Aircraft Engine Overhaul Shops - 300 times around the world: For the first time, the engine of a commercial aircraft travels about 12 million kilometers before it needs repair. With experience, expertise and precision, we ensure that it works reliably
There are more than 15,000 individual parts in a Rolls-Royce engine. We analyze, clean, repair or replace what is needed in a structured and strictly controlled process and get the engine running for the next years of reliable aircraft operation.
Aircraft Engine Overhaul Shops
The scope of our maintenance work always depends on the customer's order. After the first inspection of the engine, our production engineers turn it into a detailed work plan, keeping in mind the requirements of the law and production requirements.
Jet Engine Maintenance: This Is How We Do It
In a U-shaped clockwise flow, engine parts move from one station to another. The optimized arrangement of all operating areas, equipment and material stations ensures efficient material flow, maximum flexibility, short distances and maximum transparency.
At our workshop, repair and maintenance shop, each engine is carefully disassembled into individual parts. During the initial inspection, the engine is first checked for hidden damage
Next, all non-modular parts, e.g. pipe, removed The crane then lifts the engine into a vertical position This vertical approach, unique to the N3, allows for material-friendly isolation of the engine modules. The mechanics work particularly efficiently and ergonomically in all four engine versions with the help of an electrically operated lifting platform. The modules are further divided into individual parts or breakdown parts of their modules
The heart of the area is the cleaning facility, which has a total of 28 cleaning tanks for contamination, contamination, paint removal and rust removal. Each container holds approximately one and a half cubic meters and the diameter enables the machining of components up to 2 meters in diameter and weighing 500 kg.
Sustainair Sustainability Snapshots: Circular Maintenance
The entire cleaning area is closed Exhaust air is removed and prepared in the basement for re-use Process water is included in the cleaning line and is used several times in a multi-phase cycle The addition of several blowing machines and flexible manual workstations enables individual cleaning of almost all components.
After cleaning, our staff inspects the engine parts for possible damage Non-destructive testing methods (NDT) are used. These include fluorescent penetrant inspection (FPI), magnetic particle inspection (MPI) and X-ray imaging.
For particularly complex engine components, such as blades or welds, other destructive testing methods have been developed: FPI, MPI and X-ray analysis based on user experience and a trained eye, turbulent flow and ultrasonic testing give a more accurate measurement result. .
Here, all engine parts and components are compared to the permitted limits and evaluated for reusability and/or rebuildability. Based on the detected damage, our staff selects the necessary repair process, taking into account technical and financial aspects.
The Difference Between Line, Base And Component Maintenance
In research reports, they document all garment patterns with the highest accuracy. If the part is intact, it is directed to the "Reservation" field. If repair is needed, the relevant part is sent to the N3 internal repair shop or sent for external processing and repair. We keep spare parts in our warehouse until proper disposal
In addition to servicing all engine components, N3 also repairs the quality of new parts We also offer reliable personal repairs to international customers
After the inspection, it is decided whether to replace, repair, or fix a part. Our repair planners create a comprehensive workflow for each order that complies with legal requirements and manufacturing requirements. We guarantee our customers fast and reliable performance
Our state-of-the-art equipment enables complex repairs, maintenance work and modification work perfectly. You can find more detailed information about all repair procedures here
A Brief History Of The Pt6a Engine
All parts - damaged, new and repaired - are assembled separately for engine assembly The mechanic assembles the modules, grinds and balances them and after internal inspection sends them to the engine assembly.
Grinding the rotor tips with a high-speed grinder optimizes the clearance between the rotor and the stator (housing). As a result, the efficiency of the engine improves and its kerosene consumption decreases
Even small imbalances can cause strong vibrations in the system at certain frequencies, N3 also works to balance fast rotating engine turbines and compressors. This extends their service life and ultimately improves the safety of the motors
The final assembly of the engine is also done with vertical suspension. This requires a lot of discipline, because even the slightest damage makes an expensive engine part unusable. This is why here at N3 we operate according to the most modern quality assurance processes: every process and every assembled part is checked and recorded in the assembly documents. Continuous monitoring measurements and the simultaneous execution of additional visual tests according to the principle of dual control increase safety.
Continental & Lycoming Engine Overhaul
After the installation of the entire engine, authorized personnel inspect all performed maintenance steps and compare them with the customer's specifications, work plans and manufacturer's requirements.
In a test cell with a cross-section of 14 x 14 meters, we check the performance of each engine regardless of the depth of the machine in N3.
The test is carried out in different stages according to the strict safety regulations given by the manufacturer Rolls-Royce: it must accurately demonstrate that the engine has the required mechanical operation and specified performance.
According to the latest acoustics study, the test cell was equipped with sound insulation with several damping systems.

If the engine has passed the test drive, a final comparison between the engine and Rolls-Royce's specified specifications is made before delivery and returned to the customer.
