Responsibility for the information and views expressed in the study lies entirely with the authors CEIS | 2015 | MRO of military helicopter engines 3 | 40 CEIS is a strategic consulting firm Our mission is to assist our clients in defining their strategies and developing their activities in France and abroad. In order to achieve this goal, we combine foresight approach and operational business support with actionable information to support decision- making and action. CEIS’ Defence and Security activity gathers sector-specific expertise and involves more than twenty consultants and analysts who have access to an international network of hundreds of experts and organisations. Based in Brussels, CEIS - European Office advises and assists European and national, public and private actors in the development of their European strategies, in particular in the fields of defence & security, transport, energy and maritime affairs. CEIS - European Office also takes part in European research projects in these areas. To carry out all of its missions, the team relies on an extensive European network of contacts, experts and partners. The SIA Lab has been implemented and is led By CEIS, which acts under the responsibility of Sopra Group, the architect and integrator of the SIA programme (Army Information System). This innovative concept of the Directorate General of Armaments aims to identify, test, and demonstrate off-the-shelf technological bricks CEIS | 2015 | MRO of military helicopter engines 4 | 40 stemming from innovative SMEs and industrial players. The SIA Lab brings together users and developers of the SIA programme and potential solution providers. It is also a space for brainstorming and discussion aimed at better understanding user needs and requirements as well as ensuring the suitability of the presented solutions.

MRO can be defined as “the sum of tasks required to ensure the functioning and availability of equipment. […] MRO brings together the functions of maintenance, repairs, logistics (supply, storage and distribution of replacement parts) or, in other words aircraft or aircraft component support.” The relavance and ubiquity of helicopters in all modern operations is such that it seemed important to address the constraints, challenges and possible solutions to the issue of their maintenance, all the while analysing the indispensable link between MRO performance and the operational capability of the Armed Forces. This latest Strategic Note addresses the specific issue of propulsion, which constitutes one of the most important subsets, and one of the major cost centres of helicopters. An overall analysis of the aerospace MRO of helicopters will be the subject of an upcoming Strategic Note (fall 2015). 1 http://www.ceis.eu/fr/etudes-et-solutions-strategiques/actu/strategic-study- aerospace-mro-key-issue-capability-based CEIS | 2015 | MRO of military helicopter engines 7 | 40 Executive Summary At a time when budgetary constraints are increasingly pressing for the Armed Forces, exchanges between the forces and industry provide opportunities to improve optimization of costs. The British Ministry of Defence (MoD) has studied the transition from six separate support contracts for the same type of engine to one overall support contract and calculated that the direct and indirect gains amount to some £300m over twenty years. Their experience demonstrates that such contracts optimise the engines’ ‘time-on-wing’ (avoiding too many removals), improve their reliability, lengthen the lifespan of Life Limited Parts (LLP) and allow greater recourse to repairs as opposed to ordering replacement parts. The establishment of such contracting solutions gives the armed forces greater visibility as to the use of their machines, with the necessary built-in flexibility in case of peak activity during operations or, alternatively, reduced activity. Maintenance is also subject to budgets constraints which, in turn, ultimately affect the operational capabilities of armed forces. Solutions for overall support can mitigate these budgetary risks and allow for optimal availability. On the basis of ongoing exchanges on needs and expectations during preliminary discussions and subsequently during implementation, the ‘virtuous’ side of this type of contract lies in this ability to provide visibility to all stakeholders while CEIS | 2015 | MRO of military helicopter engines 8 | 40 manufacturers will make gains in production planning. This type of solution therefore has real advantages over traditional ‘Time & Material’ contracts, under which there is typically an increase in the maintenance costs (Direct Maintenance Cost) and a decrease in the operational availability of an aircraft during its operational lifespan. A good example of these advantages is the support response provided by manufacturers to the problems faced by the French Caracal turboshafts in Mali, which demonstrated the flexibility of such ‘overall support’ contracts and enabled operators to focus on achieving their mission. CEIS | 2015 | MRO of military helicopter engines 9 | 40 Introduction In January 2007, during the seizure of Fort Jugroom in Helmand province, Afghanistan, 45 Commando Royal Marines led a rescue of one of their men surrounded by Taliban forces. The originality of the mission lay in the use of WAH-64 Apache attack helicopters which, aside from the fire-support provided to ground elements, allowed a recovery group of four men seated on the Apache’s avionics bays to deploy at close-quarters to the Royal Marine in difficulty. This improvised rescue2 highlighted the helicopter's adaptability in current theaters of operation. The helicopter is therefore a force multiplier: it allows decision-makers on the ground to shed light on the tactical situation and gives them a rapid reaction force which can be flexible in its uses. The essential nature of the helicopter’s contribution to current military operations is based on its flight characteristics (vertical take- off and landing, manoeuvrability), which are based on complex mechanical and dynamic systems. The sum total of the operational parameters which illustrate the complexity of a helicopter’s workings demonstrates the meticulous maintenance which they require. The purpose of 2 It is interesting to note that, in this specific case, an attack helicopter was used as a transport helicopter in a rescue operation during combat. CEIS | 2015 | MRO of military helicopter engines 10 | 40 this note is to use specific examples to illustrate the evolution of MRO and the solutions put forward so that the Armed Forces may fulfil their operational contract, or as General Girier, central director of the SIMMAD3, said: "Let them fly." Three examples from France, the United Kingdom and Brazil, based on the same type of service, demonstrate that overall support contracts can adapt to the different needs of each client and provide solutions to a single end: the accomplishment of the mission. 3 ‘Structure Intégrée de Maintien en condition opérationnelle des Matériels Aéronautiques de la Défense.’ ‘Integrated Structure for the Maintenance, Repair and Overhaul of Aerospace Equipment’ of the French Ministry of Defence. CEIS | 2015 | MRO of military helicopter engines 11 | 40 Helicopter MRO Types of military helicopters The categorisation of military helicopters is not only based on the types of missions assigned to them. Modern aircraft are designed to fulfil a primary mission and also a number of secondary missions. It is therefore possible, by installing ‘kits’ or specific pieces of equipment (e.g. a winch, a cargo hook, an in-flight refuelling probe), to quickly adapt an aircraft to a new mission. It therefore seems more relevant to categorise according to the size and the number of engines on the aircraft: - Light helicopters: within this category we can distinguish between Single Engine and Light Twin; their MTOW4 varies from one to four tons. Examples: Gazelles (SA341/342), H145M (ex-EC645 T2); OH-58 Kiowa
