Narrative:
A Lockheed L-1329 JetStar four engine corporate jet was damaged beyond repair in a runway excursion accident at Miami International Airport, FL (MIA).
The flight was a 3-engine ferry flight to Dallas-Love Field, TX (DAL) with the no. 4 engine shut down. During takeoff roll at V1 the no. 2 engine overheat light came on. According to the copilot the pilot reduced throttle slightly and continued the takeoff. After lift-off the pilot aborted the takeoff. The airplane could not be stopped on the remaining runway and collided with antennas, approach lights and a construction site 1,180 ft from the departure end of runway 09L. Post-crash examination of the 3 operating engines did not reveal any evidence of mechanical failure or malfunction. A failed resistor was found in the no. 2 engine electronic engine control (EEC). This would cause the unit to over-schedule fuel to the engine resulting in hotter engine operating temperatures. Retarding the throttle would reduce fuel flow to within normal ranges for engine operation. Under conditions that existed at the time of the accident, the airplane would have a 3-engine rate-of-climb of 1,398 fpm, and a 2-engine rate-of-climb of 350 fpm.

Probable Cause:

PROBABLE CAUSE: "The pilot's improper decision to reject the takeoff after the airplane had passed V1 speed and lifted off the runway. A factor was a malfunctioning #2 engine electronic engine control which caused the unit to over-schedule fuel to the engine resulting in hotter operating temperatures."
