42 43 u-47 CAUSE CEECRIPTION AND CCRRECTIVE ACTIONS 27 l i i o l l The DG 1C trip was due to high crankcase pressure. An investigation revealed that the l3 ;il l number 1 and 11 cylinder liners were scored. The scoring of the liners caused localized ;

ii,,l l heating and exhaust leakage into the oil sump. This, in turn, caused the high crankcase ;_

li63l l pressure. Following the completion of repairs and successful testing, DG IC was returned y

,,,4 l l to service at 1603 on 10/02/81.
