DURING A PREFLT, JUST PRIOR TO TAKEOFF, THE PLT CHECKED THE FLT CONTROLS & FULL TRAVEL OF THE CONTROLS WAS ACHIEVED. HE INITIATED THE TAKEOFF, BUT WHEN HE APPLIED BACK PRESSURE ON THE ELEVATOR CONTROL, IT WOULD ONLY MOVE ABOUT 1 INCH. HE ABORTED THE TAKEOFF WITHOUT FURTHER INCIDENT. AN EXAM OF THE ACFT REVEALED THE RIBBON WIRE, PN 1570308-1, FOR THE CONTROL YOKE ELECTRICAL SWITCHES BECAME JAMMED UNDER THE CONTROL COLUMN BEARINGS & RESTRICTED THE YOKE MOVEMENT. AN EXCESSIVE AMOUNT OF SLACK IN THE WIRE WAS NOTED. A CESSNA SERVICE LETTER, SE79-26, REGARDING 1978 & 1979 CESSNA 210 & P210 MODELS ADDRESSED THIS PROBLEM, BUT WAS NOT APPLICABLE TO PREVIOUS MODELS. N21YF WAS A 1974 CESSNA T2101. STARTING IN 1980, GUIDES WERE INSTALLED AT THE FACTORY. WHEN REMOVED, THE RIBBON WIRE WAS 33' LONG & WAS SPLIT FOR USE IN THE 1974 ACFT. THE REPLACEMENT RIBBON WIRE WAS 45' LONG, WAS NOT SPLIT & WAS MADE FOR USE IN SEVERAL MODELS OF CESSNA ACFT. THE SERVICE MANUAL HAD NO INSTRUCTIONS FOR INSTALLATION EXCEPT FOR A DIAGRAM.
