This warranty shall not apply to Equipment or Parts that have been subject to misuse, neglect, deterioration, foreign object damage, tampering, improper storage, fuel contamination, detonation, pre-ignition, accident or operated beyond manufacturer’s limits such as, but not limited to, speed, temperature or manifold pressure.

To assist you in understanding your obligations with regard to the operation of your engine or component, and to ensure you do not inadvertently compromise any warranty coverage that you are entitled to, below is a discussion about some aspects of the operation of your engine and warranty provisions for your consideration.


It is a condition of your warranty that your engine is maintained in an airworthy, mechanically sound condition and serviced regularly in accordance with the engine manufacturer’s recommendations and standard practices.

In particular we would like to emphasis that while your engine or components may have been operated, or bench tested prior to delivery, further adjustment may be required when the engine or component is installed.

Fuel system adjustments are particularly important. Please ensure the idle speed and mixture is correctly set, and that full power fuel flow is correctly adjusted and set as specified by the engine / aircraft manufacturer. For some engines this may require flying the aircraft, observing the fuel flows, making adjustments, and then re-checking the fuel flows.

Any defect or fault or any parts identified as needing repair or replacement or which are identified as a potential problem must be rectified as soon as physically possible.

Upon becoming aware of the development of any problem, you, or any other person operating the engine must take all necessary steps to minimise any damage that might arise.

Generally Warranty does not cover:

  • any service or maintenance items, adjustments or any expendable items as specified under the heading Maintenance items.

  • any problem caused by the use of incorrect types & grades of fuel, oil or lubricants.

  • any problem caused by the failure to maintain proper levels of fluids, lubricants, fuels, or contamination of fluids.

  • any problem caused by detonation or pre-ignition caused by operator mishandling.

  • failure arising from normal wear and tear and the gradual reduction of in operating performance of the engine or component.

  • diagnostic costs unless accepted as part of an authorised claim.

  • components which have not failed and which are replaced during routine servicing or maintenance.

  • engines that have not been maintained in accordance with the service requirements.

  • any repairs required as a result of continued operation of the engine once a defect or fault has been identified.

  • the costs incurred in improving or reconditioning the engine or components to a condition superior to that at time of defect or fault occurring.

  • any problems caused by misuse, neglect, abuse or improper servicing, dust, chemicals, fire, illegal use, malicious damage, impact, accident or corrosion.

  • any subsistence charges such as accommodation, and food.

  • any cost associated with travelling expenses for either you, or for maintenance personnel.

  • any consequential loss or damage of any kind.

Maintenance Items

The service, maintenance & expendable items that are not covered by Warranty include:

  • All Routine engine maintenance and adjustments.

  • All air filters, oil filters, spark plugs, and similar consumable items.

  • The cleaning of fuel nozzles and flushing of fuel lines.

  • Consumables such as oils and lubricants unless required as a direct result of the failure of covered component.

  • Stripped threads and fastening devices.

If you are unfortunate and need to make a warranty claim, please contact us before you commence or authorise any repairs.

As I hope you understand, if we a making a warranty claim on your behalf to a manufacturer, we have procedures that we are required to follow, and approvals to obtain before any repairs can the authorised.

If you proceed with any repairs before the manufacturer has authorised any repairs to be performed, you may have to pay the costs of the repairs that you authorised.

One area that can be contentious, is who pays the costs, for additional work that maybe required, that is not the direct warranty repair required.

For example, the time required to remove and refit engine cowls may take a few minutes on one aircraft, and a few hours on another aircraft. Similarly with some aircraft, cylinders and engine accessories are readily accessible, while in other aircraft, it may be necessary to remove the entire engine to gain access to the required part of the engine or engine accessory. Some aircraft are relatively well designed from the perspective of performing maintenance, while others, are very difficult and time consuming.

Due to the wide range of circumstances and possible scenarios, it is not possible to provide a universal answer to this question of who pays for any additional costs that may not be covered by the manufacturer’s warranty.

In the event of a warranty claim, this is generally an issue that has to be addressed on a case by case basis.
