Boeing and Ontic Expand Global Distribution of Grimes Engine Valves
Boeing and Ontic expand their partnership to supply over 1,000 Grimes engine valve parts globally, improving lead times and AOG support.
Boeing and Ontic Expand Partnership to Streamline Global Engine Valve Distribution
Boeing and Ontic have announced an expanded distribution agreement at the MRO Americas 2026 conference in Orlando, Florida. The partnership aims to supply critical Grimes engine valves to commercial airlines globally, addressing ongoing supply chain demands in the aviation aftermarket.
According to the official press release, this collaboration leverages Boeing Distribution’s extensive global logistics network alongside Ontic’s specialized manufacturing expertise. Ontic serves as the Original Equipment Manufacturer (OEM) and license holder for these legacy components, ensuring that operators have reliable access to high-quality valves essential for safe flight operations.
The agreement is designed to shorten lead times and improve aircraft readiness. By adding more than 1,000 new parts to Boeing’s e-commerce catalog, the partnership ensures operators and Maintenance, Repair, and Overhaul (MRO) facilities have robust 24/7/365 Aircraft on Ground (AOG) support.
Expanding the Global Supply Chain
The aviation aftermarket is currently navigating persistent supply chain constraints, particularly regarding hard-to-source components for mature aircraft platforms. To address this, the expanded agreement introduces new global inventory positions and distribution points aimed at strengthening AOG response capabilities.
By integrating Ontic’s manufacturing capabilities with Boeing’s established relationships with commercial airlines, the partnership provides technical assistance and streamlined procurement processes. This strategy is intended to reduce costly aircraft downtime and lower overall operational expenses for airlines worldwide.
The Legacy of Grimes Engine Valves
The components at the center of this agreement are Grimes engine valves. Industry data indicates that the Grimes brand, which originated in 1933, encompasses critical fluid pumping, fuel control, air shutoff, and solenoid valves. These parts are vital for engine fuel management and pneumatic systems. Ontic currently holds the OEM licenses to manufacture and support these legacy parts, ensuring their continued availability for modern fleets.
Strategic Industry Consolidation
This announcement aligns with a broader industry trend of strategic consolidation between major aerospace distributors and specialized manufacturers. Boeing has been steadily expanding its exclusive distributor partnerships to ensure reliable, cost-effective solutions for airlines. Industry reports note that this builds upon a 10-year agreement signed between Boeing and Ontic in 2024 for actuation and propulsion system products.
Furthermore, market research from April 2026 highlights that Boeing has recently signed similar distribution agreements with other specialized manufacturers, including Honeywell, CTT Systems, and Survival Products, reinforcing its strategy to centralize aftermarket procurement.
Proactive Inventory Management
To combat ongoing component shortages, Ontic has also launched a proactive aircraft teardown procurement program. Beginning in April 2026 with the disassembly of an ex-Thai Airways Boeing 747-400, this initiative aims to recover complex assemblies, including valves and actuators, to secure critical inventory before supply constraints severely impact operators.
Industry Perspectives
Executives from both companies emphasized the operational benefits of the expanded catalog and global reach.
“By leveraging our capabilities, expertise and global network, this expanding agreement with Ontic ensures these critical engine valves are readily available where operators need them most, faster and more reliably,” said William Ampofo, senior vice president, Parts & Distribution and Supply Chain, Boeing Global Services, in the company’s press release.
“This new agreement reflects our shared commitment to aviation safety and operational excellence, providing airlines with the confidence that comes from knowing essential components are supported by industry leading distribution and manufacturing capabilities,” stated Brian Sartain, chief operating officer, Ontic Engineering & Manufacturing.
AirPro News analysis
We view this expanded partnership as a direct and necessary response to the global supply chain bottlenecks currently challenging the aviation sector. By positioning inventory globally and utilizing modern e-commerce platforms, Boeing and Ontic are actively mitigating AOG situations, which remain a significant financial and operational pain point for commercial airlines. Furthermore, this move underscores the enduring importance of legacy brands like Grimes in maintaining the safety and operational viability of mature fleets. As major distributors continue to consolidate their networks, airlines stand to benefit from simplified procurement and reduced lead times.
