Chapter 4.4 - Application of the engine group concept

Chapter 4.4.4

Chapter 4.4.4 reads as follows:

The application for the engine group concept, if requested by the engine manufacturer or another party, shall be considered for certification approval by the Administration. If the engine owner, with or without technical support from the engine manufacture, decides to perform modifications on a number of similar engines in the owner's fleet, the owner may apply for an engine group certification. The engine's group may include a test engine on the test bench. Typical applications are similar modifications of similar engines in service or similar engines in similar operational conditions.

Interpretation:

For application of this section it should be interpreted that the applicant for the engine certification takes on the responsibilities of the "engine manufacturer" as elsewhere given within the NO_x Technical Code.
