Airwork: Time to Pull the Plug?

After 33 years, the engine in my 1976
Cessna Cardinal, with almost 450
hours passed TBO and 20 years since
it was overhauled, may have reached
retirement age.

Key Takeaways:

  • The author's aircraft engine, well past its recommended overhaul time but previously performing reliably, began experiencing intermittent rough running issues that proved difficult for mechanics to consistently diagnose.
  • Despite the engine's good "on-condition" performance history, mechanics, citing the engine's high time and safety/liability concerns, recommended an overhaul or replacement rather than attempting to fix an elusive problem.
  • The author faces a significant financial and personal dilemma, weighing the investment of $30,000-$40,000 from retirement savings for a new engine against the challenges of selling a non-airworthy aircraft in a depressed market, and ultimately questioning the overall cost-benefit of aircraft ownership.

Tom, I’ve got bad news for you,” Brian says when I answer the phone.

The phone call isn’t a surprise. I’ve expected the call every time my airplane was in the hands of a mechanic during the last year or so, but it isn’t welcome.
