INAPPROPRIATE ABORT.

Narrative

CREW CONSISTED OF A NEW UPGRADE CAPT -- COMPANY DEFINED AS 'INEXPERIENCED' (LESS THAN 100 HRS IN TYPE) AND A NEW FO. COMPANY PROC CALLS FOR ACFT CTL TRANSFER TO PF AT 70 KTS; THEN PNF MAKES SPD CALLS (THIS CASE; THE CAPT). CAPT TRANSFERRED CTL OF ACFT TO THE FO THEN CALLED V1; ROTATE; AT WHICH TIME ACFT PITCH WAS INCREASED. SIMULTANEOUSLY WITH THIS EVENT (JUST AFTER V1 CALL) CAPT CALLED AND INITIATED ABORT BY REDUCING PWR COMPLETELY. ACFT WAS MOMENTARILY AIRBORNE AND FO LANDED; CAPT APPLIED REVERSE AND BRAKES. ACFT STOPPED ON RWY WITHOUT INCIDENT AND RETURNED TO GATE. THE CAPT SAID REASON FOR ABORT WAS A 'DRAG OR YAW TO THE L' THAT HE INTERPRETED AS AN IMPENDING PWR-PLANT FAILURE. ALL PWR GAUGES AND CAPTION PANEL WAS NORMAL. FO DIDN'T NOTICE ANYTHING THAT WARRANTED AN ABORT; HOWEVER; UPON ROTATION AND MAINTAINING DIRECTIONAL CTL RUDDER HANDLING OR INADVERTENT TOUCHING OF BRAKES COULD HAVE PRODUCED SLIGHT YAW. THE PROB LIES IN THE FACT THAT THE ABORT WAS MADE AFTER V1 CALL AND ACFT WAS TRANSITIONING TO FLT. A DECISION TO CONTINUE TKOF AFTER V1 SHOULD NOT HAVE TO BE CONSIDERED (EVEN IF THE PERCEPTION IS ADEQUATE RWY REMAINS). HOWEVER; IN THOSE PRECIOUS MOMENTS IT APPEARED INSTINCT OVERRULED TRAINING.
