 Cessna 172H, primarily using "used serviceable material" (USM) avionics acquired from a fellow pilot's recently upgraded Piper Saratoga.
  • While integrating these USM components along with some new ones (Garmin G5s), the project faces an unexpected challenge due to Garmin discontinuing display repairs for one of the key repurposed units, the GNS 430.

There comes a time when social norms fall out of and then back into favor. Take, for example, recycling. In the early days of frontier America, folks had to make do with what they had. Neighbors helped each other and reciprocated when the circumstances warranted. What was once one person’s old barn became another’s two-wheeled cart, and so forth.

In the manufacturing boom of the Industrial Revolution, inexpensive goods flooded the market, and advertisers beckoned us to drop the old and replace it with the new. This seemed to work well until the 1970s when certain people despaired over the landfills filling up, and a new age of convenient curbside recycling emerged.
