6.2.3 Procedures for an engine parameter check method

  6.2.3.1 An engine parameter check method shall be carried out using the two procedures as follows:

  • .1 a documentation inspection of engine parameter(s) shall be carried out in addition to other inspections and include inspection of the record book of engine parameters and verification that engine parameters are within the allowable range specified in the engine’s technical file; and

  • .2 an actual inspection of engine components and adjustable features shall be carried out as necessary. It shall then be verified, also referring to the results of the documentation inspection, that the engine’s adjustable features are within the allowable range specified in the engine’s technical file.

  6.2.3.2 The surveyor shall have the option of checking one or all of the identified components, settings or operating values to ensure that the engine with no, or minor, adjustments or modifications complies with the applicable NOx emission limit and that only components of the approved specification, as given by 2.4.1.7, are being used. Where adjustments and/or modifications in a specification are referenced in the technical file, they must fall within the range recommended by the applicant for engine certification and approved by the Administration.
