Narrative:

Aborted takeoff twice when electronic engine control failed only after condition levers maximum and power being applied commencing takeoff roll. First abort routine with normal electronic engine control reset and taxi back. Second abort abnormal with #1 engine/propeller not properly responding to power reduction and reverse/beta position, with engine continuing to produce excess thrust, such that feathering #1 propeller best facilitated expediting clear of runway for landing traffic. After clearing runway and selecting electronic engine control manual, abnormal high ground idle power condition ceased. Electronic engine control 'south were deferred per company maintenance control and flight resumed late but routine with electronic engine control selected manual.

Title: AN EMB120 ABORTED TKOF TWICE DUE TO #1 ENG ELECTRONIC ENG CTL FAILURE.

Narrative: ABORTED TKOF TWICE WHEN ELECTRONIC ENG CTL FAILED ONLY AFTER CONDITION LEVERS MAX AND PWR BEING APPLIED COMMENCING TKOF ROLL. FIRST ABORT ROUTINE WITH NORMAL ELECTRONIC ENG CTL RESET AND TAXI BACK. SECOND ABORT ABNORMAL WITH #1 ENG/PROP NOT PROPERLY RESPONDING TO PWR REDUCTION AND REVERSE/BETA POS, WITH ENG CONTINUING TO PRODUCE EXCESS THRUST, SUCH THAT FEATHERING #1 PROP BEST FACILITATED EXPEDITING CLR OF RWY FOR LNDG TFC. AFTER CLRING RWY AND SELECTING ELECTRONIC ENG CTL MANUAL, ABNORMAL HIGH GND IDLE PWR CONDITION CEASED. ELECTRONIC ENG CTL 'S WERE DEFERRED PER COMPANY MAINT CTL AND FLT RESUMED LATE BUT ROUTINE WITH ELECTRONIC ENG CTL SELECTED MANUAL.
