Maintenance, Repair and Overhaul

Maintenance Repair Overhaul

Aircraft availability depends heavily on the efficiency and effectiveness of Maintenance Repair and Overhaul (MRO) activities. However, military operators are increasingly under pressure to reduce their MRO costs, without compromising fleet effectiveness or safety, while dealing with changing operational requirements and supply-chain and resource issues.

Marshall Aerospace and Defence Group offers world-leading MRO services to the operators of fixed-wing military aircraft, with particular experience on transport derivatives. We have been maintaining the C-130 Hercules transport aircraft of the United Kingdom’s Royal Air Force and selected European air forces for about 50 years; efforts which have contributed towards the C-130 Hercules becoming one of the RAF’s most cost-effective transport aircraft.

A continuous improvement programme ensures we keep pace with advancing industry methods and techniques. We invest heavily in training and have 1,750 highly skilled personnel, based at our 800-acre Cambridge site which has 1.25million square feet of hangar space and a runway capable of accepting aircraft up to Boeing 747 size.

Whether for routine maintenance or in response to an Aircraft On Ground (AOG) situation, our dedicated maintenance technicians and support areas specialise in translating contracted work into inspections, rectification and fault-finding activities, with the sole aim of returning the aircraft to operation in a safe and airworthy condition within the agreed downtime.

Our MRO capabilities include but are not limited to:

  • Aircraft strip and repaint
  • Inspections to OEM standards
  • Preventative and corrective maintenance
  • Repair assessment, rectification and recovery (metallic and composite)
  • Modifications and upgrades associated with systems and structural components
  • Parts procurement, manufacture / fabrication (subject to requisite approvals) and Supply Chain Management
  • Comprehensive back shop support and industry network for components
  • Non Destructive Testing (NDT) and development of inspection techniques

Specifically for the C-130 Hercules, we have developed an enviable knowledge and ability associated with the replacement and repair of complex structural components, including:

  • Centre wing and outer wing ‘rainbow’ fittings (including corner fittings)
  • Sloping longerons
  • Undercarriage beams
  • Wing rear spar
  • Composite panel / fairings

However, the skills and procedures developed and refined for working on the above complex structures can easily be applied to any platform.

We are renowned for our strong project management and our resultant ability to combine maintenance activities with significant aircraft modification programmes, including full glass flight deck upgrades, as well as testing and certification. Mission fits and Urgent Operational Requirements (UORs) are also a Marshall speciality. These can be on a stand-alone basis or, again, in conjunction with a maintenance input.

Our project/programme management skills and flexible approach to work patterns are employed to ensure that aircraft are returned on time, including emergent work encountered during the programme, and to the high standards demanded by our customers, the industry and its regulators.

We are expert at developing low-risk, cost-effective MRO solutions to meet our customers’ needs. Our engineering capabilities and reputation for integrity have enabled us to establish trusted relationships with the leading manufacturers of airframes, engines and components.

The focus of our industry-leading MRO services is to deliver a ‘fit-for-purpose’ product to quality, cost and time commitments, ensuring we maintain the very highest levels of customer satisfaction.
