Blackhawk Scores with 20th XP140 Caravan Engine Upgrade
Less than a year after receiving its STC, Blackhawk has been highly successful with its engine-upgrade program.

Waco, Texas-based Blackhawk Modifications has been busy. Less than a year after receiving FAA approval of its Cessna Caravan XP140 New Engine+ engine upgrade STC, the company has completed its 20th installation. The upgrade replaces the existing 675-shp Pratt & Whitney Canada PT6A-114A turboprop with a more powerful (867-shp) and updated PT6A-140. Blackhawk made the announcement of the latest installation today at EAA AirVenture in Oshkosh.
