Engine Troubleshooting in Double Time

With my Piper Arrow loaded to its full capacity of four people (including me, two journalists, and an environmental executive director), the Lycoming IO-360 engine decided it no longer wanted to participate at full power.

Key Takeaways:

  • An in-flight engine failure forced a pilot to make an immediate return to the departure airport with passengers, where a severe problem with cylinder #3 was diagnosed.
  • Despite initial difficulties finding maintenance at the remote airport, the pilot received significant support and kindness from various individuals, including mechanics, FBO staff, and fellow pilots, turning a serious incident into a manageable ordeal.
  • The issue was eventually resolved after nearly two weeks, with the cause determined to be a momentary fuel injector blockage, underscoring the positive impact of community and assistance during an unexpected mechanical breakdown.

Knock on wood: I’ve been fortunate not to have experienced an in-flight mechanical event of any consequence with any of the airplanes I’ve owned. Until recently. And despite the seriousness of the event, the aftermath included positive aspects.

With my Piper Arrow loaded to its full capacity of four people (including me, two journalists, and an environmental executive director), the Lycoming IO-360 engine decided it no longer wanted to participate at full power. Instead, the engine protested by shaking the airplane with a pronounced vibration barely five minutes into the climb out. As though to scold me, the digits of the engine monitor display began to flash high EGT and high CHT numbers on the number-3 cylinder. I cringed.
