Aircraft Piston Engines and their Accessories are Our Core Business
Our objective is to consistently provide a high quality overhaul and repair service for Lycoming and Teledyne Continental Aircraft engines.
We build engines that will last.
We provide comprehensive warranty coverage for the work that we perform.
An outline of our engine overhaul processes is provided below:
Engine is photographed on arrival to provide a record of the general condition, the orientation of fittings, position of hoses, the engine accessories supplied with the engine etc.The details of all engine accessories such as, magnetos, carburetor, fuel injector, alternator, starter motor, turbocharger are all recorded for future reference.
The engine log book is reviewed to verify the engine history and identify any other issues with the engine that may require attention.
Engine Stripped and Cleaned
Our engineers perform an initial visual inspection of all parts as they are being removed to identify any abnormal wear or other issues that may affect the operation of the engine.Mandatory parts and other un-repairable items that are to be replaced are separated and held.All parts are then thoroughly cleaned and readied for detailed inspection.
All the major steel parts are inspected for cracks and defects using the Magnetic Particle Technique.
The major alloy components are inspected for cracks and defects using the fluorescent dye penetrant technique.
Detailed dimension inspections are performed on all engine parts to check that they meet specifications.
Items such as connecting rods, counterweights, rocker arms are re-bushed.
Pistons, piston pins, and connecting rods are balanced. The new bearing shells are fitted the crankcase and connecting rods to ensure the correct fit and clearance when the engine is finally assembled.
Cylinders are overhauled or replaced with new assemblies in accordance with the customers instructions.
All parts are individually primed and painted prior to final assembly.
Engine hardware items such as nut, bolts and brackets are re-cad plated and stress relieved.
Engine component such as magnetos, fuel injection system, starters and alternators are overhauled and repaired as required.
During the overhaul and repair the components are bench tested and set to the initial calibration figures.
Each engine is assembled and built by a highly experienced and specialized engine builder.
At each stage during the final assembly of the engine, dual inspections are performed to verify the correct assembly of the engine.
Detailed records are kept of all the work done, and all the parts fitted to the engine for future reference.
After assembly each engine is thoroughly tested on either our dynamometer test cell, or conventional test truck to verify the correct operation of the engine.All engine operating parameters such as engine speed and manifold pressure, engine power, oil temperature and pressure, cylinder head temperatures, fuel flows and pressures, are all monitored and recorded.
Each engine is run for approximately 2 hours to achieve the initial break-in of the piston rings and to verify that the engine is operating correctly.
The oil filters used during the test run are opened and inspected. Oil suction screens are checked. Cylinder leakage rates are checked.
After removal from the test facility the engine is inhibited to stop corrosion.
A final inspection of the engine is conducted and the engine is prepared for shipping.
