7. Contingencies and accidents: repair, arbitration, and management of ‘potential hours’
A case of a serious incident (collision, structural damage) is used to describe the mechanics: securing, technical report, dialogue between DMAé–DGA–industry, costing and repair plan (technical expertise), technical and financial proposal, negotiation, launch of work, then return to airworthiness (authorities involved cited: technical authority, DGA, employment authority, DSAé).
Two key ideas:
- major repairs take time (design office, workshop), but the process is structured;
- the impact on flight hours is handled through fleet management: the fleet is a reservoir of hours. Based on a target of 250 hours/year on average, certain aircraft can be ‘pushed’ more at times (over 1–3 years) and then compensated for by reducing their activity, shifting the load to other aircraft (a logic already seen in targeted retrofits, particularly in the Navy).
The director paints a picture: not every aircraft flies exactly 250 hours per year, but over ten years, the average is maintained through potential management discipline, as the fleet must be kept going until a successor arrives.
8. Interface tools: support management centres (PCS)
PCSs are presented as a practical local interface that enables direct dialogue between the armed forces, industry and the DMAé, particularly when unexpected events occur: accidents, serious technical incidents (severity 1), airworthiness issues, quarantine decisions, risk assessments.
The PCS also serves as a mechanism for transparency on industrial constraints (e.g. supply chain tension) and operational needs (e.g. increased activity), so that everyone can anticipate and propose solutions.
9. ‘Cocooned aircraft’: past logic, different present context
The text indicates that in the mid-2010s, it may have been appropriate to put certain Rafale aircraft ‘in storage’ (potential regeneration), partly because not all aircraft were at the same level of equipment (e.g. AESA) and because the fleet structure (Mirage 2000 still numerous) offered margins.
Today, the diagnosis is clear:
- the minimum standard is high (F3R widespread; old F2/F3.2 aircraft gone ‘from the top’);
- the question is no longer ‘should we use this Rafale?’ but ‘we don't have enough’;
- there is no ‘stock’ of Rafales: no dormant fleet;
- the fleet is at full capacity: ‘every percentage point of availability is a battle’, and the margins are very small; losing a significant number of aircraft in combat would immediately become an issue.
The heterogeneous fleet (sensors and definitions) is recognised as both an asset and a liability.
10. The conceptual key: condition-based maintenance (testability + localisation + accessibility)
This is the doctrinal core of maintenance.
10.1 Principle
Condition-based maintenance aims to base maintenance on the actual condition observed, via sensors and integrated testability, rather than on a scheduled plan of periodic visits.
10.2 Requirements
The system imposes stringent requirements:
sensors and measurements everywhere (from the design stage);
software to operate these measurements (drift detection, predictive, fault detection);
above all: very high fault localisation rate, to avoid removing several pieces of equipment ‘for safety reasons’.
10.3 Operational execution
Consequences:
- fault reporting via maintenance pages;
- information available to the crew;
- data collation on return from mission;
- rapid standard exchange before the next flight.
A striking example is given: an engine can be changed in less than an hour, allowing for a very quick return to flight, whereas older aircraft require more time and space (e.g. Mirage 2000: half a day, larger team, more space).
10.4 Physical accessibility
Condition-based maintenance is reinforced by a highly advanced accessibility design: ‘hatches everywhere’, logical routing, avoiding the need to remove one piece of equipment to reach another. The absence of hatches on some ‘smooth’ aircraft is presented as a negative factor for maintainability.
10.5 Compromise with stealth
The compromise is accepted: opening hatches complicates electromagnetic stealth; therefore, the desired stealth must remain compatible with maintainability. The Rafale is positioned for ‘reasonable’ stealth (better than the Mirage 2000) so as not to sacrifice access.
10.6 Lesson in methodology
The thesis is explicit: this level of ambition cannot be ‘added’ after the fact. It must be specified from the outset, for all equipment, in a comprehensive manner, because any airworthiness failure counts for the crew.
11. MCO cost: delicate comparisons, but clear life cycle logic
The argument rejects a raw comparison between the Mirage 2000 and the Rafale at a late stage, as the cost depends on the stage of the life cycle: fewer aircraft, obsolescence, fixed costs spread over a smaller base, etc. The Mirage 2000 should be compared ‘at the heart of its life’ with the Rafale ‘at the heart of its life’.
However, two ideas remain:
- modern aircraft are more densely equipped and integrated (analogy with Motorola vs iPhone);
- competitiveness can be seen in the export market: price and maintainability are attractive enough that Mirage nations have switched to Rafale.
On heavy inspections, the text specifies: Rafale does not exclude ‘stripping’ operations, but these are often carried out opportunistically during capacity upgrades and ageing checks (corrosion, cracks, etc.), rather than in the form of major periodic inspections that immobilise the aircraft.
12. Logistical footprint and projection: maintenance load as a strategic variable
The maintenance load is presented as an initial, contractual requirement, followed standard after standard, including F5: do not increase the load, as this means more mechanics (a scarce resource) and reduced exportability.
Projection benefits from the ‘as-needed’ approach: there is less need to bring along a logistics train corresponding to a scheduled maintenance plan; a backup batch is carried, and the footprint is reduced. Comparative example provided: Mirage 2000 deployment with 16 trucks (cited experience), versus Pégase-type Rafale projection models (three Rafale + MRTT + A400M).
The text also mentions the prospect of sharing parts with partners (subject to agreements and airworthiness constraints) and the arrival of optimisation/predictive tools to reduce tasks and adapt maintenance to constrained environments (Africa vs mainland France).
13. High intensity: five DMAé axes (preparation, expertise, supply chain, innovation, organisation)
The ‘high intensity’ sequence is structured around five axes:
- Preparation: increasing exercises, crisis maintenance, aircraft tours, dispersion, remote projection.
- Technical expertise: re-acculturation to combat damage; rapid repair as close as possible; switch to degraded operation; use of degraded modes provided for in the design (redundancies, acceptable partial losses).
- Key concept: ORM (operational risk management); accepting different levels of risk depending on the context (illustrated by the transition from 10-6 to 10-4).
- Supply chain: balance between stocks and flows; impossibility of storing everything everywhere; need for a rear base and ramp-up of spare parts.
- Innovation: use of maintenance and ageing data, optimisation of fleet management (choosing ‘the 30 best’ out of 100 for projection), logistical anticipation; diagnostic tools, NDT, additive manufacturing, decision support, demonstrators.
DMAé organisation: ability to contract more quickly, adapt contracts and processes without losing rigour, typical objective: to achieve in one month what would normally take nine months.
All of this is put into perspective: these approaches must be identified upstream in strategies to support future systems (Rafale F5, drone, SCAF).
14. Conclusion: the Rafale as a sustainable programme and general lesson
The director concludes by presenting the Rafale as a major post-war programme, not only because of its design and export success, but also because of user satisfaction with an aircraft that is efficient, versatile and easy to maintain in operational terms.
The lesson learned is a rule of method:
when essential support requirements are integrated upstream, the programme runs more smoothly because the user is satisfied and long-term development remains possible on a basis accepted by the armed forces.
