Covington Aircraft, a Pratt & Whitney Canada distributor and designated overhaul facility since 2009, recently expanded its approved capabilities to include maintenance, repair and overhaul on most PT6A engines. The company sells new P&WC PT6As and says it maintains an ample supply of rental engines to keep customers flying. Founded in 1972, Covington Aircraft still overhauls Pratt & Whitney R-985 and R-1340 radial piston engines at its Okmulgee, Okla. facility.
