Narrative:
Supplemental information from acn 96046: the preflight was completed with all engine cowlings appearing closed and locked. However, a crack was noticed in the #4 engine tail cone. At that point maintenance began repairs to the #4 tail cone. I periodically checked the progress of the repair and at no time did I notice the cowling on the #4 engine opened. Supplemental information from acn 96112: later we discovered that the cowl had become dislodged at ewr airport on takeoff. At ewr maintenance crews were replacing a patch on engine #4 exhaust cone. It was the first cold day of the season. It was rainy accompanied with a 14-15 KT wind at the time the repair was in progress.
