Cambridge-based aerospace company Marshall and Romanian aerospace maintenance and manufacturing specialist Romaero announced on Friday a collaboration that provides a broad framework for programmed depot maintenance (PDM) of current and future C-130 Hercules aircraft operated by the Romanian Air Force (RoAF), the Romaero said in a release."As Romania seeks to expand its sovereign airlift capability, the Ministry of National Defence has embarked on an ambitious modernisation programme for RoAF's fleet of legacy C-130 aircraft, including the replacement of existing airframes. These plans will substantially increase the scope and scale of in-service support work to be undertaken towards the upkeep of the aircraft," the release said.The new agreement establishes a comprehensive framework for Marshall and Romaero to deliver all anticipated aspects of sustainment for RoAF's C-130 fleet. Working together, the two companies will develop and present plans for programmed depot maintenance, including supply chain management for equipment and materials.Marshall will also provide engineering support on repairs, airworthiness assessment and technical publications, enhancing Romaero's in-country work to keep the RoAF aircraft mission-ready and mission-capable."Following a thorough selection process, we are pleased to be collaborating with Marshall for the sustainment of the RoAF C-130 fleet. The Marshall team stands out for its depth of experience, full transparency, breadth of technical knowledge and impressive heritage of working on the C-130 platform," said Romaero CEO Bogdan Costas, as cited in the release.The framework of the collaboration has been defined in an initial memorandum of understanding (MoU) between the two companies, signed at Marshall's headquarters in Cambridge, UK. Maintenance work on the first aircraft is anticipated to commence in 2026."We are excited to work alongside the Romaero team and contribute to their delivery of high-quality and timely service to RoAF. For Marshall, this collaboration isn't just a chance to work with a new C-130 operator; it's about building a long-term relationship around a vital national defence programme undertaken by a key NATO member," said Marshall Aeronautical Engineering Services Director Mark Hewer.Romaero will conduct in-country maintenance and engineering work on the aircraft from its hangarage located adjacent to Bucharest Baneasa airport.
