Narrative:

During takeoff roll at ord, a momentary indication of autofeather was noted. We immediately aborted all indications returned to normal. Upon clearing the active runway, the captain contacted maintenance control. Although I did not hear the conversation, the captain conveyed to me that since all indications were now normal another takeoff attempt was at our discretion. We then did a static runup and all indications remained normal the captain then decided to try another takeoff. Although I was hesitant about the safety and legality of another takeoff, I did not press the issue very hard. Against my better judgement another takeoff was attempted. Immediately upon bringing the power up on the second takeoff, another temporary autofeather indication was noted. We aborted and returned to the gate. This second abort could have been avoided had I been more forceful about my reservations. Crew concept and mutual decision making should have been more a part of this incident. Also, maintenance control should have had us return to the gate immediately. This would have left no question to us (the crew) whether or not another takeoff should be attempted.

Title: TKOF ABORTED WHEN SERIOUS ACFT EQUIP PROBLEM SURFACES ON TKOF ROLL. FO RPTR QUESTIONS SECOND TKOF ATTEMPT AFTER THE FACT.

Narrative: DURING TKOF ROLL AT ORD, A MOMENTARY INDICATION OF AUTOFEATHER WAS NOTED. WE IMMEDIATELY ABORTED ALL INDICATIONS RETURNED TO NORMAL. UPON CLRING THE ACTIVE RWY, THE CAPT CONTACTED MAINT CTL. ALTHOUGH I DID NOT HEAR THE CONVERSATION, THE CAPT CONVEYED TO ME THAT SINCE ALL INDICATIONS WERE NOW NORMAL ANOTHER TKOF ATTEMPT WAS AT OUR DISCRETION. WE THEN DID A STATIC RUNUP AND ALL INDICATIONS REMAINED NORMAL THE CAPT THEN DECIDED TO TRY ANOTHER TKOF. ALTHOUGH I WAS HESITANT ABOUT THE SAFETY AND LEGALITY OF ANOTHER TKOF, I DID NOT PRESS THE ISSUE VERY HARD. AGAINST MY BETTER JUDGEMENT ANOTHER TKOF WAS ATTEMPTED. IMMEDIATELY UPON BRINGING THE PWR UP ON THE SECOND TKOF, ANOTHER TEMPORARY AUTOFEATHER INDICATION WAS NOTED. WE ABORTED AND RETURNED TO THE GATE. THIS SECOND ABORT COULD HAVE BEEN AVOIDED HAD I BEEN MORE FORCEFUL ABOUT MY RESERVATIONS. CREW CONCEPT AND MUTUAL DECISION MAKING SHOULD HAVE BEEN MORE A PART OF THIS INCIDENT. ALSO, MAINT CTL SHOULD HAVE HAD US RETURN TO THE GATE IMMEDIATELY. THIS WOULD HAVE LEFT NO QUESTION TO US (THE CREW) WHETHER OR NOT ANOTHER TKOF SHOULD BE ATTEMPTED.
