What  is  your  available  engine’s  tbo  ?

The TBO (Time Between Overhaul) is a measure defined by the OEM, Pratt & Whitney Canada (P&WC) in our case, that indicates the hours your asset can be used before it requires overhaul. While the basic TBO for PT6T-3B and PT6T-3DF engines is 4,000 hours, it varies for each model and can be higher or lower. For the PW206 and PW207 series engines, the overhaul interval varies between 3,500 hours and 4,000 hours, depending on the engine’s configuration. With a 5,000 hour Time Between Overhaul, the PT6C-67C engine has one of the highest TBOs for all P&WC helicopters engines. While these are the basic limits, operators can apply for TBO extensions with the OEM. They can therefore increase their fleet’s Time between overhaul if certain conditions are met. When planning your fleet composition, make sure to take the long-term impact of the TBO into consideration.
