Analysis
As coplt accelerated acft through 128 KTS for takeoff, electrical malfunction occurred resulting in unreliable instrument indications. Capt rejected takeoff. Acft went off end of 12000-FT rwy. Post-incident examination disclosed no. 1 constant speed drive (csd) output slowed due to oil leakage. Generator control unit tripped and opened line contactor. With removal of electrical load, csd output speed increased & electrical load reapplied. Cycle repeated itself every 0.84 seconds. Csd had never been overhauled in 10 yrs of service. Cvr/dfdr revealed electrical malfunction occurred at 1240:12 & abort command given at 1240:29. At 1240:26, when pwr was restored to dfdr, acft was decelerating thru 171.08 KIAS. V1,vr, & V2 computed to be 161, 161, and 165 KTS & accelerate-stop distance about 11,500 ft. investigation further revealed acft green brake system inop & yellow system used. Additionally, no. 7 brake antiskid inop. Both are allowable deferred maintenance items.
