Philip Stevens reports for Aviation News from the largest storage facility in Europe.
Châteaudun air base (Base Aérienne 279) the home of Entrepôt de l'Armée de l'air 601 (EAA 601 - French Air Force Warehouse). Formed in 1951 EAA 601 is the largest aircraft storage centre in Europe. It is essentially a Gallic version of AMARG (Aerospace Maintenance and Regeneration Group), but unlike Davis Monthan AFB in the dry Arizona desert heat, the Armée de l'air (AdA) has to store its reserve fleet of aircraft inside climate controlled hangars awaiting a time when they are either returned to service or otherwise disposed of from the inventory.
Commandant (Cdt) Sylvain Lavignac, is the current Commander of 11.601 Aircraft Maintenance, Repair and Storage Group (Groupe d'entretien de réparation et de stockage des aéronefs - 11.601 GERSA), the principle host unit at Châteaudun. GERSA is responsible for the receipt, storage and dispatch of currently 440 aircraft, 194 of which are stored in humidity controlled hangars. Roughly half are unliekly to fly again. Among the types held on site are; Dassault Mirage F.1, Dassault Mirage 2000, Dassault/Dornier Alpha Jet, Socata TB 30 Epsilon and Embraer EMB-312 Tucano.
|Left out in the cold: The French authorities have yet to make a decision on what to do with their long time retired Mirage IVAs and IVPs in open storage at Châteaudun some since the early 1990s. These former supersonic strategic bombers from the Cold War era first entered service in 1964 and were originally designed to carry the French nuclear deterrent. 21 aircraft were later modified to carry the ASMP medium-range nuclear missile, designated Mirage IVP (penetration) these entered service in 1986, the remaining IVAs were retired at this time. In 1996 its nuclear role was transferred to the Mirage 2000N. The twelve remaining Mirage IVP were modified for the reconnaissance role and served extensively in the 1999 Kosovo operation, five aircraft continued in service until 2005. Of the 62 Mirage IVs built 15 IVAs and IVPs are stored outside around the Poulmic storage hangar.

|Facing new challenges
Crucially, Cdt Lavignac also revealed that GERSA faces increased challenges over the next few years following the French Government's decision to rationalise the size of its fleet of military aircraft and the number of air bases it needs, this review was named 'Air 2010'. Cdt Lavignac has been told that he will have over 500 aircraft in his charge by 2015, as 'Air 2010' proposed that only 300 combat aircraft will be in service with the AdA by 2015.
Already numbers have started to increase as air bases are closed and units disband. Recent arrivals here have included at least 16 of the older Mirage 2000Ns from the former EC 01.004 unit which disbanded at Luxeuil (BA 116) in July 2011. The aircrew transferred to EC 02.004 when they moved to Istres (BA 125). Other recent arrivals are the Mirage F.1CRs from Reims (BA 112) which was closed in September 2011, some of its aircraft were transferred to Mont-de-Marsan (BA 118) the remainder were put in to storage. 27 former BA 112 Mirage F.1B/CR/CT were noted in the GERSA hangars.
As Châteaudun has limited covered space of 98,425 Sq feet (30,000 Sq m) intense planning has been necessary to make sure they can accommodate the increasing numbers. GERSA work very closely with a unit at Bordeaux-Merignac (BA 106) known as Air Force Support Command (Commandement du Soutien des Forces Aériennes - CSFA). Established in 2008 CSFA has a staff of 21,500 and controls 300 military units. CSFA is divided into cells each responsible for an aircraft type, part of their responsibility is to manage the aircraft fleet's hours by rotating stored aircraft with those with the operational squadrons. They decide on which aircraft is put into storage and which is taken out, either to be returned to service or harvested for spare parts and ultimately scrapped. A plan is issued by CSFA every November which covers the movement of aircraft in and out of Châteaudun by aircraft type and for each month in the following year. Issued last November, the plan for 2012 shows that 40 aircraft will be added to the numbers in storage while only 20 will be taken out of storage.
Storing a sophisticated combat aircraft is no easy task, especially in a European climate. All the hangars available to GERSA are insulated with an inner lining of toughened plastic sheeting erected two meters or so from the outer wall. The sheeting is also suspended as a false ceiling above the aircraft.
North side of the single 7,552 foot (2,302m) runway are three more pairs of hangars. One hangar contains aircraft which have been involved in accidents which have been transported here for investigation by an external authority. Another hangar contained aircraft that had recently arrived and were waiting the attention of the GERSA technicians along with a number of retired aircraft which are being used as a source of spares.
As covered space is at a premium we currently have 246 aircraft stored outside at various points around the airfield. These have in the main been harvested for spare parts. One of the main storage areas is the southern end of the disused cross runway known as the "German runway." At its southern end there are over 50 forlorn looking airframes in various stages of dismantlement including; Mirage 2000C/N, Mirage F.1, Alpha Jet, Sepecat Jaguar, Fouga CM-170 Magister and the fuselages of 13 former French Navy (Aeronavale) Nord 262E transports the last of which flew in 2009. Outside at the nearby Nivouville site are another 19 Nord 262D Frégate which had operated with the AdA up to 2004. With these sorry looking aircraft are some eleven wingless Transport Allianz C-160F Transall and half a dozen or more Dassault Mystère 20. Some of these aircraft will linger on for a decade or more; others won't be so fortunate and will go to the melting pot.

