Aerospace OEM (Original Equipment Manager) Ontic has appointed aircraft technician Jonathan Grant as its new Chief Engineer, placing him at the head of the company’s engineering and technical operations, as the company attempts to balance its relationships with a range of stakeholders across the aviation sector.
Who is Jonathan Grant?
Jonathan Grant has been working in the aviation sector since September 2006, when he was hired by Boeing as a systems engineer.
Grant had worked with the aircraft manufacturer Boeing for over 15 years, before becoming Head of Engineering at the aerospace engineering and flight-test company AeroTEC.
His time at the manufacturer included leading the system integrations programme for the Boeing 737 MAX, which entered commercial use in May 2017.
Grant worked as Director of Safety and Regulatory Affairs at Boeing from November 2019 until he left the company in January 2022.
His most recent position in the aviation industry was as Head of Engineering at the aerospace engineering and flight-test company AeroTEC, where he worked from March 2025 until September this year.
Ontic’s Chief Operating Officer, Brian Sartain, said that,
“Jonathan’s depth of experience in aerospace engineering, safety and certification makes him the right person to lead our technical authority globally.”
Grant’s new role will reportedly allow him to continue working in Seattle, WA, where he has been based since leaving Boeing.
What Does Ontic Do?
Ontic is one of the aviation industry’s largest Original Equipment Manufacturers (OEMs).
OEMs work to design, certify and build aircraft components which are then sold and transported to manufacturers.
Ontic also works to supply spare parts both to commercial aircraft manufacturers Boeing and Airbus, and to military aircraft manufacturers including Lockheed Martin and Bombardier.
Grant has said that,
“The products OEMs built five, ten, and twenty years ago remain the backbone of global aviation, and keeping them working is one of the most interesting problems to solve anywhere.”
Ontic operates from ten sits across the world, including five in the U.S., four in the UK, and one in Singapore.
