What was found
ON TAKEOFF ROLL, THE RT ENGINE QUIT. AFTER TROUBLESHOOTING, AND CHANGING MAGS, THE ENGINE STILL ONLY RAN ROUGH, AT BEST. THE ENGINE WAS REPLACED AND SENT BACK TO OVERHAUL FACILITY. AT TEAR DOWN IT WAS FOUND THAT THE DOWEL THAT ALIGNS THE CRANKSHAFT GEAR TO THE SHAFT HAD SHEARED, ALLOWING THE GEAR TO SLIP. (K)
