The time between overhauls (TBO) of airplane engines is calculated during the manufacturer’s engineering process in order to ensure an aircraft performs its best even after long hours of operation. It’s a critical moment in its existence that will determine future performance so overhauls should not be taken lightly, and neither should TBO since it determines just when and what parts in the engine need to be repaired or refurbished. When these parameters are followed safety is enhanced and the lifespan of an engine can be prolonged. JSA has been managing engine overhauls for over 3 decades, helping aircraft stay safe with our FAA-certified parts. We’re honored to help our clients continue to soar the sky by keeping tabs of their TBO while safely prolonging their flight time.
