Spirit AeroSystems, Inc. celebrated the rollout of the first flight test pylon for the Mitsubishi Regional Jet (MRJ) aircraft. The pylon and underwing structure are used to mount the aircraft's Pratt & Whitney power plant to the wing and are designed and manufactured by Spirit at the company's Wichita, Kan., facility.

"This rollout marks a pivotal milestone and highlights a unique opportunity to collaborate with a new original equipment manufacturer in developing an all-new aircraft for the 70 to 100-seat market segment," said Cathy McClain, director of Business and Regional Jet programs for Spirit.

"Spirit has extensive experience with underwing pylons, and is honored to work with Mitsubishi Aircraft Corporation on this program," said David Coleal, executive vice president, Boeing, Business/Regional Jets, and Aftermarket. "The MRJ aircraft pylon is the latest example of how we put our team's creativity, determination and expertise to work in support of our customer."

In 2008, Mitsubishi awarded a contract to Spirit AeroSystems to design and build pylons for both the MRJ70 and MRJ90 aircraft models. The work package also includes systems, pylon-to-wing integration hardware and the aft fairing package. Spirit has more than 75 years of experience designing and producing pylons.

An industry team of Spirit, Mitsubishi and Pratt & Whitney have worked together to define structural interface points and complete the pylon structural design. The finished product is made of lightweight aluminum, titanium and composite components, and is a combination of purchased items, Spirit-fabricated components and Mitsubishi-furnished equipment.

"Working together, Spirit and Mitsubishi have forged a strong, productive relationship based on mutual respect and quality," said Marshall Philips, program manager of Spirit's MRJ aircraft pylon program. "Going forward, this robust relationship has both companies poised for the success and growth of the MRJ program."

The MRJ is a next-generation regional jet developed by Mitsubishi Aircraft based on technology cultivated by Mitsubishi Heavy Industries. The MRJ family consists of the MRJ90 (90 seat class) and the MRJ70 (70 seat class). These aircraft have common wings, empennage, engines and systems. In addition, they have commonalities in pilot type rating, maintenance program and spare parts.
