There is a magic number associated with every airplane — a number referred to as time between overhauls, or TBO for short.
Piston Engines: Keeping Your Cylinders Happy
Key Takeaways:
- Time Between Overhauls (TBO) is a manufacturer's recommendation, often not met due to infrequent flying, with some experts advocating for condition-based maintenance over strict adherence.
- Maintaining optimal cylinder head temperatures (CHT) is crucial for engine longevity, involving careful mixture management (lean vs. rich of peak debate) and preventing rapid cooling or preignition.
- Regular engine monitoring, appropriate lubrication practices (oil type and changes), and consistent, proper flying (not just ground runs) are essential for maintaining engine health and potentially exceeding TBO.
