StandardAero gets FAA STC approval for PT6A-140 engine

StandardAero, with support from its in-house Organization Designation Authorization (ODA) delegation, has obtained a Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) approval for Pratt & Whitney Canada (P&WC) PT6A-140 engine upgrades on Cessna Caravan 208B aircraft.

The upgrade program includes the removal of P&WC’s PT6A-114/114A engine and replacement/installation of a P&WC PT6A-140 model engine.

Installation of this new STC provides numerous benefits to Cessna Caravan 208B aircraft operators.  The P&WC PT6A-140 model engine provides a 28-45% increase in shaft horsepower by replacing the existing P&WC PT6A-114/114A engine.  Other benefits to aircraft performance include reduced takeoff distance (under 1,200 foot ground roll) and up to a 40% improvement in the rate of aircraft climb (1,200+ feet/per minute).  These benefits will give operators enhanced safety margins for environmental factors, including flight in known icing conditions.

“These aircraft operators now have a choice for upgrading their engines and may also install the upgrade at their maintenance location of choice,” said Rob Higby, Vice President of Global Sales & Marketing for StandardAero Airlines & Fleets.  “Ultimately, this upgrade gives Cessna Caravan operators the performance benefits of a Grand Caravan EX without having to buy a new aircraft.”

This new STC/upgrade program is available immediately.


As a Pratt & Whitney Canada PT6A Designated Distributor and Overhaul Facility, StandardAero is now the only MRO provider that can offer both repair and engine upgrade solutions for P&WC PT6A-114/114A powered Cessna Caravan 208B operators.  In addition, StandardAero can provide enhanced warranty offerings that exceed basic OEM warranty benefits on new engines.
