Q: I’m considering buying a 2003 Socata Trinidad TB20 that has an extremely low time of just over 200 hours. A single owner purchased it new and obviously hasn’t flown it much.
It has a 250-hp Lycoming IO-540 engine. The cylinder heads were nickel coated in 2017 after an inspection found pitting on the original steel cylinders, no doubt because it sat for some time between flights. The plane has never missed an annual inspection, so it must have been run at least once a year.
Since the cylinder coating in 2017, the plane still hasn’t been flown much, but I’m told that it never sits for more than a month without being run by an airplane mechanic for some period of time as it is hangared in a place that has a service center.
What are the risks with this low time, but older infrequently used engine?[Read more…]
