For years, the U.S. Air Force’s 318th Special Operations Squadron’s small PC-12 and C-145A aircraft supported secretive operations across five continents.
THE PT6 ENGINE MILESTONES
It’s the remarkable story of a remarkable engine. With more than 51,000 engines delivered to power some 130 different applications, the PT6 engine can tell quite a story of creativity and transformation. While we had a lot to choose from, we’ve put together a list of milestones for the engine as we mark its golden anniversary.
1957 – P&WC assembled a team of 12 talented young engineers after studies showed a market opportunity for 500 shp (shaft horsepower) class turboprop engines in the aircraft market then powered by piston engines. P&WC saw an opportunity to channel some of the profits from its piston engine spare parts business towards the development of gas turbine engines smaller than those made by its U.S. parent.
1963 – It’s what our celebration is all about. In December 1963, P&WC shipped the first PT6 production engine, the PT6A-6, to Beech Aircraft Company for its Beech 87, which later became the King Air. The PT6A-6 was a highly innovative gas turbine that represented a significant advance in technology from the traditional piston-driven engines used to power small aircraft. Gas turbines have a higher power to weight ratio than piston engines.
1967 – Piper’s PA-31 Navajo took its first flight powered by PT6A-20s. Piper had enjoyed enormous success building light aircraft since the 1930s, but it took P&WC years of effort to get Piper to adopt turbine engines and move away from their traditional reliance on piston-driven engines.
1968 – P&WC’s ST6L73 engine (a derivative of the PT6A without the gearbox second stage) entered into service as an auxiliary power unit (APU) for the Lockheed L1011 airliner.
1968 – Bell Helicopter placed its initial order for P&WC’s first turboshaft, the PT6T Twin-Pac® engine
1970 – P&WC’s PT6T Twin Pac® entered into service. It is two engines coupled in a single package to power medium-sized, twin-engine helicopters.
1970 – The United States Military ordered 294 Bell 212s under the designation UH-1N equipped with PT6T Twin-Pac® turboshaft engines. Delivery also began in 1970.
1973 – The second-stage power turbine was introduced on the PT6A-41. This was a step change in engine power and efficiency.
1979 – An Air Tractor agricultural aircraft is powered by a PT6A engine and flies to the National Agricultural Aviation Association convention in Las Vegas – the first time such a combination was displayed in public.

The ESP plan is a simple, cost-effective pay-per-hour engine coverage program that provides long-term costs and ensures a planned and preventative approach to maintenance. Being launched are: ESPecially for Your PT6 engine, which provides the first 400 hours of coverage for free to customers of new PT6A engine-powered aircraft; and an enhancement to P&WC’s current ESP plan offering, which enables customers to apply their ESP plan investment toward a new engine of the same model or a new engine conversion at time of overhaul.
“We continue to push ourselves to think outside of the box – about how we best serve our customers as well as deliver the greatest value and return on investment,” said Satheeshkumar Kumarasingam, Vice President of Commercial Services. “We’ve proven the bottom-line value of the ESP plan to thousands of customers as a unique solution that delivers a planned approach to OEM-backed engine maintenance. And we continue to innovate our maintenance coverage options with the launch of new and enhanced programs. Today’s announcement is a testament to the program’s ongoing evolution in delivering comprehensive pay-per-hour coverage.”
ESPecially for Your PT6 engine plan: First 400-hours of coverage at no cost
This past July, P&WC introduced the ESPecially for Your PT6 engine plan to aircraft OEMs as a way to support new aircraft sales and deliver optimal value to customers of new PT6A engine-powered aircraft. The plan includes P&WC’s world class ESP program with the first 400 hours of engine coverage at no cost to customers, representing a value of up to $50,000 per engine toward future maintenance. Additionally, after the first 400 hours of no-cost coverage customers will receive a reduced ESP plan rate until their first overhaul.
“In three months since we launched ESPecially for Your PT6 engine plan, the enrollment in the program has been outstanding,” said Kumarasingam. “With the PT6A engine, we’re delivering innovative hardware and responsive care – . In fact, we’re seeing interest from aircraft OEMs to incorporate ESPecially for Your PT6 engine plan into their own maintenance packages to offer the most comprehensive ‘tip-to-tail’ aircraft coverage.”
New Engine ESP Plan Option: Apply your ESP investment toward a new engine or new engine conversion at Time of Overhaul
For customers already enrolled in an ESP plan and contributing on a per-flying-hour basis, P&WC has enhanced the plan to allow customers to select a new engine of the same model or a new engine conversion upgrade at time of overhaul for an additional cost.
“Exceptionally simple and flexible, this ESP plan enhancement is applicable on all active P&WC engine programs and gives our customers the ability to choose how their investment in ESP pay-per-hour plan coverage is applied at the time of overhaul,” continued Kumarasingam. “In addition to a higher residual value and/or a performance upgrade, customers will have all of the advantages that come with a new engine – from first run warranty and a parts service policy in full, to improved aircraft resale value.”

