This information shall be obtained by the engine manufacturer by use of prior endurance testing, based on normal operating cycles, and by calculation of component fatigue so that the necessary maintenance instructions may be prepared by the manufacturer and issued with all new engines when first placed on the market.
Proizvajalec motorja pridobi te informacije z izvedbo predhodnega preskusa vzdržljivosti, ki temelji na normalnih obratovalnih ciklih, in izračunom obrabe sestavnih delov, tako da lahko pripravi in izda potrebna navodila za vzdrževanje za vse nove motorje, ko so prvič dani v promet.
