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:

  • The author experienced a critical in-flight engine failure with passengers aboard but safely returned the Piper Arrow to the departure airport.
  • Diagnosing and repairing the destroyed cylinder presented challenges due to the airport's lack of on-site maintenance and part availability, but was ultimately resolved by dedicated A&P mechanics.
  • Throughout the ordeal, the author encountered remarkable kindness and hospitality from various individuals, including airport staff, fellow pilots, and mechanics, which significantly eased the stressful situation.

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.
