Blackhawk Modifications, Inc. has announced a time between overhaul (TBO) baseline extension from 3,600 hours to 4,000 hours for the Cessna Caravan XP140 Engine Upgrade.
With this 400-hour TBO increase, the hot section inspection (HSI) interval is also extended from 1,800 hours to 2,000 hours.
Pratt & Whitney Canada (P&WC) announced in Service Information Letter (SIL) #PT6A-259 that these TBO and HSI extensions are retroactive, meaning that all existing PT6A-140 engines operating today can take advantage of the increases
The extended TBO and HSI intervals will allow Caravan operators to save on operating expenses with less frequent maintenance needed on the engine.
“We are pleased to see this customer-first, cost-effective business decision from Pratt & Whitney that directly benefits all existing and future Blackhawk XP140-powered Caravan operators,” said Jim Allmon, president and CEO of Blackhawk Modifications.
“Extending the base overhaul interval to 4,000 hours provides another compelling reason to replace aging PT6A-114A engines with the latest and greatest engine technology now available to the Caravan from Blackhawk.”
In addition to the extension, TBO harmonization is also offered for operators with a mixed fleet of PT6A-114/A and PT6A-140 engines.
Those with a valid P&WC-recommended TBO extension for PT6A-114/A engines may apply this recommendation to PT6A-140 engines in their fleet.