When an aircraft arrives for storage it is transferred in to the main GERSA hangar the following day. Accompanying the aircraft will be its detailed technical maintenance and service record. “We don’t become the ‘owner’ of the aircraft without these records. The technical documentation advises us what work or maintenance we need to do on the aircraft”, explained Cdt Lavignac. The large GERSA hangar is divided in to three cells; the first cell is where aircraft are stripped down. A ‘zone de demantelement’ is created and three teams of specialist technicians descend upon the aircraft. The avionics team work on the electrical equipment including the Radar, the weapon systems and the hydraulic systems experts have their own tasks to perform. Weapon’s systems and the ejector seat(s) are all removed. The engine is taken out to be returned to the aircraft’s operational air base where it will be used to keep the unit’s other aircraft flying. The aircraft’s fuel tanks and hydraulics are then filled to 90% capacity to ensure these systems do not leak during its time in storage.
The aircraft will be held in storage for at least one year and often for two years or even more in some cases. Aircraft manufacturers have stated that an aircraft can be in storage for a maximum of two years, after which time it has to be returned to full flying order. After flight testing at Châteaudun it can be returned to storage for up to another two years assuming it is not required by an operational unit. After four years a Mirage 2000 for example will require ‘major’ maintenance which is carried out at the Industrial Workshop of Aeronautics (Atelier Industriel de l'Aéronautique - AIA) at Clermont Ferrand before it can be returned to storage. Each aircraft type is different noted Cdt Lavignac; “The Mirage F.1 creates the biggest problem for us, it has a tendency to leak due to its age. In contrast the Alpha Jet is an easier aircraft to store as its simple technology is easy to maintain”.
Returning aircraft back in to service
It is not a simple process to return a stored aircraft to flying order; some aircraft will have had parts removed from them during their time in storage to keep other aircraft flying. The administrators will keep track of which parts have been taken from a particular aircraft. One month before an aircraft is to be removed from storage a list is produced of all missing parts which need to be recovered from other stored aircraft. “It’s like a game you take it from one to put it in another, you gather the missing parts from as few as aircraft as possible”, explained Cdt Lavignac. The process is also made more complicated when during the storage period there may have been modifications or updates which now need to be applied. “Every day we have a meeting which we call the ‘mess’ with the chief of the exploitation division to resolve technical and logistical problems with every aircraft we are working on”, explained Cdt Lavignac, adding; “There is no set time to prepare an aircraft for flight, it depends on the amount of missing parts and the number of modifications and updates”. Typically it will take between three and five weeks to return an aircraft to the air, the process involves a team of technicians from each specialty; mechanical using three technicians and avionics with two to three technicians. At the end of the operation one or two weapons experts will complete their tasks, the fitting of the ejector is the last job. GERSA are trained to work on ten types of aircraft (Mirage 2000D, N, C/-5 and B, Mirage F.1B, CT, CR, Alpha Jet, Epsilon and Tucano). A limiting factor as to the amount of aircraft that can be worked on at any one time is the availability of Crew Chiefs who each manage a team to bring an aircraft back into flying order, for example there are only three Mirage F.1 Crew Chiefs at GERSA. An engine run is all that is required for restored aircraft before they are handed to the ferry pilots, with the exception of the Alpha Jet which requires a test flight before ferrying.
Pickup and drop, the Châteaudun “Taxi service”
One week before completion the Escadron de Convoyage (EdC) 00.070 ‘Châteaudun’ will be informed that an aircraft will require ferrying to its squadron. Based at Châteaudun EdC 00.070 has six pilots who ferry all AdA aircraft from and to Châteaudun and between maintenance centres and air bases. It is the only squadron dedicated to ferry pilots and aircraft around France.
The three fighter pilots can fly the complete range of ten or so types stored at the air base. New EdC 00.070 pilots go to the test pilot school to do two or three flights to get an overview of the flight characteristics of each aircraft. Cne Chaintreuil explained; ”It is easy to stay current on all the types we fly as the missions are quite simple, our aim is just to fly an aircraft from one base to another. The flights are not complicated as it is basic navigation”. There is some latitude for these ferry flights, although they have to be as straight as possible to save fuel and to keep flying hours to a minimum, they can fly at low-level if weather permits and there is low risk of bird strike.
The experienced Cne Chaintreuil is clearly enjoying his time with EdC 00.070; “Pilots at the ‘Châteaudun’ squadron choose to come because of the different types of aircraft we can fly. This could be our last flying job in the air force”. Pilots will stay with EdC 00.070 for between three and five years some as long as twelve years. Cne Chaintreuil described a typical tasking; “I could take-off from Châteaudun at 08:30 and fly to Clermont Ferrand with our three fighter pilots, two for a flight to Nancy in a Mirage 2000D. I could then take the other pilot to Istres for him to pick up an aircraft bound for Clermont Ferrand. I would then fly north to Nancy to pick up our pilots and ferry them home to Châteaudun”.
To plan these ferry flights all the AdA squadrons are linked to a dedicated office at Châteaudun known as the aircraft movement regulation desk (Bureau de la régulation des mouvements d'aéronefs – BRMA). BRMA collate all the requests and inform EdC 00.070 of the aircraft that need to be moved. “We then plan the ferry flights for the next two days for the optimum route. We also have to be very flexible as an aircraft can have technical faults at the last minute”.
Protecting the nation’s heritage
A number of aircraft are scrapped here each year under contracts with private contractors which are administered by the CSFA. Civilian rules regarding identification of materials and how it can be disposed for environmental reasons apply. Guided by the AdA’s headquarters aircraft can be saved from the melting pot. Cdt Lavignac does recognise the need to preserve aircraft for the nation. “We liaise with civilian associations who want to take aircraft from here to their museums. Staff from approved museums will come here two or three times a year to take pieces off aircraft to help with their restorations”.
GERSA also enjoys a close relationship with the on base museum which is situated in a hangar on the northern side. The Conservatoire d'Aéronefs Non Opérationnels Préservés et Exposés (CANOPEE) museum was officially opened in 2006 and houses a collection of around 50 former Châteaudun inmates from previous decades. Unfortunately, the museum is not currently open to the public.
Pressed to name a favourite aircraft in his charge, Cdt Lavignac does keep a watchful on eye on the 15 or so stored Dassault Mirage IV’s which have evaded scrapping since the last Mirage IVPs were retired in 2005. “I have affection for the Mirage IV it was the first aircraft I worked on when I was a young Sergeant and Radar specialist. It is a really beautiful aircraft”. Examples of the former supersonic strategic bomber and reconnaissance platform are currently stored outside around the Poulmic hangar. Although a number of Mirage IVA/P are already preserved in France, hopefully a few more will find a new home. However, there are no immediate plans to move them on at this time. I am sure Cdt Lavignac given the chance would like to take one home for himself!

