Narrative:

As power was added for takeoff and takeoff roll began, right propeller was slow to accelerate. At approximately 10 KTS ground speed, and with left propeller indicating 98 percent, right propeller was indicating 78 percent, ccas engine and electric warnings were activated with low pitch and acw caution lights. Torque on right engine indicating 17.1 percent with power lever beyond 60 percent. Takeoff aborted. After clearing runway, acw generator reset per aom. Static runup normal. CTAF notified of acw generator trip. Coordinated with iah maintenance center who concurred that we could continue. Subsequent takeoff normal.

Title: COMMUTER MDT HAD TO ABORT A TKOF FROM DEN BECAUSE OF SLOW PWR ACCELERATION ON 1 ENG.

Narrative: AS PWR WAS ADDED FOR TKOF AND TKOF ROLL BEGAN, R PROP WAS SLOW TO ACCELERATE. AT APPROX 10 KTS GND SPD, AND WITH L PROP INDICATING 98 PERCENT, R PROP WAS INDICATING 78 PERCENT, CCAS ENG AND ELECTRIC WARNINGS WERE ACTIVATED WITH LOW PITCH AND ACW CAUTION LIGHTS. TORQUE ON R ENG INDICATING 17.1 PERCENT WITH PWR LEVER BEYOND 60 PERCENT. TKOF ABORTED. AFTER CLRING RWY, ACW GENERATOR RESET PER AOM. STATIC RUNUP NORMAL. CTAF NOTIFIED OF ACW GENERATOR TRIP. COORDINATED WITH IAH MAINT CENTER WHO CONCURRED THAT WE COULD CONTINUE. SUBSEQUENT TKOF NORMAL.
