Lycoming Engine Overhaul, Repair & Inspection in Europe

Specialist Lycoming Engine Services from Poland

Helimot specialises in the overhaul, repair, inspection, maintenance and testing of Lycoming piston aircraft
engines.

Based in Poland, we provide professional Lycoming engine services to aircraft owners, operators, maintenance
organisations and aviation companies from Poland and across Europe.

Our capabilities cover the complete engine maintenance process — from initial inspection and fault diagnosis, through
detailed dimensional inspection, component repair and engine overhaul, to final assembly and engine test-cell
testing.

We also specialise in Lycoming engine inspections following propeller strikes, sudden stoppage events and
engine overspeed conditions.

Lycoming Engine Overhaul

We perform complete Lycoming engine overhauls and major repairs, with every engine individually inspected
and evaluated before assembly.

A Lycoming engine overhaul is a complex process that requires detailed inspection, accurate dimensional measurements
and careful evaluation of the condition of each critical component.

Our overhaul process may include:

• complete engine disassembly and inspection,
• cleaning and detailed visual inspection,
• dimensional inspection of engine components,
• crankshaft inspection and measurement,
• connecting rod inspection,
• camshaft and cam lobe inspection,
• cylinder and piston inspection,
• bearing inspection,
• gear and accessory drive inspection,
• NDT examinations where required,
• replacement or repair of unserviceable components,
• engine assembly,
• final inspection,
• engine run and performance verification in our test cell.

We use the applicable Lycoming technical data and maintenance requirements for the engine being serviced.
Lycoming's current technical documentation includes engine-specific maintenance and overhaul information, while
mandatory requirements can also be issued through Service Bulletins, Service Instructions and other service
publications.

Our objective is not simply to replace parts. We focus on identifying the actual cause of an engine problem,
determining the condition of the complete engine and returning the unit to service in accordance with applicable
requirements.

Lycoming Engine Repair

Not every Lycoming engine requires a complete overhaul.

We provide Lycoming engine repair and troubleshooting services for engines with specific defects, abnormal
operating parameters or damaged components.

Depending on the findings, we can inspect and repair individual components or carry out a more comprehensive engine
inspection when required.

Our experience covers issues involving:

• crankshafts,
• camshafts,
• cylinders,
• pistons and piston rings,
• connecting rods,
• bearings,
• gears,
• oil systems,
• fuel systems,
• ignition systems,
• abnormal oil consumption,
• low or unstable oil pressure,
• metal contamination,
• unusual engine noises,
• vibration and performance problems.

Where appropriate, we carry out additional measurements and NDT inspections to establish the serviceability of the
affected components.

Lycoming Propeller Strike Inspection

Propeller Strike, Sudden Stoppage & Shock Load Inspection

We provide specialised Lycoming propeller strike inspections following propeller strikes, sudden engine stoppage
and other events that may have subjected the engine to abnormal loads.

A propeller strike can transmit significant loads through the propeller, crankshaft and engine drive system. Damage may
not always be visible externally, which is why a detailed internal inspection is essential.

Depending on the event and engine model, the inspection may include:

• crankshaft inspection,
• crankshaft dimensional measurements,
• connecting rod inspection,
• bearing inspection,
• gear train inspection,
• camshaft inspection,
• accessory drive inspection,
• engine case inspection,
• NDT examinations,
• inspection of other components potentially affected by the event.

Our goal is to establish the actual condition of the engine and determine which components remain serviceable and
which require repair or replacement.

Lycoming Overspeed Inspection

We also perform Lycoming engine overspeed inspections following operation above the approved engine RPM
limits.

An overspeed event can place additional loads on rotating components and the valve train. The extent of the required
inspection depends on the engine model, severity and duration of the overspeed event and the applicable maintenance
requirements.

We assess the engine and its components to determine whether further inspection, dimensional checks, NDT or
component replacement is required.

Lycoming Engine Test Cell

Engine Testing After Overhaul & Repair

One of Helimot's key capabilities is our dedicated Lycoming engine test cell.

Following an overhaul or major repair, we can run the engine under controlled conditions and monitor its operating
parameters.

Test-cell testing allows us to verify engine operation and identify potential issues before the engine is installed in the
aircraft.

Depending on the engine and test requirements, we can monitor parameters such as:

• engine RPM,
• oil pressure,
• oil temperature,
• cylinder head temperature,
• exhaust gas temperature,
• fuel pressure,
• manifold pressure,
• engine performance and stability.

The test cell forms an important part of our quality-control process and provides an additional level of confidence
following a major engine overhaul or repair.

Lycoming Engines We Service

Our experience covers a wide range of Lycoming piston aircraft engines, including:

4-Cylinder Lycoming Engines

• O-235
• O-290
• O-320
• O-340
• O-360

6-Cylinder Lycoming Engines

• O-435
• O-480
• O-540
• O-580

8-Cylinder Lycoming Engines

• O-720

We also work with different Lycoming engine configurations and variants, including:

• O – carbureted engines
• IO – fuel-injected engines
• AEIO – aerobatic engines
• TIO – turbocharged, fuel-injected engines
• HIO – helicopter applications
• other Lycoming piston engine variants, depending on the specific model and applicable maintenance requirements.

Lycoming's product range contains a large number of engine variations, and the exact overhaul and inspection
requirements depend on the complete engine model and configuration.

Complete Lycoming Engine Support

Whether your engine requires a complete overhaul, major repair, troubleshooting, propeller strike inspection, overspeed inspection or post-maintenance testing, Helimot can provide a comprehensive solution.

Our facility allows us to manage the major stages of the process in one location:

Inspection → Measurement → Assessment → Repair / Overhaul → Assembly → Test Cell → Final Inspection

This integrated approach gives us greater control over the quality of the work and allows us to identify potential
problems before the engine returns to aircraft operation.
