Jet Parts Engineering, Inc.

Jet Parts Engineering, Inc. is a US-based firm specializing in the design and manufacture of aviation parts and repair services, offering cost-effective alternatives to original equipment manufacturer products. Founded in 1994 and headquartered in Seattle, US, Jet Parts Engineering focuses on providing engineering solutions for the aviation sector. The company has remained consistent in its business strategy, with a singular deal recorded in 2018 when Vance Street Capital recapitalized the firm, alongside investments from Lexington Partners, MLC Private Equity, Neuberger Berman, and Private Advisors.

The company operates independently without known subsidiaries. Jet Parts Engineering specializes in the design and manufacturing of PMA (Parts Manufacturer Approval) parts, DER (Designated Engineering Representative) repairs, and comprehensive MRO (Maintenance, Repair, and Overhaul) services tailored for the aviation industry. Their core offerings include custom-engineered solutions for airframe, component, and engine parts, which address the need for cost-effective and high-quality alternatives to original equipment manufacturer products. The company emphasizes quality and efficiency to maintain aircraft safety and performance while minimizing downtime for operators.

They serve a diverse client base, including airlines, maintenance organizations, and aviation service providers across North America and Europe. Jet Parts Engineering generates revenue primarily through B2B transactions, supplying aviation parts and repair services directly to commercial airlines and maintenance facilities. The transaction structure typically involves negotiated contracts that secure ongoing partnerships with clients, facilitating bulk orders of PMA parts and customized repair services. Clients may engage in multi-year agreements that outline terms for pricing and delivery schedules, aiming to streamline their supply chain while reducing operational costs.

The company’s hallmark products, including a range of PMA parts and specific DER repairs, are offered at competitive pricing designed to attract long-term contracts, fostering strong customer loyalty and repeat business within the aviation sector. Jet Parts Engineering plans to utilize the growth capital raised in July 2018 to further develop their product line and expand into new markets. They aim to launch new PMA parts and repair services tailored to emerging aviation technologies by the end of 2023. Additionally, the company is targeting expansion into Asian markets, particularly focusing on opportunities in China and India, with plans to establish partnerships by 2024.

The recent funding will support these initiatives and enhance their capacity to meet the evolving needs of the aviation industry. In January 2026, TransDigm Group, Inc. agreed to acquire Jet Parts Engineering, Inc. from PA Capital, Vance St.

Capital, Neuberger Berman, and MLC Private Equity for USD 2. 2 billion.
