First flight test of PT6A-135A upgrade STC

By Janice Wood · November 9, 2010 ·

Experimental flight testing of StandardAero’s planned PT6A-135A engine upgrade Supplemental Type Certificate (STC) was successfully conducted in September with a Cessna Caravan 208. The flight test occurred at Wipaire, Inc. in St. Paul, Minn. STC certification is expected in the first quarter of 2011 for Caravan 208 models and second quarter 2011 for Caravan 208B models pending FAA approval.

“We are excited about this new STC and the benefits it will provide to Caravan 208/208B operators,” said Manny Atwal, vice president, Turboprop Programs, StandardAero. “With improved efficiency in the air inlet ducting, operators will see increased engine horsepower and increased aircraft performance with rate of climb, cruise speed, fuel efficiency and landing performance.”

StandardAero’s PT6A-135A engine upgrade STC for the Cessna Caravan 208/208B gives operators an additional option besides repair or overhaul for their existing PT6A-114/114A engine. Operators will be able to replace their existing PT6A-114/114A engine with a factory new PT6A-135A engine with a simple firewall forward aircraft modification. Customers will be able to perform the PT6A-135A engine upgrade on an exchange basis in lieu of repairing or overhauling their PT6A-114/114A engine.
