PT6 turboprop engine makes General Aviation history: 50,000th engine rolls off the Pratt & Whitney Production Line

LONGUEUIL, QUEBEC, December 2, 2020 – Pratt & Whitney, a division of Raytheon Technologies Corp. (NYSE: RTX), today announced that the 50,000th PT6 turboprop engine has rolled off the production line achieving an exceptional milestone in General Aviation. With the new PT6 E-Series™ engine now in full production, powering the Pilatus PC-12 NGX, the numbers continue to grow.

“From the first application more than 50 years ago, the now-iconic PT6 engine turns possibilities into realities for our customers around the world on more than 130 different applications today,” said Irene Makris, vice president, sales and marketing at Pratt & Whitney. “With each new model of engine developed and designed for a mission, platform, and customer in mind, our employees continue to build a more efficient, smarter engine with a shrinking environmental footprint– and they continue to rise to the challenge every day.”

The PT6 turboprop engine is the proven choice for demanding, high-cycle/high-power applications in single- and twin-engine aircraft for all kinds of missions and applications. The engine fleet’s current flying population is more than 25,000 units and it has accumulated more than 410 million flight hours and counting–that’s more flying time than anyone else in this segment.

Makris sees the 50,000-engine marker as the opportunity to pause and thank customers and employees for this remarkable accomplishment. It is a testament to the ongoing success of the engine and the innovation behind its ongoing evolution. The most recent example of this being the launch of the PT6 E-Series™ engine, the first the first turbine engine in the general aviation market to offer a dual-channel integrated electronic propeller and engine control.

“This production milestone is unmatched in the industry. It offers us another opportunity to celebrate the engine’s ongoing success as we continue exploring new horizons for even more flying possibilities,” Makris said. “The achievement sits as the collective cornerstone of Pratt & Whitney in General Aviation. With the PT6 E-Series™ engine now at the forefront, we remain committed to pushing innovation as we’ve been doing since the very beginning.”

The PT6 ran for the first time in 1960, entering service in 1964. Pratt & Whitney currently offers more than 70 PT6A models, ranging from 500 SHP to over 1,900 SHP. The PT6 E-Series, the latest addition to the PT6 line, was launched in October 2019 and powers the Pilatus PC-12NGX.

What is a Hot Section Inspection & Why It’s Important to PT6A Engine Longevity

The Pratt & Whitney PT6 engine has been in use since 1961 and has since logged more than 380 million flight hours, the equivalent of about 250,000 round-trips to the moon.   The most advanced PT6A engine family includes three power levels, “Small”, “Medium”, and “Large” that all have the advantage of turbine cooling, aerodynamic design, and advanced technologies in materials.  Keeping these engines running efficiently and safely wouldn’t be possible without a periodic Hot Section Inspection.

Why You NEED to Know EDD – Electrostatic Discharge Damage in the PT6A

Last month we disassembled and investigated a 3000 hour time since new PT6A-34AG engine with a #1 bearing failure that appears to be attributable to a phenomenon called: EDD! The damage from the failure combined with damage from the propeller sudden stoppage following the aircraft’s off airport landing has resulted in a BER; an engine that is “Beyond Economic Repair”!

The Sky Is No Longer The Limit

The Sky Id No Longer The LimitAs private aircraft piloting is becoming more accessible to a number of population segments, advances in experimental designs that support sustainable flying have also become more prominent. This is largely due to the fact that existing turbines and radial engines can not only be obtained to be modified, but they can also be combined with better body designs and alternative power sources to propel the engines.