The PT6 engine from Pratt & Whitney was innovative, and has been a mainstay in small aircraft production for 50 years. The engine could not have happened without the dedicated and talented team of 12 engineers, now known as the “PT6 Pioneers,” who created and developed the engine into the powerhouse that it is today. One of those pioneers, Gordon Hardy, recently spoke to PT6 Nation about the historic creation of Pratt & Whitney’s first turbine engine.
A tour of Mr. Hardy’s home reveals displayed sketches of the PT6 when it was simply an idea on paper, and the faded ink demonstrates a time when technology used to design engines did not exist. Today, engine parts are designed digitally from the casting process through to the final inspection. The sketches Mr. Hardy has on display show how far the PT6 has come over the years. Mr. Hardy credits his wife with being a huge support for him through the process as the early days required him to work long hours, keeping him away from the family for extended periods. Mr. Hardy and his wife, Margaret, came to Quebec, Canada from England in 1957 to work as a designer at United Technologies. He joined the P6 Pioneers in 1963.
Mr. Hardy says that in the early development of the PT6, the engineers discovered here was a gap in the power range between 400 and 2,000 where there were not too many turbine engines available. The engineers looked at the Beaver aircraft and determined that type aircraft that could benefit from a good turbine engine. He says that it turned out to be the perfect type of engine for that aircraft.
The center mounts on the engine enable fast removal of the power section, which enables inspections to be performed more easily. The unique design of the engine allows maintenance to be performed both on and off the aircraft, making maintenance and repairs much easier. When the PT6 was developed, there was a fixed shaft engine available, but it had features that were not as appealing, according to Mr. Hardy. Handling with fixed shaft engines was compromised as was the speed range, and the PT6 Pioneers realized that with a free shaft turbine, sections of the engine could be separated to provide better handling and speed. This provided excellent flexibility over other engines. The reverse-flow of the engine also allowed for a much quieter engine and was less susceptible to damage from birds or other debris.
Gordon Hardy, one of the PT6 Pioneers, made history when he assisted in the development of the historic Pratt & Whitney PT6 engine. In the final part of this four part series, Covington Aircraft talks about the innovation in an engine that was ahead of its time.

A discussion with an expert in airplane overhaul and maintenance and aviation engine service
David Hamilton knows a thing or two about aircraft repair. As a teenager, he began working for Covington Aircraft part-time, helping them with their aircraft engine overhaul and aviation engine service business. Now, over 25 years later, David is the Vice President and Operations Manager of the Covington Aircraft Engines Turbine Division. But he isn’t focused on the past; he’s focused on the future of airplane maintenance, repair and overhaul. Here’s an interview with David himself:
Walk us through a typical day. What does your job entail now, and how has it changed from when you started?
David: “I started working part-time on overhauled aircraft engines when I was 15. Covington is the only place I have ever worked. Now, my job consists of organization of personnel, materials, facilities and parts to supply the needs and requirements of our customers’ work orders. I coordinate jobs through our facility for those same customers. I arrange purchases and sales of engines for our facility, coordinating exchanges, overhauls and repairs to meet any changing needs our customers may have.”
Where do you see Covington Aircraft going in the next 5 years?
David: “I see us growing in the PT6A market, as our relationships expand in the corporate and military markets. I also believe we will continue to be a leader within the AG market, supporting our faithful customer base. As the AG market moves more toward larger engines, I believe we will become the premier overhaul and maintenance shop to meet their needs. We owe the AG market a lot, not just in our customer’s faithfulness but for the lessons that will serve us well as we go after new business outside that market. We have a strong desire to grow, but not at the cost of our current customer base.
Being very customer-oriented, I believe the lessons we have learned in the AG market, concerning AOG situations and personal attention to individuals, are exactly what the Corporate and Military Markets are looking for. We intend to meet and exceed those expectations.”
