Piracy has nothing to do with alternative supplies....

Definition by wikipedia
Piracy is a war-like act committed by private parties (not affiliated with any government) that engage in acts of robbery and/or criminal violence at sea. The term can include acts committed in other major bodies of water or on a shore. It does not normally include crimes committed against persons travelling on the same vessel as the perpetrator (e.g. one passenger stealing from others on the same vessel). The term has been used to refer to raids across land borders by non-state agents. Piracy should be distinguished from privateering, which was a legitimate form of war-like activity by non-state actors, authorized by their national authorities, until this form of commerce raiding was outlawed in the 19th century.

The word pirate parts does not exist – The correct word would be alternative supply. Example a fuel nozzle from produced by L’orange purchased at engine builder would be original, however is the same nozzle purchased L’orange or other source (Still same nozzle) this would be considered an alternative supply. There is many suppliers, some better than others – agreed, but is is to easy to generalize. Warranty is a definitely
and issue and lifetime as well, but given the case with the nozzle, there are many identical cases with other components. In most cases problems with specific components tend to take time for replacing from an engine manufacture point of view as there is a lot of things to be taken in consideration, however this does not serve the clients immediate need, therefore alternative solutions are needed. I fully agree that the engine builders can support 92 % of the requirements, but some times it is the last 8 % that keep the vessels in operation. And the engine builder can not reschedule and re-arrange production due to one clients requirement. Further to that most of the alternative suppliers have general conditions and insurance beyond normal, and better than some builders. We need to be critical, but not blind or deaf. Alternatively we would end up in monopolized marked, and the question then remain… Would we have a better situation than today…
