FAQs

  • An engine overhaul is a complete rebuild of your aircraft engine to restore it to like-new condition. It includes disassembly, cleaning, inspection, replacement of worn parts, reassembly, and full testing.

  • Most engines reach Time Between Overhaul (TBO) hours set by the manufacturer. However, excessive oil use, metal in the filter, power loss, or rough running are also signs it’s time.
