CS-E 370 Starting Tests

(a)At least 100 successful Engine starts must be made, either during or at the end of the endurance test of CS-E 440, using the normal means of starting and the technique recommended by the Engine constructor. Half the starts must be made with the Engine cold and half with the Engine hot.

(b)Time to start, number of attempts, ambient air temperature, and (in the case of electric starters) current consumption, must be recorded at the beginning of each 10-hour period. In addition, a record must be made of the means and amount of priming, if employed, and whether or not oil dilution is used.

(c)If alternative means of starting are provided for emergency or standby use, not less than 10 additional starts on each of the alternative means of starting provided must be made. These tests may be made either as part of the endurance test of CS-E 440 or separately in which case they must be followed by a suitable strip examination.
