general description of the origin and buildup of the engine, steps taken 
to ensure that it is representative of production engines, description 
of components specially built for the test engine, and the origin and 
description of all emission-related components;
    (ii) A description of the method used for service accumulation, 
including date(s) and the number of hours accumulated;
    (iii) A description of all maintenance, including modifications, 
parts changes, and other servicing performed, and the date(s) and
