## Discrepancy

THE PITCH SERVO OVERHEATED CAUSING SMOKE IN THE COCKPIT.  THE CURRENT LIMITING RESISTOR HAD MELTED.  THE PILOT REPORTED THAT THE AIRCRAFT HAD EXPERIENCED SOME MINOR PORPOISING PRIOR TO THE SMOKE.  THIS IS THE THIRD TIME THIS ACFT HAS EXPERIENCED THIS PROBLEM AND THE 3RD S/N WITH THE SAME PROBLEM.
