Raytheon Technologies: Pratt & Whitney Aftermarket Highlights Sustainability Practices and Technology Advancements at Commercial MRO Sites in North America

DALLAS, April 27, 2022 – Pratt & Whitney, approaching 100and year of designing, manufacturing and servicing aircraft engines, drives the development of innovative technologies and greener business practices at its US-based maintenance, repair and overhaul (MRO) facilities for the commercial aviation. Since the company’s inception, Pratt & Whitney experts have analyzed industry trends and continually modernized to provide world-class customer support that optimizes engine fleet performance and reliability, minimizes costs and advances preventive maintenance for operators worldwide.

“In a typical jet engine, 15,000 or more parts come together. Similarly, in the aviation industry, innovation in technology, products and processes must merge with sustainability initiatives to advance the industry,” said Joe Sylvestro, senior vice president of Aftermarket and Support Operations at Pratt & Whitney. “As the pace of change quickens, our passion for technological advancement deepens.”

Pratt & Whitney is focused on inserting technology into its shops to boost productivity and efficiency. For example, the company’s Dallas airfoil repair and operations facility recently demonstrated a new, patented system that streamlines parts inspection with a capability that has not yet been deployed in the workshop. Additionally, to support increased F135 parts repair work in its East Hartford repair operations division, Pratt & Whitney has also invested in a new laser drill, waterjet tape, three-dimensional measuring machine and air circulation equipment.

Technology insertion is also used at Pratt & Whitney’s three customer training centers located in East Hartford, Connecticut; Beijing, China; and Hyderabad, India. Typically training more than 6,000 students a year, the company’s maintenance training has evolved to incorporate new technologies into traditional hands-on, instructor-led training methods. A 3D application called EngineExplorer has been developed for the Pratt & Whitney GTF™ engine, V2500 and F135 engine models, which allows instructors to separate and rotate the engine, isolate engine systems, search for parts specific and annotate and highlight areas of an engine. Pratt & Whitney is also developing ways to incorporate virtual and augmented reality into training, helping to improve lessons by making them more immersive and engaging.

To more easily integrate flight operations and engine health information and customize scopes of work for MRO shop visits, many airlines are turning to data analytics to bolster their in-house engineering teams. and maintenance. EngineWise® Data by ADEM™ (Advanced Diagnostics and Engine Monitoring) enables Pratt & Whitney to manage customers’ engine health and maintenance scheduling requirements, working to maximize engine performance and time specific to each customer, while maintaining predictable MRO expenses. The system currently provides analyzes for more than 9,500 engines in service. The GTF engines alone generate around four million data points over an average two-hour flight. Expert data analysts use this data to help reduce operational disruptions through predictive and preventive maintenance.

“Our employees rise to the challenge every day, innovating to drive the industry forward,” said Sylvestro. “For us, it’s about getting people reliably to their destinations. It’s about providing the care and intelligence to expertly service aircraft engines. And, ultimately, it’s about designing a new and exciting sustainable future for aviation.”

As a leading manufacturer of propulsion systems for the aerospace industry, Pratt & Whitney has an important stake and role to play in protecting our planet. The company has implemented a sustainability strategy framework focused on smarter engines and technologies, cleaner fuels, and a commitment to operate cleaner, more sustainable facilities. Pratt & Whitney’s global MRO sites are rethinking their operations and adopting greener business practices to reduce their environmental impact, including:

  • The Pratt & Whitney Columbus Engine Center features a closed-loop clean line process for the GTF engine, enabling water reclamation and eliminating the need for more than one million gallons of fresh water per year. The savings are expected to increase as GTF throughput increases in future years. In addition, the company collects water from the roof and stores it in reservoirs to then use it for other purposes, including landscape irrigation.

  • In Arkansas, the company has made tremendous progress with its rainwater harvesting system, solar field and other sustainability projects. Since 2010, water consumption has improved by 32% and annual greenhouse gas emissions have decreased by 400 metric tons.

  • Dallas employees have developed an environmentally friendly laser to clean engine parts. The laser – unlike conventional abrasive blasting and powerful water blasting – vaporizes grit, dust and rust from components, reducing material consumption, emissions and industrial waste.

  • EcoPower is an engine wash service available through EcoServices, LLC, a joint venture of Pratt & Whitney. It is a closed-loop wash system, using only highly purified heated atomized water to effectively clean the motors. Using this sustainable process for a fleet of ten A320s over a period of five years, for example, would reuse over 90,000 liters of water and result in the elimination of 8,600 tonnes of CO2 and 3.3 million liters fuel savings.

Founded by Frederick Rentschler in Connecticut in 1925, Pratt & Whitney has been an innovation leader for passenger flights and military missions since its first Wasp engine. Today, the company manufactures the most advanced operational combat engine, the F135 engine, as well as the most durable commercial engine for single-aisle aircraft, the Pratt & Whitney GTF engine. With more than 10,000 engine orders and commitments from more than 80 customers, GTF engines now power more than 1,200 aircraft with 62 operators across three aircraft families. To keep pace with the growing fleet, the GTF MRO network continues to expand worldwide. Visit for more information.