Mirage 2000C (79 ‘115-LE’) arrived at Châteaudun after its long journey by road 1,900 mile (3,060 km) from Lithuania, it had been involved in a mid-air collision with a Lithuanian Air Force Aero L-39ZA Albatross during a training exercise on August 30, 2011. The crew of the L-39ZA lost control of their aircraft and were forced to eject.
Deliveries of the Mystère 20 began in the mid 1960s while some were retired between 2005 and 2007 the Flight Test Centre (Centre d'Essais en Vol - CEV) Mystère 20s which have been modified for various trials over the years continued in service till 2009 when No.86 'CG' was flown to Châteaudun.

Mirage 2000D (612 '133-JK') from BA 133 Nancy-Ochey but deployed to Kandahar in Afghanistan has recently returned following a crash about 60 miles (100 kilometres) west of Farah on May 24, 2011. It was flying with a Mirage F.1CR in support of Italian Forces engaged with insurgents. Both crew ejected safely and were unhurt. The accident is presumed to be due to technical reasons but will be investigated.
Mirage F.1CR (643 '118-CE') from ER 02.033 at Mont-de-Marsan (BA 118) has just arrived at GERSA for storage, returning from strike/reconnaissance operations in Afghanistan it has 30 mission marks beside the cockpit. The Mirage F.1 is expected to remain in service with the AdA until 2014.
A Mirage F.1CR (662 '112-NF') in one of the climate controlled storage hangars on the Nivouville site. It has more recently arrived from Reims air base (BA 112) which was closed in September 2011. Due to its age and its tendency to leak the Mirage F.1 gives GERSA the most problems.
Outside the Battle Damage Repair unit (L'Equipe d'études techniques de réparation des dommages dus au combat - EETRDC 64.600), some of their aircraft including; Jaguar A, Mirage 2000C, Mirage F.1C and a wingless C-160 Transall. Formed in 1982 the EETRDC comes under the command of the CSFA at Bordeaux. Its mission is to find fast and simple methods for repairing aircraft damaged in combat and to offer training to other units on these techniques.

The Châteaudun airfield is situated on the outskirts of the town in the Eure-et-Loir department in central France, 71 miles (115 km) south of Paris. The air base was constructed for the AdA in 1934. Leading up to World War II it was used for the storage and supply of aircraft and also as a maintenance depot. In May 1940 during the Battle of France the Luftwaffe bombed the airfield. At that time 643 aircraft were stored at Châteaudun, with the German advance the airfield was abandoned.
For the next five years the Luftwaffe launched and supported raids from here over England, with Messerschmitt Bf 109, Junkers Ju 88, and Heinkel He 177 and from July 1944 with their new jet powered Messerschmitt Me 262, which flew interceptor missions against American heavy bomber attacks. The airfield was liberated by Allied ground forces during August 1944, a week later Northrop P-61 Black Widows arrived for air defence followed by Martin B-26 Marauders of the 387th Bombardment Group which were based from September to the end of October 1944. As the Allies advanced eastwards the airfield was used by Douglas C-47’s for transport duties until the end of the war, when it was returned to French control.
