Excellent Jet Service "EJS" - The Citation Specialists

Excellent Jet Service EJS was founded in 2018 to provide excellent Maintenance/Repair/Overhaul (MRO) for Textron Citation business jets – exactly as the chosen name suggests. The certified range of aircraft that can be supportd start with the smaller Citation Mustang (C510), the popular Citation Jets 1, 2 and 3 (C525/A/B) up to and including the versatile Citation XLS (C560XL). The very well-appointed hangar at Memmingen Airport allows all line and base maintenance events to be carried out diligently. In cases of a technical emergency, the mechanics and technicians of EJS can assist operators further afield, e.g. at Munich Airport or at Oberpfaffenhofen Airport.

EJS is certified for all permissable maintenance events and also has a separate certification for wheels and tyres. Even a heavy job such as a complete dismantling and deep inspection at hidden areas is possible, as well as all modofications, STC works and more. AOGs are the icing on every weeks’ work.

General Overhaul of an XLS – Part 1 Recently, EJS completed a major overhaul on a Citation XLS, which received a complete make-over inside and out. For this, the old and worn interior (cabin & cockpit) was removed, tagged and packed to be sent to a specialist interior company to be redone

to the customers’ choosing. The aircraft itself was inspected inside and out and all control surfaces removed – ailerons, elevators and the rudder, as well as flaps, engine covers and a few more covers and panels. All these are to painted separately. Before the paint hangar can be entered, a complete defueling will also take place under supervision of EJS and the airport fire guys.

The naked aircraft will then be towed to the paint hangar – often referred to as the paint shop and will be stripped of it sold paint. In Europe, this will be done solely using environmentally friendly and rather soft stripping chemicals. Often there are several layers of old paint that need to be removed which means this soft stripping needs to be repeated once or twice. Plastic parts (FRPs) will be sanded down.

After this process, EJS’ specialists will perform a thorough corrosion inspection and rectification as required. Sometimes, corroded spots are mere millimetres in size, but they must be removed to avoid growing bigger underneath the new layers of paint. Upon completion of this task by EJS will the paint shop continue with priming and painting of the aircraft. Beforehand, the paint scheme, colours and any additional works have been discussed with the customer by EJS and the paint shop.

The Re-assembly – the process of putting it all back together, follows then. Usually, this task takes twice as much time as the removals.

EJS takes care the entire process and and organisation of uch a project – not just in accordance with EASA Part-145, but also all other issues such as transports, materials, permits etc. This preliminary planning often takes manany months ahead oft he start date and is a logistic masterpiece, where all pieces have to fall precisely into place. This avoids excessive costs, delays and other issues.

Part 2 – new paint, new cabin and completion will follow in the next issue.
