Fuel sampling and trim runaways

This episode highlights two key safety topics for GA pilots: trim runaways and fuel contamination. We explore how to recognise the early signs of a trim runaway, the immediate actions pilots should take, and why staying ahead of the problem is critical. We then cover the fundamentals of correct fuel sampling, including common sources of contamination, how to take reliable samples, and what to do if the fuel doesn’t look right. With more pilots returning to the skies as the weather improves, this episode offers practical reminders to help keep every flight safe. More information on trim runaways and fuel contamination can be found on our website at: Safety Topics | UK Civil Aviation Authority.
